Background and purpose : Knowing how students learn physics is a central goal of physics education. The major purpose of this study is to examine the strength of the predictive power of students’ epistemic views and conceptions of learning in terms of their approaches to learning in physics. Sample, design and method : A total of 279 Taiwanese high school students ranging from 15 to 18?years old participated in this study. Three questionnaires for assessing high school students’ epistemic views on physics, conceptions of learning physics and approaches to learning physics were developed. Step-wise regression was performed to examine the predictive power of epistemic views on physics and conceptions of learning physics in terms of their approaches to learning physics. Results and conclusion: The results indicated that, in general, compared to epistemic views on physics, conceptions of learning physics are more powerful in predicting students’ approaches to learning physics in light of the regression models. That is, students’ beliefs about learning, compared with their beliefs about knowledge, may be more associated with their learning approaches. Moreover, this study revealed that the higher-level conceptions of learning physics such as ‘Seeing in a new way’ were more likely to be positively correlated with the deep approaches to learning physics, whereas the lower-level conceptions such as ‘Testing’ were more likely to positively explain the surface approaches, as well as to negatively predict the deep approaches to learning physics. 相似文献

This article explores what it can mean to be a woman physics student. A case study approach is used to explore how five women who are studying physics at a Swedish university simultaneously negotiate their doing of physics and their doing of gender. By conceptualising both gender and learning as aspects of identity formation, the analysis of the interviews with the five women offers insights into the nuances and complexities of how women relate to the gendered disciplinary culture of physics. This contrasts how research on gender and physics education has been predominantly concerned with comparisons of female and male students' attitudes and/or achievements. Furthermore, the analysis brings to the fore how it is not just the masculine connotations of physics that shape the experiences of the five women, but also the expectations on female physics students. 相似文献

This year’s Nobel Prize in physics recognises the spectacular progress during the last decade in the cooling and trapping of atoms by the use of laser beams. The techniques exploit basic physical principles with great ingenuity and have very interesting applications in precision measurement and the study of new phenomena. 相似文献

Students enter physics classes with negative attitudes towards physics compared to the other sciences. Female students are more likely to opt out of a second higher-level physics course. Thus, the broad goal of this work is to better understand how to have the most lasting positive impact on female students’ attitudes and motivations towards learning physics after a single physics course in high school. Through longitudinal case studies of six female students using the frameworks of episodic memory and physics identity, we explore the most impactful features of students’ high school physics experiences. The data is drawn from three years of student interviews and one initial student survey. Our results indicate that the students could remember in detail and with longevity their experiences with physics causing high arousal and negative initial valence, such as teachers presenting physics knowledge in a counter-intuitive way. The students can remember the context but not the details of their experiences with physics causing low arousal and non-neutral valence, such as their teacher sharing a story about physics. Experiences that were eventually tied to positive valence had positive impacts on female students’ physics identity maintenance, such as problem solving activities where no one was left behind. 相似文献

This article explores how the doing of social class and gender can intersect with the learning of science, through case studies of two male, working-class university students’ constitutions of identities as physics students. In doing so, I challenge the taken-for-granted notion that male physics students have an unproblematic relation to their chosen discipline, and nuance the picture of how working-class students relate to higher education by the explicit focus on one disciplinary culture. Working from the perspective of situated learning theory, the interviews with the two male students were analysed for how they negotiated the practice of the physics student laboratory and their own classed and gendered participation in this practice. By drawing on the heterogeneity of the practice of physics the two students were able to use the practical and technological aspects of physics as a gateway into the discipline. However, this is not to say that their participation in physics was completely frictionless. The students were both engaged in a continuous negotiation of how skills they had learned to value in the background may or may not be compatible with the ones they perceived to be valued in the university physicist community. 相似文献

It is a widely held view that students’ epistemic beliefs influence the way they think and learn in a given context, however, in the science learning context, the relationship between sophisticated epistemic beliefs and success in scientific practice is sometimes ambiguous. Taking this inconsistency as a point of departure, we examined the relationship between students’ scientific epistemic beliefs (SEB), their epistemic practices, and their epistemic cognition in a computer simulation in classical mechanics. Tenth grade students’ manipulations of the simulation, spoken comments, and behavior were screen and video-recorded and subsequently transcribed and coded. In addition, a stimulated recall interview was undertaken to access students’ thinking and reflections on their practice, in order to understand their practice and make inferences about their process of epistemic cognition. The paper reports on the detailed analysis of the data sets for three students of widely different SEB and performance levels. Comparing the SEB, problem solutions and epistemic practices of the three students has enabled us to examine the interplay between SEB, problem-solving strategies (PS), conceptual understanding (CU), and metacognitive reflection (MCR), to see how these operate together to facilitate problem solutions. From the analysis, we can better understand how different students’ epistemic cognition is adaptive to the context. The findings have implications for teaching science and further research into epistemic cognition. 相似文献

In this forum we engage in a dialogue with Allison Gonsalves’s paper ‘“Physics and the girly girl—there is a contradiction somewhere”: Doctoral students’ positioning around discourses of gender and competence in physics’. In her paper Gonsalves uses a sociocultural approach to examine women doctoral students’ stories about becoming physicists. In doing so her paper focuses on how discourses of masculinity and femininity can create available and unavailable positions for the women students. In this dialogue we do a parallel reading of two of the student narratives presented by Gonsalves, using Judith Butler’s (1990) concept of discursive agency as a means to more explicitly bring the affordances for women identity constitution offered by their localized physicist context to the fore, rather focusing on its, often more visible, constraints. 相似文献

The decline in the popularity of physics over the period of secondary schooling and its consequent low uptake at A‐level and beyond continues to cause concern on educational and economic grounds. The aim of this study is to explore whether physics might be made more attractive to students by employing an extended range of classroom and laboratory activities to teach it. Specifically, the study scores the popularity of a range of activities, students’ perceptions about how often these activities are used to teach physics, and whether students consider them educationally useful. Students appear to think in terms of written activities, passive activities, social activities and constructive activities. Written activities are relatively unpopular and seen as educationally less effective, but students perceived them as used frequently. Social activities such as group work are more popular. The most popular activities are constructive activities, such as doing experiments; these are seen as educationally useful, but are perceived as being used less often than other activities. While there are legitimate limitations on the types of activities that can be used, these findings add to our appreciation of which teaching activities students like and value. 相似文献

A stream of debate (including a previous special issue of this journal (25(1) 2014)) has made claims not just for ‘bringing knowledge back in’ as the framing underpinning of the school curriculum, but that subjects associated with disciplinary and disciplined knowledge forms have a particular power and that these characteristics are important to preserve in curriculum frameworks. This paper draws on a major Australian research project studying school and university physics in the context of these arguments to revisit the issue of the ‘discipline’ of physics and the curriculum logics for physics. Given that disciplines are social in origin and changing and expanding over time, can school curriculum be logically derived from the discipline to which they relate? Are questions about student engagement only questions about pedagogy and not curriculum? Does a focus on disciplinary knowledge mean that the role of school in forming identities and values is avoidable as a significant feature of what the curriculum does? The findings from the project are used both to illustrate and test these questions, and to challenge some over-simple assumptions about the verticality of this form of knowledge for education purposes. 相似文献

This paper presents a case study of how the interactive whiteboard (IWB) may facilitate collective meaning-making processes in group work in engineering education. In the case, first-year students attended group-work sessions as an organised part of a basic physics course at a Norwegian university college. Each student group was equipped with an IWB, which the groups used to write down and hand in their solutions to the physics problems. Based on a Vygotskian, dialectical stance, this study investigates how the students used the IWB in the group-work situation. From qualitative analysis of video data, we identified four group-work processes where the IWB played a key role: exploratory, explanatory, clarifying and insertion. The results show that the IWB may facilitate a ‘joint workspace’, a social realm in which the students’ dialogues are situated. 相似文献

The development and validation of a test of biology‐related attitudes (TOBRA) is described. This instrument was developed for science students in grades 10‐12 in Indonesia; however, the procedures for validation of the instrument will be of general interest to science educators. These procedures included the use of latent partition analysis to examine the conceptual structure of TOBRA. 相似文献

The whole theoretical framework of physics rests only on a few but profound principles. Wigner enlightened us by elucidating
that “It is now natural for us to try to derive the laws of nature and to test their validity by means of the laws of invariance,
rather than to derive the laws of invariance from what we believe to be the laws of nature.” Issues pertaining to symmetry,
invariance principles and fundamental laws challenge the most gifted minds today. These topics require a deep and extensive
understanding of both ‘quantum mechanics’ and the ‘theory of relativity’. We attempt in this pedagogical article to present
a heuristic understanding of these fascinating relationships based only on rather elementary considerations in classical and
quantum mechanics. An introduction to some fundamental considerations regarding continuous symmetries, dynamical symmetries
(Part 1), and discrete symmetries (Part 2) (parity, charge conjugation and time-reversal), and their applications in atomic,
nuclear and particle physics, will be presented. 相似文献

Bhabha’s scientific research contributions are descibed in the context of his life and contemporary science. During the Cambridge period (1927–1939), he worked in positron theory (Bhabha scattering), cosmic rays (Bhabha-Heitler theory of cosmic ray showers, prediction of heavier electrons) and meson theory. In Bangalore during 1939–1945, he worked on classical relativistic spinning particles (Bhabha-Corben equations), meson theory and initiated experimental work in cosmic rays in India. He then founded Tata Institute of Fundamental Research in 1945 at Bombay and moved there. Here he started work on relativistic wave equations (Bhabha equations.). He also initiated India’s nuclear energy programme in 1948 and this was his main preoccupation later. 相似文献

This article is the second part of our review of the important role that symmetry plays in atomic and subatomic physics. We
will concentrate on the discrete symmetries — parity, charge conjugation, and time reversal — that have played a significant
part in the development of the ‘standard model’ of particle physics during the latter part of the 20th century. The importance
of experimental tests of these symmetries, in both atomic and particle physics, and their sensitivity to new phenomena is
also discussed. To conclude, we describe how ‘symmetry breaking’ in the standard model leads to the generation of mass via
the Higgs mechanism and how the search for evidence of this symmetry violation is one of the principal goals of the Large
Hadron Collider, which began operating at CERN, Switzerland in 2009. 相似文献

With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers’ cultural and economic assets, or capital, according to the work of Pierre Bourdieu’s sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers’ positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups’ habituses are described and analyzed; (1) The Manager of the Traditional, (2) The Challenger for Technology and (3) The Challenger for Citizenship. By constructing the habitus of the teachers in the different groups we can explain why teachers teach as they do and thereby make a contribution to both science education research and to teaching training, whereas reflective approach which also includes the individual dispositions and representations are paramount. In our paper we elaborate the grounds and implications of these findings further. 相似文献

Laboratory experiments develop students’ skills in dealing with laboratory instruments and physical processes with the objective of reinforcing the understanding of the investigated subject. In nuclear engineering, where research reactors play a vital role in the practical education of students, the high cost and long construction time of research reactors limit their accessibility to few educational programmes around the world. The concept of the Internet Reactor Laboratory (IRL) was introduced earlier as a new approach that utilises distance education in nuclear reactor physics laboratory education. This paper presents an initial assessment of the implementation of the IRL between the PULSTAR research reactor at North Carolina State University in the USA and the Department of Nuclear Engineering at Jordan University of Science and Technology (JUST) in Jordan. The IRL was implemented in teaching the Nuclear Reactor laboratory course for two semesters. Feedback from surveyed students verifies that the outcomes attained from using IRL in experimentation are comparable to that attainable from other on-campus laboratories performed by the students. 相似文献
