    Atmospheric and astrophysical neutrinos above 1 TeV interacting in IceCube2015Inngår i: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 91, nr 2, s. 022001-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The IceCube Neutrino Observatory was designed primarily to search for high-energy (TeV-PeV) neutLrinos produced in distant astrophysical objects. A search for. greater than or similar to 100 TeV neutrinos interacting inside the instrumented volume has recently provided evidence for an isotropic flux of such neutrinos. At lower energies, IceCube collects large numbers of neutrinos from the weak decays of mesons in cosmic-ray air showers. Here we present the results of a search for neutrino interactions inside IceCube's instrumented volume between 1 TeV and 1 PeV in 641 days of data taken from 2010-2012, lowering the energy threshold for neutrinos from the southern sky below 10 TeV for the first time, far below the threshold of the previous high-energy analysis. Astrophysical neutrinos remain the dominant component in the southern sky down to a deposited energy of 10 TeV. From these data we derive new constraints on the diffuse astrophysical neutrino spectrum, Phi(v) = 2.06(-0.3)(+0.4) x 10(-18) (E-v = 10(5) GeV)-2.46 +/- 0.12GeV-1 cm(-2) sr(-1) s(-1) for 25 TeV < E-v < 1.4 PeV, as well as the strongest upper limit yet on the flux of neutrinos from charmed-meson decay in the atmosphere, 1.52 times the benchmark theoretical prediction used in previous IceCube results at 90% confidence.

    Multipole analysis of IceCube data to search for dark matter accumulated in the Galactic halo2015Inngår i: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 75, nr 1, artikkel-id 20Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Dark matter which is bound in the Galactic halo might self-annihilate and produce a flux of stable final state particles, e. g. high energy neutrinos. These neutrinos can be detected with IceCube, a cubic-kilometer sized Cherenkov detector. Given IceCube's large field of view, a characteristic anisotropy of the additional neutrino flux is expected. In this paper we describe a multipole method to search for such a large-scale anisotropy in IceCube data. This method uses the expansion coefficients of a multipole expansion of neutrino arrival directions and incorporates signal-specific weights for each expansion coefficient. We apply the technique to a high-purity muon neutrino sample from the Northern Hemisphere. The final result is compatible with the null-hypothesis. As no signal was observed, we present limits on the self-annihilation cross-section averaged over the relative velocity distribution <sigma(A)v > down to 1.9x10(-23) cm(3) s(-1) for a dark matter particle mass of 700-1,000 GeV and direct annihilation into nu(nu) over bar. The resulting exclusion limits come close to exclusion limits from gamma-ray experiments, that focus on the outer Galactic halo, for high dark matter masses of a few TeV and hard annihilation channels.

    Energy based methods applied in mechanics by using the extended Noether's formalism2023Inngår i: Zeitschrift für angewandte Mathematik und Mechanik, ISSN 0044-2267, E-ISSN 1521-4001, Vol. 103, nr 12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Physical systems are modeled by field equations; these are coupled, partial differential equations in space and time. Field equations are often given by balance equations and constitutive equations, where the former are axiomatically given and the latter are thermodynamically derived. This approach is useful in thermomechanics and electromagnetism, yet challenges arise once we apply it in damage mechanics for generalized continua. For deriving governing equations, an alternative method is based on a variational framework known as the extended Noether's formalism. Its formal introduction relies on mathematical concepts limiting its use in applied mechanics as a field theory. In this work, we demonstrate the power of extended Noether's formalism by using tensor algebra and usual continuum mechanics nomenclature. We demonstrate derivation of field equations in damage mechanics for generalized continua, specifically in the case of strain gradient elasticity.

    Measurement of the Forward-Backward Asymmetry in the Production lof B-+/- Mesons in p(p)over-bar Collisions at root s=1.96 TeV2015Inngår i: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 114, nr 5Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present a measurement of the forward-backward asymmetry in the production of B-+/- mesons, A(FB)(B-+/-) using B-+/- -> J/ Psi K-+/- decays in 10.4 fb(-1) of p (p) over bar collisions at root s = 1.96 TeV collected by the D0 experiment during Run II of the Tevatron collider. A nonzero asymmetry would indicate a preference for a particular flavor, i.e., b quark or (b) over bar antiquark, to be produced in the direction of the proton beam. We extract A(FB) (B-+/-) from a maximum likelihood fit to the difference between the numbers of forward-and backward-produced B-+/- mesons. We measure an asymmetry consistent with zero: A(FB) (B-+/-) = [-0.24 +/- 0.41 (stat) +/- 0.19 (syst)] %.

    Combining Maximum-Likelihood with Deep Learning for Event Reconstruction in IceCube2022Inngår i: 37th International Cosmic Ray Conference (ICRC 2021) / [ed] Alexander Kappes; Bianca Keilhauer, Sissa Medialab Srl , 2022, artikkel-id 1065Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The field of deep learning has become increasingly important for particle physics experiments, yielding a multitude of advances, predominantly in event classification and reconstruction tasks. Many of these applications have been adopted from other domains. However, data in the field of physics are unique in the context of machine learning, insofar as their generation process and the laws and symmetries they abide by are usually well understood. Most commonly used deep learning architectures fail at utilizing this available information. In contrast, more traditional likelihood-based methods are capable of exploiting domain knowledge, but they are often limited by computational complexity.

    In this contribution, a hybrid approach is presented that utilizes generative neural networks to approximate the likelihood, which may then be used in a traditional maximum-likelihood setting. Domain knowledge, such as invariances and detector characteristics, can easily be incorporated in this approach. The hybrid approach is illustrated by the example of event reconstruction in IceCube.

    Precision measurement of the D*(0) decay branching fractions2015Inngår i: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 91, nr 3, artikkel-id 031101Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Using 482 pb(-1) of data taken at root s = 4.009 GeV, we measure the branching fractions of the decays of D*(0) into D-0 pi(0) and D-0 gamma to be B(D*(0) -> D-0 pi(0)) = (65.5 +/- 0.8 +/- 0.5)% and B(D*(0) -> D0 gamma) = (34.5 +/- 0.8 +/- 0.5)%, respectively, by assuming that the D*(0) decays only into these two modes. The ratio of the two branching fractions is B(D*(0) -> D-0 pi(0))/B(D*(0) -> D-0 gamma) = 1.90 +/- 0.07 +/- 0.05, which is independent of the assumption made above. The first uncertainties are statistical and the second ones systematic. The precision is improved by a factor of 3 compared to the present world average values.

    Thermal oxidation of sputtered nickel nano-film as hole transport layer for high performance perovskite solar cells2019Inngår i: Journal of materials science. Materials in electronics, ISSN 0957-4522, E-ISSN 1573-482X, Vol. 30, nr 22, s. 19792-19803Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The effect of rapid oxidation temperature on the sputtered nickel (Ni) films to act as a hole transport layer (HTL) for perovskite solar cell (PSCs) was investigated. A nano-sputtered Ni film with a thickness about 100 nm was oxidized at a range of different oxidation temperatures between 350 and 650 °C to work as HTL in an inverted p–i–n configuration. DC Hall measurement in van der Pauw configuration and photoluminescence spectroscopy were used to measure the charge’s mobility and extraction of nickel oxide (NiO) films. The behaviour of the carrier concentration measurements of NiO layers at different oxidation temperatures showed that the Ni layer oxidized at 450 °C had the highest carrier concentration among the other samples. The performance measurements of the fabricated PSCs showed that the nickel oxide hole-transporting layer which has been oxidized at the optimum oxidation temperature of 450 °C has the highest power conversion efficiency (PCE) of 12.05%. Moreover, the characteristic parameters of the optimum cell such as the open-circuit voltage (VOC), short-circuit current density (JSC) and fill factor (FF) were 0.92 V, 19.80 mA/cm2 and 0.331, respectively.

    Correlative Experimental and Theoretical Investigation of the Angle-Resolved Composition Evolution of Thin Films Sputtered from a Compound Mo2BC Targe2019Inngår i: Coatings, ISSN 2079-6412, Vol. 9, nr 3, artikkel-id 206Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The angle-resolved composition evolution of Mo-B-C thin films deposited from a Mo2BC compound target was investigated experimentally and theoretically. Depositions were carried out by direct current magnetron sputtering (DCMS) in a pressure range from 0.09 to 0.98 Pa in Ar and Kr. The substrates were placed at specific angles α with respect to the target normal from 0 to ±67.5°. A model based on TRIDYN and SIMTRA was used to calculate the influence of the sputtering gas on the angular distribution function of the sputtered species at the target, their transport through the gas phase, and film composition. Experimental pressure- and sputtering gas-dependent thin film chemical composition data are in good agreement with simulated angle-resolved film composition data. In Ar, the pressure-induced film composition variations at a particular α are within the error of the EDX measurements. On the contrary, an order of magnitude increase in Kr pressure results in an increase of the Mo concentration measured at α = 0° from 36 at.% to 43 at.%. It is shown that the mass ratio between sputtering gas and sputtered species defines the scattering angle within the collision cascades in the target, as well as for the collisions in the gas phase, which in turn defines the angle- and pressure-dependent film compositions.

    Path Integrals in Quantum Mechanics and Low-Dimensional QFT2023Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. The path integral uses the principle of least action to sum over all such intermediate states to find the evolution of a quantum mechanical system. We compare the path integral approach to that of the Schrödinger equation and show that the two give an equivalent description of quantum mechanics.

    To demonstrate the usefulness of the path integral, we introduce low-dimensional quantum field theory (QFT). In particular, we discuss Feynman diagrams. The idea behind Feynman diagrams is to sum over all possible weak interactions between fields to evaluate the properties of a system through the path integral. We also carry out a computation of a low energy effective action in a 0-dimensional model. The result of the computation shows that there is free energy also in a vacuum. Finally, we briefly generalize some of the previous discussion to 1-dimensional QFT. To give an example of a practical application, we give a qualitative discussion of how the path integral can be applied to statistical mechanics to predict the behaviour of superfluids.

    Towards neutron scattering experiments with sub-millisecond time resolution2015Inngår i: Journal of applied crystallography, ISSN 0021-8898, E-ISSN 1600-5767, Vol. 48, s. 220-226Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Neutron scattering techniques offer several unique opportunities in materials research. However, most neutron scattering experiments suffer from the limited flux available at current facilities. This limitation becomes even more severe if time-resolved or kinetic experiments are performed. A new method has been developed which overcomes these limitations when a reversible process is studied, without any compromise on resolution or beam intensity. It is demonstrated that, by recording in absolute time the neutron detector events linked to an excitation, information can be resolved on sub-millisecond timescales. Specifically, the concept of the method is demonstrated by neutron reflectivity measurements in time-of-flight mode at the Liquids Reflectometer located at the Spallation Neutron Source, Oak Ridge National Laboratory, Tennessee, USA, combined with in situ rheometry. The opportunities and limitations of this new technique are evaluated by investigations of a micellar polymer solution offering excellent scattering contrast combined with high sensitivity to shear.

    Överlåtaren: a fast way to transfer and orthogonalize two-dimensional off-specular reflectivity data2016Inngår i: Journal of applied crystallography, ISSN 0021-8898, E-ISSN 1600-5767, Vol. 49, s. 2091-2099Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Reflectivity measurements offer unique opportunities for the study of surfaces and interfaces, and specular reflectometry has become a standard tool in materials science to resolve structures normal to the surface of a thin film. Off-specular scattering, which probes lateral structures, is more difficult to analyse, because the Fourier space being probed is highly anisotropic and the scattering pattern is truncated by the interface. As a result, scattering patterns collected with (especially time-of-flight) neutron reflectometers are difficult to transform into reciprocal space for comparison with model calculations. A program package is presented for a generic two-dimensional transformation of reflectometry data into q space and back. The data are represented on an orthogonal grid, allowing cuts along directions relevant for theoretical modelling. This treatment includes background subtraction as well as a full characterization of the resolution function. The method is optimized for computational performance using repeatable operations and standardized instrument settings.

    Determination of thermal hydraulic data of GHARR-1 under reactivity insertion transients using the PARET/ANL code2011Inngår i: Nuclear Engineering and Design, ISSN 0029-5493, E-ISSN 1872-759X, Vol. 241, s. 5303-5210Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The PARET/ANL code has been adapted by the IAEA for testing transient behaviour in research reactors since it provides a coupled thermal hydrodynamic and point kinetics capability for estimating thermalhydraulic margins. A two-channel power peaking profile of the Ghana Research Reactor-1 (GHARR-1) has been developed for the PARET/ANL (Version 7.3; 2007) using the Monte Carlo N-Particle code (MCNP) to determine the thermal hydraulic data for reactivity insertion transients in the range of 2.0×10^−3k/k to 5.5×10^−3k/k. Peak clad and coolant temperatures ranged from 59.18 ◦C to 112.36 ◦C and 42.95 ◦C to 79.42 ◦C respectively. Calculated safety margins (DNBR) satisfied the MNSR thermal hydraulic design criteria for which no boiling occurs in the reactor core. The generated thermal hydraulic data demonstrated a high inherent safety feature of GHARR-1 for which the high negative reactivity feedback of the moderator limits power excursion and consequently the escalation of the clad temperature.

    Aspects of Conformal Field theory2022Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Quantum field theories are very good at describing the world around us but use complicated computations that cannot always be solved exactly. Introducing conformal symmetry to quantum field theory can reduce this complexity and allow for quite simple calculation in the best case. This report aims to describe the critical part of the Ising model in 2 dimensions using conformal field theory while assuming only some knowledge of quantum mechanics and complex analysis from the reader. This is done by using the book Conformal Field Theory as the source for information about conformal field theory.

    Deterministic chaos and fractal entropy scaling in Floquet conformal field theories2021Inngår i: Physical Review B, ISSN 2469-9950, E-ISSN 2469-9969, Vol. 103, nr 10, artikkel-id L100302Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this Letter, we study two-dimensional Floquet conformal field theory, where the external periodic driving is described by iterated logistic or tent maps. These maps are known to be typical examples of dynamical systems exhibiting the order-chaos transition, and we show that, as a result of such driving, the entanglement entropy scaling develops fractal features when the corresponding dynamical system approaches the chaotic regime. For the driving set by the logistic map, the fractal contribution to the scaling dominates, making entanglement entropy a highly oscillating function of the subsystem size.

    Broadband and HF Radiation from Cloud Flashes and Narrow Bipolar Pulses2011Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Remote measurement of electric field generated by lightning has played a major role in understanding the lightning phenomenon. Even though other measurements such as photographic and channel base current have contributed to this research field, due to practical reasons remote measurements of electric field is considered as the most useful tool in lightning research.

    This thesis discusses the remotely measured radiation field component of electric field generated by cloud flashes (ICs) and narrow bipolar pulses (NBPs). The associated HF radiation of these events at 3 MHz and 30 MHz are also discussed. To understand the initiation process of these discharges, a comparative study of the initial pulse of cloud flashes against the initial pulse of cloud to ground flashes was conducted. The result suggests that both discharges might have been initiated by similar physical processes inside the thunderclouds. Comparing the features of initial pulse of cloud and ground flashes with that of pulses that appeared in the later stages of cloud flashes suggests that the initiation process involved in both flashes are not very much different from the initiation of cloud flashes at the later stage. The average spectral amplitudes of electric field of full duration cloud flashes (180 ms) showed -1 frequency dependence within the interval of 10 kHz to approximately 10 MHz. This is in contrast to the standard -2 decrement (or even steeper ) at high frequency region for other lightning processes such as return strokes. It was suggested that small pulses which repeatedly appeared at the later stage of cloud flashes might have contributed to enhance the spectral amplitude at higher frequencies.

    Electric fields generated by Narrow Bipolar Pulses (NBPs), which are considered as one of the strongest sources of HF radiation, were measured in the tropics of Malaysia and Sri Lanka.  Their features were also studied and show a good agreement with previously published observations of NBPs from other geographical regions. Thorough analyses and observations of these pulses found previously unreported sharp, fine peaks embedded in the rising and decaying edge of the electric field change of NBPs. Therefore it was suggested that these fine peaks are mostly responsible for the intense HF radiation at 30 MHz.

    Abstract [en]

    In this study, the first electric field pulse of cloud and cloud-to-ground discharges were analyzed and compared with other pulses of cloud discharges. Thirty eight cloud discharges and 101 cloud-to-ground discharges have been studied in this analysis. Pulses in cloud discharges were classified as [`]small', [`]medium' and [`]large', depending upon the value of their relative amplitude with respect to that of the average amplitude of the five largest pulses in the flash. We found that parameters, such as pulse duration, rise time, zero crossing time and full-width at half-maximum (FWHMs) of the first pulse of cloud and cloud-to-ground discharges are similar to small pulses that appear in the later stage of cloud discharges. Hence, we suggest that the mechanism of the first pulse of cloud and cloud-to-ground discharges and the mechanism of pulses at the later stage of cloud discharges could be the same.

    The radiation electric fields produced by long-duration cloud flashes have been Fourier analyzed to determined the frequency spectrum in the range of 10 kHz to 10 MHz. The flashes were recorded within a distance of less than 20 km. The spectrum was normalized to 50 km distance and it shows a f-1 dependence within the entire frequency range.

    Abstract [en]

    Narrow bipolar pulses (NBPs) are considered as isolated intracloud events with higher peak amplitude and strong high frequency emission compared to the first return strokes and other intracloud discharges. From 182 NBPs recorded in Malaysia in the tropic, 75 were narrow negative bipolar pulses (NNBPs) while 107 were narrow positive bipolar pulses (NPBPs). The mean duration of NNBPs was 24.6 +/- 17.1 mu s, while 30.2 +/- 12.3 mu s was observed for NPBPs. The mean full-width at half-maximum (FVVHM) was 2.2 +/- 0.7 and 2.4 +/- 1.4 mu s for NNBPs and NPBPs, respectively. The mean peak amplitude of NPBPs normalized to 100 km was 22.7 V/m, a factor of 1.3 higher than that of NNBPs which is 17.6 V/m. In contrast to the previous studies, it was observed that the electric field change was characterized by a bipolar pulse with a significant amount of fine structures separated by a few tens of nanoseconds intervals, embedded on it.

    Narrow Bipolar Pulses (NBPs) are generated by intra-cloud discharge processes and they are of interest due to their strong broadband and high frequency (HF) emissions. In this study, we present some features of electric field waveform of NBPs which have not been reported in the literature.  The HF emission was observed to begin simultaneously with the onset of NBPs indicating no streamers or stepped-leader process was taking place before the initiation of NBPs. The electric field waveforms of NBPs were characterized by many fine peaks embedded intermittently on the rising and decaying edge of NBPs suggesting that some small scale electrical discharges were involved during the formation of NBPs.

    Effective particle magnetic moment of multi-core particles2015Inngår i: Journal of Magnetism and Magnetic Materials, ISSN 0304-8853, E-ISSN 1873-4766, Vol. 380, s. 221-226Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study we investigate the magnetic behavior of magnetic multi-core particles and the differences in the magnetic properties of multi-core and single-core nanoparticles and correlate the results with the nanostructure of the different particles as determined from transmission electron microscopy (TEM). We also investigate how the effective particle magnetic moment is coupled to the individual moments of the single-domain nanocrystals by using different measurement techniques: DC magnetometry, AC susceptometry, dynamic light scattering and TEM. We have studied two magnetic multi-core particle systems BNF Starch from Micromod with a median particle diameter of 100 am and FeraSpin R from nanoPET with a median particle diameter of 70 nm - and one single-core particle system - SHP25 from Ocean NanoTech with a median particle core diameter of 25 nm.

    A Social Semiotic Approach to Teaching and Learning Science2018Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    A social semiotic approach to teaching and learning science.

    In this presentation I will discuss the application of social semiotics to the teaching and learning of university science. Science disciplines leverage a wide range of semiotic resources such as graphs, diagrams, mathematical representations, hands on work with apparatus, language, gestures etc. In my work I study how students learn to integrate these resources to do physics and what teachers can do to help them in this process. Over the years, a number of theoretical constructs have been developed within the Physics Education Research Group in Uppsala to help us to better understand the different roles semiotic resources play in learning university physics. In this presentation I will explain some of these terms and give examples of their usefulness for teasing out how learning is taking place.

    Disciplinary Affordance vs Pedagogical Affordance: Teaching the Multimodal Discourse of University Science2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Disciplinary Affordance vs Pedagogical Affordance: Teaching the

    Multimodal Discourse of University Science

    The natural sciences have been extremely successful in modeling some specific aspects

    of the world around us. This success is in no small part due to the creation of generally

    accepted, paradigmatic ways of representing the world through a range of semiotic

    resources. The discourse of science is of necessity multimodal (see for example Lemke,

    1998) and it is therefore important for undergraduate science students to learn to

    master this multimodal discourse (Airey & Linder, 2009). In this paper, I approach the

    teaching of multimodal science discourse via the concept of affordance.

    Since its introduction by Gibson (1979) the concept of affordance has been debated by a

    number of researchers. Most famous, perhaps is the disagreement between Gibson and

    Norman (1988) about whether affordances are inherent properties of objects or are

    only present when perceived by an organism. More recently, affordance has been

    drawn on in the educational arena, particularly with respect to multimodality (see

    Fredlund, 2015 for a recent example). Here, Kress et al (2001) have claimed that

    different modes have different specialized affordances.

    In the presentation the interrelated concepts of disciplinary affordance and pedagogical

    affordance will be presented. Both concepts make a radical break with the views of both

    Gibson and Norman in that rather than focusing on the perception of an individual, they

    refer to the disciplinary community as a whole. Disciplinary affordance is "the agreed

    meaning making functions that a semiotic resource fulfills for a disciplinary community".

    Similarly, pedagogical affordance is "the aptness of a semiotic resource for the teaching

    and learning of some particular educational content" (Airey, 2015). As such, in a

    teaching situation the question of whether these affordances are inherent or perceived

    becomes moot. Rather, the issue is the process through which students come to use

    semiotic resources in a way that is accepted within the discipline. In this characterization

    then, learning can be framed in terms of coming to perceive and leverage the

    disciplinary affordances of semiotic resources.

    In this paper, I will discuss: the disciplinary affordances of individual semiotic resources,

    how these affordances can be made “visible” to students and how the disciplinary

    affordances of semiotic resources are ultimately leveraged and coordinated in order to

    make science meanings.

    Abstract [sv]

    I detta kapitel läggs fram ett nytt begrepp, disciplinary literacy, som ett alternativ till scientific literacy. För varje ämne, disciplinary literacy inriktar sig mot kommunikativa praktiker inom tre miljöer: akademin, arbetsplatsen och samhället och definieras som förmågan att delta i dessa ämnesrelaterade kommunikativa praktiker på ett lämpligt sätt. Frågeställningen för kapitlet är om det kan vara givande att betrakta främjandet av studenters disciplinary literacy som ett av de huvudsakliga målen med universitetsstudier. Tillämpningen av begreppet illustreras genom material hämtat från ett forskningsprojekt där högskolelärare i fysik från Sverige och Sydafrika diskuterar de lärandemål de har för sina studenter.

    Learning and Sharing Disciplinary Knowledge: The Role of Representations2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Learning and Sharing Disciplinary Knowledge: The Role of Representations.

    Abstract

    In recent years there has been a large amount of interest in the roles that different representations (graphs, algebra, diagrams, sketches, physical models, gesture, etc.) play in student learning. In the literature two distinct but interrelated ways of thinking about such representations can be identified. The first tradition draws on the principles of constructivism emphasizing that students need to build knowledge for themselves. Here students are encouraged to create their own representations by working with materials of various kinds and it is in this hands-on representational process that students come to develop their understanding.

    The second tradition holds that there are a number of paradigmatic ways of representing disciplinary knowledge that have been created and refined over time. These paradigmatic disciplinary representations need to be mastered in order for students to be able to both understand and effectively communicate knowledge within a given discipline.

    In this session I would like to open up a discussion about how these two ways of viewing representations might be brought together. To do this I will first present some of the theoretical and empirical work we have been doing in Sweden over the last fifteen years. In particular there are three concepts that I would like to introduce for our discussion: critical constellations of representations, the disciplinary affordance of representations and the pedagogical affordance of representations.

    Representations in Undergraduate Physics2014Annet (Annet vitenskapelig)
    Abstract [en]

    Representations in undergraduate physics

    Problem solving is one of the most important parts of undergraduate physics education, yet a huge body of international research has clearly shown that simply being able to solve a set of physics problems correctly is not a good indicator of students having attained appropriate physics understanding. Grounded in a comparison of the way experts and novices solve problems, the research focus has gradually shifted towards the importance of representational competence in solving physics problems.Physicists use a wide range of representations to communicate physics knowledge (e.g. mathematics,  graphs, diagrams, and spoken and written language, etc.). Many of these representations are highly specialized and have been developed and refined into their present form over time. It is the appropriate coordination of these different representations that allows complex physics meanings to be made and shared. Experienced physicists naturally maintain coherence as they move from one representation to the next in order to solve a physics problem. For students, however, learning to appropriately use physics representations in this way is a challenging task. This lecture addresses the critical role that representations play in undergraduate physics education. The research that has been carried out in this area will be summarized and a number of theoretical constructs that have been developed in the Division of Physics Education Research will be presented and illustrated using empirical data. The consequences of this research work for the teaching and learning of undergraduate physics will be discussed.

    Abstract [en]

    This project compares the affordances and constraints for physics teachers’ professional identity building across four countries. The results of the study will be related to the potential consequences of this identity building for pupils’ science performance in school. The training of future physics teachers typically occurs across three environments, the physics department, the education department and school (during teaching practice). As they move through these three environments, trainees are in the process of building their professional identity. However, what is signalled as valuable for a future physics teacher differs considerably in different parts of the education. In educational research, professional identity has been used in a variety of ways (See for example overviews of the concept in Beauchamp & Thomas, 2009; and Beijaard, Meijer, & Verloop, 2004). In this project we draw on the work of Sfard and Pruzak (2005) who have defined identity as an analytical category for use in educational research. The project leverages this concept of identity as an analytical tool to understand how the value-systems present in teacher training environments and society as a whole potentially affect the future practice of trainee physics teachers. For identities to be recognized as professional they must fit into accepted discourses. Thus the project endeavours to identify discourse models that tacitly steer the professional identity formation of future physics teachers. Interviews will be carried out with trainee physics teachers and the various training staff that they meet during their education (physics lecturers, education lecturers, school mentors). It has been suggested that the perceived status of the teaching profession in society has a major bearing on the type of professional identity teachers can enact. Thus, in this project research interviews will be carried out in parallel across four countries with varying teacher status and PISA science scores: Sweden, Finland, Singapore and England. These interviews will be analysed following the design developed in a pilot study that has already carried out by the project group in Sweden. The research questions for the project are as follows: In four countries where the societal status of the teaching profession differs widely: What discourse models are enacted in the educational environments trainee physics teachers meet? What are the potential affordances and constraints of these discourse models for the constitution of physics teacher professional identities? In what ways do perceptions of the status assigned by society to the teaching profession potentially affect this professional identity building? What are the potential consequences of the answers to the above questions for the view of science communicated to pupils in school? In an extensive Swedish pilot study, four potentially competing discourse models were identified: these are: the critically reflective teacher, the practically well-equipped teacher, the syllabus implementer and the physics expert. Of these, the physics expert discourse model was found to dominate in both the physics department and amongst mentors in schools. In the physics expert discourse model the values of the discipline of physics dominate. Thus, the overarching goal of physics teaching is to create future physicists. In this model, the latest research in physics is seen as interesting and motivating, whereas secondary school subject matter is viewed as inherently unsophisticated and boring—something that needs to be made interesting. The model co-exists with the three other discourse models, which were more likely to be enacted in the education department. These other models value quite different goals such as the development of practical skills, reflective practice, critical thinking and citizenship. We claim that knowledge of the different discourse models at work in four countries with quite different outcomes on PISA science will useful in a number of ways. For teacher trainers, a better understanding of these models would allow informed decisions to be taken about the coordination of teacher education. For prospective teachers, knowledge of the discourse models at work during their education empowers them to question the kind of teacher they want to become.

    Abstract

    In this research project we focused on the different semiotic resources used in physics (e.g. graphs, diagrams, language, mathematics, apparatus, etc.). We were interested in the ways in which undergraduate physics students learn to combine the different resources used in physics in order to become “disciplinary literate” and what university lecturers do to help their students in this process. Comparative data on the disciplinary literacy goals of physics lecturers for their students was collected at five universities in South Africa and four universities in Sweden.

    One of the main contributions of the project concerned what we termed the disciplinary affordance of a semiotic resource, that is, the specific meaning-making functions a particular resource plays for the discipline. We contrasted these meaning-making functions with the way that students initially viewed the same resource.

    We proposed two ways that lecturers can direct their students’ attention towards the disciplinary affordances of a given resource. The first involves unpacking the disciplinary affordance in order to create a new resource with higher pedagogical affordance. Our second proposal involved the use of systematic variation in order to help students notice the disciplinary relevant aspects of a given resource. A total of 19 articles/book chapters were published as a direct result of this funding.

    Abstract [en]

    Social semiotics is a broad construct where all communication in a particular social group is viewed as being realized by the use of semiotic resources. In social semiotics the particular meaning assigned to these semiotic resources is negotiated within the group itself and has often developed over an extended period of time. In the discipline of physics, examples of such semiotic resources are; graphs, diagrams, mathematics, language, etc. 

    In this presentation, social semiotics is used to build theory with respect to the construction and sharing of disciplinary knowledge in the teaching and learning of university physics. Based on empirical studies of physics students, a number of theoretical constructs have been developed in our research group. These constructs are: disciplinary affordance, disciplinary discourse, discursive fluency, discourse imitation and critical constellations. I will present these constructs and examine their usefulness for problematizing teaching and learning with multiple representations in higher education.

    The Concept of Affordance in Teaching and Learning Undergraduate Science

    Since its introduction by Gibson (1979)the concept of affordance has been debated by a number of researchers. Most famous, perhaps is the disagreement between Gibson and Norman(1988)about whether affordances are inherent properties of objects or are only present when perceived by an organism. More recently, affordance has been drawn on in the educational arena, particularly with respect to multimodality (see Fredlund, 2015 for a recent example). 

    In the presentation the interrelated concepts of disciplinary affordance and pedagogical affordance will be presented. Both concepts make a radical break with the views of both Gibson and Norman in that rather than focusing on the perception of an individual, they refer to the disciplinary community as a whole. Disciplinary affordance is "the agreed meaning making functions that a semiotic resource fulfills for a disciplinary community". Similarly, pedagogical affordance is "the aptness of a semiotic resource for the teaching and learning of some particular educational content" (Airey, 2015). As such, in a teaching situation the question of whether these affordances are inherent or perceived becomes moot. Rather, the issue is the process through which students come to use semiotic resources in a way that is accepted within the discipline. In this characterization then, learning can be framed in terms of coming to perceive and leverage the disciplinary affordances of semiotic resources.

    Undergraduate Teaching and Learning in English2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In this presentation I discuss the use of English in the teaching and learning of undergraduate physics. Research is presented on what happens when students change to learning in English and what happens when university lecturers change to teaching in English. The presentation concludes by suggesting that the use of English in any given course or programme should be pedagogically motvated and that this should be set out in the learning outcomes of the syllabus. This suggests that physics courses taught in the meduim of English should have language learning outcomes. This in turn suggests that these outcomes should be both taught and tested as part of the course.

    Undergraduate Teaching with Multiple Semiotic Resources: Disciplinary Affordance vs Pedagogical Affordance2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Since its introduction by Gibson (1979) the concept of affordance has been discussed at length by a number of researchers. Most famous, perhaps is the disagreement between Gibson and Norman (1988) about whether affordances are inherent properties of objects or are only present when perceived by an organism. More recently, affordance has been drawn on in the educational arena, particularly with respect to multimodality (see Fredlund et al 2015 for a recent example). Here, Kress et al (2001) have claimed that different modes have different specialized affordances. In this paper the interrelated concepts of disciplinary affordance and pedagogical affordance are discussed. Both concepts make a radical break with the views of both Gibson and Norman in that rather than focusing on the perception of an individual, they refer to the disciplinary community as a whole. Disciplinary affordance is "the agreed meaning making functions that a semiotic resource fulfils for a disciplinary community". Similarly, pedagogical affordance is "the aptness of a semiotic resource for the teaching and learning of some particular educational content" (Airey 2015). As such, the question of whether these affordances are inherent or perceived becomes moot. Rather, the issue is the process through which students can come to see semiotic resources in a way that corresponds to the disciplinary affordance accepted within the discipline. The power of the term, then, is that learning can now be framed as coming to perceive the disciplinary affordances of semiotic resources. In this paper I will briefly discuss the history of the term affordance, define the terms disciplinary affordance and pedagogical affordance and illustrate their usefulness in a number of educational settings.

    Using variation and unpacking to help students decode disciplinary-specific semiotic resources2018Inngår i: 9ICOM - Complete book of abstracts, Odense, Denmark.: Syddansk Universitet, 2018Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In this presentation I will describe a social semiotic approach (Halliday 1978; van Leeuwen 2005) to the multimodal teaching and learning of a discipline that takes variation theory (Marton & Booth 1997; Runesson 2005) as its theoretical framing. Following Airey and Linder (2017:95) I define social semiotics as “the study of the development and reproduction of specialized systems of meaning making in particular sections of society”

     

    Learning at university level involves coming to understand the ways in which disciplinary-specific semiotic resources can be coordinated to make appropriate disciplinary meanings (Airey & Linder 2009). Nowhere is this more true than in undergraduate physics where a particularly wide range of semiotic resources such as graphs, diagrams, mathematics and language are essential for meaning making.  In order to learn to make these disciplinary meanings, students need to discover the disciplinary affordances(Fredlund et al. 2012, 2014; Airey & Linder 2017) of the semiotic resources used in their discipline. 

     

    Fredlund et al. (2015) propose a three-stage process that lecturers can use to help their students:  

     

    1. Identify the disciplinary relevant aspects needed for a particular task. 

    2. Select semiotic resources that showcase these aspects. 

    3. Create structured variation within these semiotic resources to help students notice the disciplinary relevant aspects and their relationships to each other.

     

    However, many disciplinary specific semiotic resources have been rationalized to create a kind of disciplinary shorthand(Airey 2009). In such cases the disciplinary relevant aspects needed may no longer be present in resources used, but are rather implied. In such cases the resources will need to be unpacked for students (Fredlund et al. 2014).  Such unpacking increases the pedagogical affordance of semiotic resources but simultaneously decreases their disciplinary affordance.

    That's Funny!: The humorous effect of misappropriating  disciplinary-specific semiotic resources2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The socialization of disciplinary outsiders into an academic discipline has been described both in terms of becoming fluent in a disciplinary discourse (Airey, 2009; Airey & Linder, 2009; Northedge, 2002) and achieving disciplinary literacy (Airey, 2011, 2013; Geisler, 1994). In this paper we investigate disciplinary boundaries by documenting the responses of academics to a semiotic disciplinary hybrid. The hybrid we use is the Physikalisches Lied, a bogus piece of sheet music into which disciplinary-specific semiotic resources from the realm of physics have been incorporated to humorous effect.

    The piece is presented to three distinct disciplinary focus groups: physicists, musicians and a group of academics who have had little contact with either discipline. In order to elicit disciplinary responses that are free from researcher prompts, each focus group is first asked the simple, open-ended question What do you see here? Once discussion of this question is exhausted the focus groups are asked to identify as many puns as they can—essentially all the disciplinary items that they feel have been misappropriated—and to attempt to explain what this means from a disciplinary standpoint. The differences in the responses of the three groups are presented and analysed.

    We argue that semiotic material focused on by each of the three groups and the nature of the explanation offered, provide evidence of the degree of integration into the disciplines of physics and music. Our findings shed light on the process of becoming a disciplinary insider and the semiotic work involved in this process.

    Unpacking the Hertzsprung-Russell Diagram: A Social Semiotic Analysis of the Disciplinary and Pedagogical Affordances of a Central Resource in Astronomy2019Inngår i: Designs for Learning, ISSN 1654-7608, Vol. 11, nr 1, s. 99-107Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper we are interested in the relationship between disciplinary knowledge and its representation. We carry out a social semiotic analysis of a central tool used in astronomy—the Hertzsprung-Russell (H-R) diagram—in order to highlight its disciplinary and pedagogical affordances. The H-R diagram that we know today combines many layers of astronomical knowledge, whilst still retaining some rather quirky traces of its historical roots. Our analysis shows how these ‘layers of knowledge’ and ‘historical anomalies’ have resulted in a number of counterintuitive aspects within the diagram that have successively lowered its pedagogical affordance. We claim that these counterintuitive aspects give rise to potential barriers to student disciplinary learning. Using our analysis as a case study, we generalise our findings, suggesting four types of barrier to understanding that are potentially at work when students meet disciplinary-specific semiotic resources for the first time. We finish the paper by making some general suggestions about the wider use of our analysis method and ways of dealing with any barriers to learning identified. In the specific case of the H-R diagram, we suggest that lecturers should explicitly tease out its disciplinary affordances by the use of ‘unpacked’ resources that have a higher pedagogical affordance.

    On the Disciplinary Affordances of Semiotic Resources2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the late 70’s Gibson (1979) introduced the concept of affordance. Initially framed around the needs of an organism in its environment, over the years the term has been appropriated and debated at length by a number of researchers in various fields. Most famous, perhaps is the disagreement between Gibson and Norman (1988) about whether affordances are inherent properties of objects or are only present when they are perceived by an organism. More recently, affordance has been drawn on in the educational arena, particularly with respect to multimodality (see Linder (2013) for a recent example). Here, Kress et al. (2001) have claimed that different modes have different specialized affordances. Then, building on this idea, Airey and Linder (2009) suggested that there is a critical constellation of modes that students need to achieve fluency in before they can experience a concept in an appropriate disciplinary manner. Later, Airey (2009) nuanced this claim, shifting the focus from the modes themselves to a critical constellation of semiotic resources, thus acknowledging that different semiotic resources within a mode often have different affordances (e.g. two or more diagrams may form the critical constellation).

    In this theoretical paper the concept of disciplinary affordance (Fredlund et al., 2012) is suggested as a useful analytical tool for use in education. The concept makes a radical break with the views of both Gibson and Norman in that rather than focusing on the discernment of one individual, it refers to the disciplinary community as a whole. Put simply, the disciplinary affordances of a given semiotic resource are determined by those functions that the resource is expected to fulfil by the disciplinary community. Disciplinary affordances have thus been negotiated and developed within the discipline over time. As such, the question of whether these affordances are inherent or discerned becomes moot. Rather, from an educational perspective the issue is whether the meaning that a semiotic resource affords to an individual matches the disciplinary affordance assigned by the community. The power of the term for educational work is that learning can now be framed as coming to discern the disciplinary affordances of semiotic resources.

    In this paper we will briefly discuss the history of the term affordance, define the term disciplinary affordance and illustrate its usefulness in a number of educational settings.

    What does it mean to understand a physics Equation?   A study of Undergraduate answers In Three countries.

    In this paper we are interested in how undergraduate students in the US, Australia and Sweden experience the physics equations they meet in their education. We asked over 350 students the same simple question: How do you know when you understand a physics equation? Students wrote free-text answers to this question and these were transcribed and coded. The analysis resulted in eight themes (significance, origin, describe, predict, parts, relationships, calculate and explain). Each of these themes represents a different disciplinary aspect of student understanding of physics equations. We argue that together the different aspects we find represent a more holistic view of physics equations that we would like all our students to experience. Based on this work we wondered how best to highlight this more holistic view of equations. This prompted us to write a set of questions that reflect the original data with respect to the eight themes. We suggest that when students are working with problem solving they may ask themselves these questions in order to check their holistic understanding of what the physics equations they are using represent. In continuing work we are asking the same question to a cohort of physics lecturers. We are also trialling the themes and related questions that we generated in teaching situations. Here we are interested in whether students perceive the questions as helpful in their learning.

    Background

    As a discipline, physics is concerned with describing the world by constructing models, the end product of this modelling process often being an equation. Despite their importance in the representation of physics knowledge, physics equations have received surprisingly little attention in the literature. The work that has been done has tended to focus on the use of equations in problem solving (see Hsu, Brewe, Foster, & Harper, 2004 for an overview and Hegde & Meera, 2012 for a more recent example). One significant study is that of Sherin (2001) who examined students ability to construct equations. The majority of work suggests that many students in calculus-based physics courses focus their attention exclusively on selecting an equation and substituting in known values—so called “plug and chug” (see Tuminaro 2004). This behaviour—what Redish (1994) has termed the “Dead Leaves” approach to physics equations—has been framed as a major hurdle to students’ ability to see the bigger picture of physics. However, very little work has examined what students think it means to understand a physics equation, the only work we could locate was that of Domert et al, 2007 and Hechter, 2010. Building on these two sources this study examines student understanding of physics equations in three countries. Our research questions are:

    1. How do students in three countries say they know that they have understood a physics equation?
    2. What different disciplinary aspects of equations can be seen in an analysis of the complete set of answers to research question 1?
    3. How might a more holistic view of the understanding of equations be communicated to students?

    Method

    This qualitative study uses a research design based on minimum input and maximised output. We asked students in the US (n=83), Australia (n=168) and Sweden (n=105) the same simple question:

    How do you know when you understand a physics equation?

    Students wrote free-text answers to this question and these were transcribed and coded. Using qualitative analysis techniques drawn from the phenomenographic tradition, the whole dataset was then treated as a “pool of meaning” (See Airey, 2012 for an example of this type of analysis).

    Analysis and Results

    In our analysis we initially looked for differences across countries, however it quickly became apparent that there was a range of answers that repeated across countries. This led us to treat the data as a single set. This first analysis resulted in 15 preliminary categories. These categories were later broken up and reconstructed to form eight themes: Significance, Origin, Describe, Predict, Parts, Relationships, Calculate and Explain. We suggest that each of these eight themes represents a different disciplinary aspect of the expressed student understanding of physics equations. We argue that together the different aspects we find represent a more holistic view of physics equations that we would like all our students to experience. Based on this work we wondered how best to highlight this more holistic view of equations. This prompted us to write a set of questions that reflect the original data with respect to the eight themes:

    1      Significance: Why, when, where

    Do you know why the equation is needed?

    Do you know where the equation can and cannot be used? (boundary conditions/areas of physics).

    Do you understand what the equation means for its area of physics?

    What status does this equation have in physics? (fundamental law, empirical approximation, mathematical conversion, etc.).

    2      Origin

    Do you know the historical roots of the equation?

    Can you derive the equation?

    3      Describe/visualize

    Can you use the equation to describe a real-life situation?

    Can you describe an experiment that the equation models?

    Can you visualize the equation by drawing diagrams, graphs etc.

    4      Predict

    Can you use the equation to predict?

    5      Parts

    Can you describe the physical meaning of each of the components of the equation?

    How does a change in one component affect other components in the equation?

    Can you manipulate/rearrange the equation?

    6      Other equations

    Can you relate this equation to other equations you know?

    Can you construct the equation from other equations that you know?

    7      Calculate

    Can you use the equation to solve a physics problem?

    Can you use the equation to solve a physics problem in a different context than the one in which it was presented?

    When you use the equation to calculate an answer do you know:

    • How your answer relates to the original variables?
    • The physical meaning of this answer?
    • Whether your answer is reasonable?

    8      Explain

    Can you explain the equation to someone else?

    Discussion and conclusion

    The motivation for this study came from an experience the first author had a number of years ago. In an interview situation, students were asked in passing about whether they understood a certain equation. They replied “yes” and that the equation was “trivial”. However when questioned about what one of the terms in the equation meant and the students did not know! The students clearly meant that the equation was trivial from a mathematical point of view—they knew they could easily use the equation to “calculate stuff” so they said that they understood it. In Redish’s (1994) terms they were using the “Dead Leaves” approach to physics equations.

    We believe the questions we have generated in this study have the potential to help physics students who think they understand a physics equation to check whether there might be other aspects that they may not yet have considered.

    Our questions are based on student-generated data. Potentially physics lecturers could experience physics equations in even more complex ways. In continuing work we are therefore asking the same question to a cohort of physics lecturers. We are also trialling the themes and related questions that we generated in various teaching situations. Here we are interested in whether students perceive the questions as helpful in their learning.

    Abstract [en]

    In this chapter we are interested in how undergraduate physics students in three countries experience the equations they meet in their education. We asked over 350 students in the US, Australia and Sweden the same simple question: How do you know when you understand a physics equation? Students wrote free-text answers to this question and these were transcribed and coded. The similarity of the answers we received across the three countries surprised us and led to us treating all the answers as a single “pool of meaning”. Qualitative analysis resulted in eight distinct themes: significance, origin, description, prediction, parts, relationships, calculation and explanation. Drawing on diSessa’s theory of knowledge in pieces, we argue that each theme represents a different disciplinary aspect of student understanding of physics equations. Educationally, we wondered how best to highlight the more holistic view of equations that analysis of the combined datasets revealed. This prompted us to write a set of questions that reflect the original data with respect to the eight themes. We suggest that when students meet a new physics equation they may ask themselves these questions in order to check their holistic understanding of what the equation represents. In continuing work we are asking our same original question to a cohort of physics lecturers in order to consolidate the themes we have already identified and to look for further themes. We are also trialling the themes and related questions that we generated in teaching situations. Here, we are interested in whether students perceive the questions as helpful in their learning.

    Developing Students’ Disciplinary Literacy?: The Case of University Physics2018Inngår i: Global Developments in Literacy Research for Science Education / [ed] Kok-Sing Tang, Kristina Danielsson, Cham, Switzerland: Springer, 2018, s. 357-376Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    The main data set used in this chapter comes from a comparative study of physics

    lecturers in Sweden and South Africa. (Airey 2012; 2013: Linder et al 2014). Semistructured

    interviews were carried out using a disciplinary literacy discussion matrix

    (Airey 2011b), which enabled us to probe the lecturers’ disciplinary literacy goals in the

    various semiotic resource systems used in undergraduate physics (i.e. graphs, diagrams,

    mathematics, language, etc.).

    The findings suggest that whilst physics lecturers have strikingly similar

    disciplinary literacy goals for their students, regardless of setting; they have very different

    ideas about whether they themselves should teach students to handle these disciplinaryspecific

    semiotic resources. It is suggested that the similarity in physics

    lecturers’disciplinary literacy goals across highly disparate settings may be related to the

    hierarchical, singular nature of the discipline of physics (Bernstein 1999; 2000).

    In the final section of the chapter some preliminary evidence about the disciplinary

    literacy goals of those involved in physics teacher training is presented. Using Bernstein’s

    constructs, a potential conflict between the hierarchical singular of physics and the

    horizontal region of teacher training is noticeable.

    Going forward it would be interesting to apply the concept of disciplinary literacy

    to the analysis of other disciplines—particularly those with different combinations of

    Bernstein’s classifications of hierarchical/horizontal and singular/region.

    What Knowledge Do Trainee Physics Teachers Need to Learn?: Differences in the Views of Training Staff2014Inngår i: International Science Education Conference 2014 Programme, Singapore: Ministry of Education, National Institute of Education , 2014, s. 62-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Although the impact of disciplinary differences on teaching and learning has been extensively discussed in the literature (e.g. Becher 1989; Becher and Trowler 2001; Lindblom-Ylännea et al. 2006; Neumann 2001; Neumann and Becher 2002), little research has explored this issue in relation to teacher training. In particular, we know of no work that examines differing views about the knowledge that trainee teachers need to learn across different settings. In this paper we analyse differences in the expressed views of staff involved in the training of prospective physics teachers in three environments: the education department, the physics department and schools. We analyse these differences in terms of two constructs: disciplinary literacy goals (Airey 2011, 2013) and disciplinary knowledge structures (Bernstein 1999).

    In terms of disciplinary literacy we find a stronger emphasis on learning goals for the academy expressed by informants from the physics and education departments. This can be contrasted with the view that the needs of the workplace are paramount expressed by school practitioners.

    Then, using Bernstein’s knowledge structures, we also identify clear differences in views about the nature of knowledge itself with a more hierarchical view of knowledge prevalent in the physics department and the more horizontal view of knowledge prevalent in the education department.

    The study highlights the often-conflicting signals about what constitutes useful knowledge that prospective physics teachers need to negotiate during their training. We tentatively suggest that more attention should be paid to both the theory/practice divide and potential epistemological differences in the training of prospective teachers.

    Investigating Undergraduate Physics Lecturers’ Disciplinary Literacy Goals For Their Students2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Investigating Undergraduate Physics Lecturers’ disciplinary literacy Goals for their students.

    Abstract

     In this presentation we use the concept of disciplinary literacy (Airey, 2011a; 2013) to analyse the expressed learning goals of university physics lecturers for their students. We define disciplinary literacy in terms of learning to control a particular set of multimodal communicative practices. We believe it is important to document the expressed intentions of lecturers in this way, since it has previously been suggested that the development of such disciplinary literacy may be seen as one of the primary goals of university studies (Airey, 2011a).

    The main data set used in this presentation comes from a comparative study of 30 physics lecturers from Sweden and South Africa. (Airey, 2012, 2013; Linder et al, 2014). Semi-structured interviews were carried out using a disciplinary literacy discussion matrix (Airey, 2011b), which enabled us to probe the lecturers’ disciplinary literacy goals in the various semiotic resource systems used in undergraduate physics (e.g. graphs, diagrams, mathematics, spoken and written languages, etc.).

    The findings suggest that physics lecturers in both countries have strikingly similar disciplinary literacy goals for their students and hold similar beliefs about disciplinary semiotic resources. The lecturers also agree that teaching disciplinary literacy ought not to be their job. Here though, there were differences in whether the lecturers teach students to handle disciplinary-specific semiotic resources. These differences appear to be based on individual decisions, rather than being specific to a particular country or institution.

    Keywords: Higher education, Scientific literacy, Representations.

    Introduction: disciplinary literacy

    In this presentation we examine the notion of disciplinary literacy in university physics (see Airey, 2011a, 2011b, 2013 and the extensive overview in Moje, 2007). Drawing on the work of Gee (1991), Airey (2001a) has broadened the definition of literacy to include semiotic resource systems other than language, defining disciplinary literacy as:

    The ability to appropriately participate in the communicative practices of a discipline.

    He goes on to suggest that the development of disciplinary literacy may be seen as one of the primary goals of university studies. In this study we use this disciplinary literacy concept to compare and problematize the goals of undergraduate physics lecturers in Sweden and South Africa.

    Research questions

    Our research questions for this study are:

    1. What do physics lecturers at universities in Sweden and South Africa say about disciplinary literacy in terms of the range of semiotic resources they want their students to learn to master?
    2. To what extent do these physics lecturers say that they themselves take responsibility for the development of this disciplinary literacy in their students?

    Data Collection

    The data set used for this presentation is taken from a comparative research project where 30 university physics lecturers from a total of nine universities in Sweden (4) and South Africa (5) described the disciplinary literacy goals they have for their students (Airey, 2012, 2013; Linder et al, 2014). A disciplinary literacy discussion matrix (Airey, 2011b) was used as the basis for in-depth, semi-structured interviews.

    These were conducted in English and lasted approximately 60 minutes each. In the interviews the lecturers were encouraged to talk about the semiotic resources they think their students need to learn to control.

    Analysis

    The analysis drew on ideas from the phenomenographic research tradition by treating the interview transcripts as a single data set or “pool of meaning” (Marton & Booth, 1997: 133). The aim was to understand the expressed disciplinary literacy goals of the physics lecturers interviewed. Following the approach to qualitative data analysis advocated by Bogdan and Biklen (1992), iterative cycles were made through the data looking for patterns and key statements. Each cycle resulted in loosely labeled categories that were often split up, renamed or amalgamated in the next iteration. More background and details of the approach used can be found in Airey (2012).

    Results and Discussion

    Analysis of the 30 interviews resulted in the identification of four themes with respect to the lecturers’ disciplinary literacy goals:

    1. Teaching physics is not the same thing as developing students’ disciplinary literacy.

    All the lecturers expressed a strong commitment that physics is independent of the semiotic resources used to construct it. For them, developing disciplinary literacy and teaching physics were quite separate things.

    These are tools, physics is something else. Physics is more than the sum of these tools it’s the way physicists think about things—a shared reference of how to analyse things around you.

    This theme challenges contemporary thinking in education and linguistics. Halliday and Martin (1993, p. 9) for example insist that communicative practices are not some sort of passive reflection of a priori disciplinary knowledge, but rather are actively engaged in bringing knowledge into being. In science education, an even more radical stance has been taken by Wickman and Östman (2002), who insist that disciplinary learning itself should be viewed as a form of discourse change.

    1. Disciplinary literacy in a range of semiotic resources is necessary for learning physics.

    All the lecturers in the study felt it was desirable that students develop disciplinary literacy in a range of semiotic resources in order to cope with their studies. In many ways this finding is unremarkable, with a number of researchers having commented on the wide range of semiotic systems needed for appropriate knowledge construction and communication in physics (e.g. Airey, 2009; Lemke, 1998; McDermott, 1990; Parodi, 2012).

    1. Developing disciplinary literacy is not really the job of a physics teacher.

    All physics lecturers expressed frustration at the low levels of disciplinary literacy in their students, feeling that they really should not have to work with the development of these skills, e.g.:

    I cannot say that I test them or train them in English. Of course they can always come and ask me, but I don’t think that I take responsibility for training them in English

    Northedge (2002) holds that the role of a university lecturer should be one of a discourse guide leading “excursions” into disciplinary discourse. However, although some lecturers actually did in fact work in this way (see category 4) the none of physics lecturers interviewed in this study felt comfortable with this role.

    1. Some teachers were prepared to take responsibility for the development of certain aspects of students’ disciplinary literacy.

    Nonetheless, some physics lecturers did say that the development of students’ disciplinary literacy would be something that they would work with. In these cases, lecturers (somewhat grudgingly) took on Northedge’s (2002) role of a discourse guide. This position was most common for mathematics, which was seen as essential for an understanding of physics (see Airey, 2012. p. 75 for further discussion of this theme).

    To be able to express it in a precise enough way you need mathematics. Language is more limited than mathematics in this case. So they need to use mathematics to see physics rather than language.

     

    Conclusion

    In this presentation we have applied the concept of disciplinary literacy to the goals of university physics lecturers. Lecturers reported their belief that disciplinary literacy in a wide range of semiotic resources is a necessary condition for physics learning. However, the same lecturers do not feel the development of this disciplinary literacy is their job. Although some lecturers were prepared to help students develop specific aspects of disciplinary literacy, all the lecturers interviewed believed that teaching physics is something that is separate from teaching disciplinary literacy. Here, Airey has argued that:

    Until lecturers see their role as one of socialising students into the discourse of their discipline…[they] will continue to insist that they are not [teachers of disciplinary literacy] and that this should be a job for someone else.                                                                                                                        (Airey, 2011b, p. 50)

    Abstract

    Over a decade has passed since Northedge (2002) convincingly argued that the role of the university lecturer should be viewed as one of leading students on excursions into the specialist discourse of their field. In his view, disciplinary discourses have come into being in order to create and share disciplinary knowledge that could not otherwise be appropriately construed in everyday discourse. Thus, Northedge’s conclusion is that in order for disciplinary learning to occur, students will need explicit guidance in accessing and using the specialist discourse of their chosen field. Building on this work, Airey (in press) argues that all university lecturers are, at least to some extent, teachers of language—even in monolingual settings. A radical approach to this claim has been suggested by Wickman and Östman (2002) who insist that learning itself be treated as a form of discourse change.

    In an attempt to operationalise Wickman and Östman’s assertion, Airey (2011b) suggests that the goals of any undergraduate degree programme may be framed in terms of the development of disciplinary literacy. Here, disciplinary literacy is defined as the ability to appropriately participate in the communicative practices of a discipline. Further, in his subsequent work, Airey (2011a) claims that all disciplines attempt to meet the needs of three specific sites: the academy, the workplace and society. He argues that the relative emphasis placed on teaching for these three sites will be different from discipline to discipline and will indeed vary within a discipline depending on the setting. In the South African setting two questions arise from this assertion. The first is: For any given discipline, what particular balance between teaching for the academy, the workplace and society is desirable and/or practicable? The second question follows on from the first: Having pragmatically decided on the teaching balance between the academy, workplace and society, what consequences does the decision have for the language(s) that lecturers should be helping their students to interpret and use? In order to address these two questions we conducted an interview-based case study of the disciplinary literacy goals of South African university lecturers in one particular discipline (physics). Thus, our overarching research question is as follows: How do South African physics lecturers problematise the development of disciplinary literacy in their students?

    The data collected forms part of a larger international comparative study of the disciplinary literacy goals of physics lecturers in Sweden and South Africa. A disciplinary literacy discussion matrix (Airey, 2011a) was employed as the starting point for conducting in-depth, semi-structured interviews with 20 physics lecturers from five South African universities. The choice of these five universities was purposeful—their student cohorts encompassing a range of different first languages and cultural backgrounds. The interviews were conducted in English, lasted between 30 and 60 minutes, and were later transcribed verbatim. The transcripts were then analysed qualitatively. This involved “working with data, organizing it, breaking it into manageable units, synthesizing it, searching for patterns, discovering what is important and what is to be learned, and deciding what you will tell others” (Bogdan & Biklen, 1992:145).

    The main finding of this study is that all the lecturers mentioned language as being problematic in some way. However, there were a number of important differences in the ways the lecturers problematise the development of disciplinary literacy both across and within the different university physics departments. These differences can be seen to involve on the one hand, the lecturers’ own self-image in terms of whether they are comfortable with viewing themselves as language teachers/literacy developers, and on the other hand, their recognition of the diverse linguistic and cultural backgrounds of their students. The differences will be illustrated and discussed using transcript excerpts. These findings are in contrast to parallel data collected in Sweden. In that particular (bilingual) setting, language was viewed as unproblematic, and the most striking characteristic was the very similarity of the responses of physics lecturers (Airey, in press). It is thus suggested that the differences in findings between Sweden and South Africa are a product of the latter’s diverse multilingual and multicultural environment. One pedagogical conclusion is that, given the differences in approach we find, inter- and intra faculty discussions about undergraduate disciplinary literacy goals would appear to have the distinct potential for reforming undergraduate physics. Similarly, an administrative conclusion is that a one-size-fits-all language policy for universities does not appear to be meaningful in such a diverse multilingual/multicultural environment.

    Finally, it should be mentioned that our choice of physics as an exemplar in this study has important implications for the interpretation of the findings. Drawing on Bernstein (1999), Martin (2011) suggests that disciplines have predominantly horizontal or hierarchical knowledge structures. Here it is claimed that physics has the most hierarchical knowledge structure of all disciplines. Thus, the findings presented here should be taken as illustrative of the situation in disciplines with more hierarchical knowledge structures (such as the natural and applied sciences). Kuteeva and Airey (in review) find that the issue of the language of instruction in such disciplines is viewed as much less problematic than in disciplines with more horizontal knowledge structures (such as the arts, humanities and, to some extent, social sciences). See Bennett (2010) for a provocative discussion of language use in such disciplines.

    A Disciplinary Discourse Perspective on University Science Learning: Achieving fluency in a critical constellation of modes2008Inngår i: Journal of Research in Science Teaching, ISSN 0022-4308, E-ISSN 1098-2736, Vol. 46, nr 1, s. 27-49Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this theoretical article we use an interpretative study with physics undergraduates to exemplify a proposed characterization of student learning in university science in terms of fluency in disciplinary discourse. Drawing on ideas from a number of different sources in the literature, we characterize what we call “disciplinary discourse” as the complex of representations, tools and activities of a discipline, describing how it can be seen as being made up of various “modes”. For university science, examples of these modes are: spoken and written language, mathematics, gesture, images (including pictures, graphs and diagrams), tools (such as experimental apparatus and measurement equipment) and activities (such as ways of working—both practice and praxis, analytical routines, actions, etc.). Using physics as an illustrative example, we discuss the relationship between the ways of knowing that constitute a discipline and the modes of disciplinary discourse used to represent this knowing. The data comes from stimulated recall interviews where physics undergraduates discuss their learning experiences during lectures. These interviews are used to anecdotally illustrate our proposed characterization of learning and its associated theoretical constructs. Students describe a repetitive practice aspect to their learning, which we suggest is necessary for achieving fluency in the various modes of disciplinary discourse. Here we found instances of discourse imitation, where students are seemingly fluent in one or more modes of disciplinary discourse without having related this to a teacher-intended disciplinary way of knowing. The examples lead to the suggestion that fluency in a critical constellation of modes of disciplinary discourse may be a necessary (though not always sufficient) condition for gaining meaningful holistic access to disciplinary ways of knowing. One implication is that in order to be effective, science teachers need to know which modes are critical for an understanding of the material they wish to teach.
