In Part I, the nature of scalars and vectors was discussed for the Newtonian world. However, in the relativistic world, physical quantities follow Lorentz transformations. This change of transformation from Galilean to Lorentz results in interesting distinctions in their properties: mass and time are no longer scalars, time and space become intertwined, etc. This part discusses the nature of scalars and vectors in the relativistic world.  相似文献

The present paper presents a historical study on the acceptance of Newton??s corpuscular theory of light in the early eighteenth century. Isaac Newton first published his famous book Opticks in 1704. After its publication, it became quite popular and was an almost mandatory presence in cultural life of Enlightenment societies. However, Newton??s optics did not become popular only via his own words and hands, but also via public lectures and short books with scientific contents devoted to general public (including women) that emerged in the period as a sort of entertainment business. Lectures and writers stressed the inductivist approach to the study of nature and presented Newton??s ideas about optics as they were consensual among natural philosophers in the period. The historical case study presented in this paper illustrates relevant aspects of nature of science, which can be explored by students of physics on undergraduate level or in physics teacher training programs.  相似文献

In Victoria, students intending to become physics teachers must choose to study physics in the final two years of high school, and then for at least two years at tertiary level. For those who have not taken this route there has been little access to the study of physics at a tertiary level and to a career in physics teaching. The Graduate Diploma in Physics and Education at La Trobe University offers graduates who have not studied physics as part of their undergraduate degree an opportunity to train as physics teachers. Implementation of the diploma has entailed a re-examination of the content and teaching style of undergraduate physics. In this paper, the course structure as a whole will be outlined and the physics taught as part of the diploma described. The preliminary results of the on-going course evaluation will be presented.

This study explored the process of physics teaching assistants’ (TAs) PCK development in the context of teaching a new undergraduate introductory physics course. Matter and Interactions (M&I) has recently adopted a new introductory physics course that focuses on the application of a small number of fundamental physical principles to the atomic and molecular nature of matter. The purpose of this study is to describe how the PCK of physics TAs in the M&I course was developed and enacted. Data collection began during the TA preparation workshop that was held before the semester and continued during the recitation and laboratory classes that the TAs taught during the semester. Through a qualitative, multiple case study research design, data were collected from multiple sources: non-participant observations, digitally recorded video, semi-structured interviews, TAs’ written reflections, and researchers’ field notes. Data analysis consisted of cross-case and within-case analyses. Data were analyzed using a constant comparative method. After data analysis, 2 main themes emerged related to the development of TA’s PCK: (a) TAs’ PCK developed from propositional knowledge to personal practical knowledge and (b) the process of knowledge development consisted of 3 phases: accepting, actualizing, and internalizing. The results of this study will not only contribute to the quest to identify the nature of professional knowledge of science teaching but also help guide preparation for innovative introductory physics courses and other college level science courses in the future.  相似文献

Experimental physics is seen as an essential part of tertiary physics education. Students are supposed to develop practical skills and advance from closed ‘cookbook’ experiments to open experiment and design experiment procedures independently. As a consequence tertiary practical physics courses increase in the level of challenge throughout an undergraduate degree program. The research reported here consists of an investigation of two solely laboratory-based experimental physics courses: a second-year course Experimental Physics and Instrumentation, and a third-year course Advanced Experimental Physics, offered at a New Zealand tertiary institution. The research suggests that although the structure, content, and teaching methods in the two courses vary; there is little difference in students' learning strategies employed in the two courses. It appears bridging experiments may be necessary to help students shift from a highly directive pedagogy at the lower levels of the undergraduate practical physics program, to a more open inquiry approach.

This is an ethnographic study of the trajectories and itineraries of undergraduate physics students at a Mexican university. In this work learning is understood as being able to move oneself and, other things (cultural tools), through the space–time networks of a discipline (Nespor in Knowledge in motion: space, time and curriculum in undergraduate physics and management. Routledge Farmer, London, 1994). The potential of this socio-cultural perspective allows an analysis of how students are connected through extended spaces and times with an international core discipline as well as with cultural features related to local networks of power and construction. Through an example, I show that, from an actor-network-theory (Latour in Science in action. Harvard University Press, Cambridge, 1987), that in order to understand the complexities of undergraduate physics processes of learning you have to break classroom walls and take into account students’ movements through complex spatial and temporal traces of the discipline of physics. Mexican professors do not give classes following one textbook but in a moment-to-moment open dynamism tending to include undergraduate students as actors in classroom events extending the teaching space–time of the classroom to the disciplinary research work of physics. I also find that Mexican undergraduate students show initiative and display some autonomy and power in the construction of their itineraries as they are encouraged to examine a variety of sources including contemporary research articles, unsolved physics problems, and even to participate in several physicists’ spaces, as for example being speakers at the national congresses of physics. Their itineraries also open up new spaces of cultural and social practices, creating more extensive networks beyond those associated with a discipline. Some economic, historical and cultural contextual features of this school of sciences are analyzed in order to help understanding the particular way students are encouraged to develop their autonomy.  相似文献

This article investigates the influence of English as the examination language on the solution of physics and science problems by non-native speakers in tertiary engineering education. For that purpose, a statistically significant total number of 96 students in four year groups from freshman to senior level participated in a testing experiment in the Degree Programme of Aviation at the FH JOANNEUM University of Applied Sciences, Graz, Austria. Half of each test group were given a set of 12 physics problems described in German, the other half received the same set of problems described in English. It was the goal to test linguistic reading comprehension necessary for scientific problem solving instead of physics knowledge as such. The results imply that written undergraduate English-medium engineering tests and examinations may not require additional examination time or language-specific aids for students who have reached university-entrance proficiency in English as a foreign language.  相似文献

In this paper we develop knowledge of the discourse that takes place between teacher and students in two large undergraduate classes which use a flipped, active learning approach. In flipped classes students encounter the content through pre-class resources, freeing up class time for more active engagement with the material. This results in increased opportunities for teacher-student interactions which may be beneficial for learning. Our aim here is to explore the nature and purposes of these dialogues. Two case studies from introductory physics classes at the University of Edinburgh are analysed through a sociocultural perspective. Three main purposes of dialogues are observed: (1) Involving students in sense-making, (2) Guided expert modelling and (3) Wonderment questions. We found that the dialogues predominantly use a triadic Initiation, Response, Feedback (IRF) format and are authoritative in nature, but work together to create an interactive learning environment that can be described as ‘ideologically dialogic’  相似文献

在讨论分子的能级等问题时,由于要求得分子体系的定态薛定谔方程的严格解很困难,因此,不得不求助于各种近似的方法。然而,通常我们采用的近似方法,仍存在着较繁的数学运算过程。本文尝试应用数值估算这样一种近似方法,估算双原子分子的能级差。既可避免较繁的定量计算,又说明了与分子光谱事实相符的若干基本问题。  相似文献

This study examines the epistemic beliefs about justification employed by physics undergraduate and graduate students and faculty in the context of solving a standard classical physics problem and a frontier physics problem. Data were collected by a think-aloud problem solving session followed by a semi-structured interview conducted with 50 participants, 10 participants at freshmen, seniors, masters, PhD, and faculty levels. Seven modes of justification were identified and used for exploring the relationships between each justification mode and problem context, and expertise level. The data showed that justification modes were not mutually exclusive and many respondents combined different modes in their responses in both problem contexts. Success on solving the standard classical physics problem was not related to any of the justification modes and was independent of expertise level. The strength of the association across the problem contexts for the authoritative, rational, and empirical justification modes fell in the medium range and for the modeling justification mode fell in the large range of practical significance. Expertise level was not related with the empirical and religious justification modes. The strength of the association between the expertise level and the authoritative, rational, experiential, and relativistic justification modes fell in the medium range, and the modeling justification mode fell in the large range of practical significance. The results provide support for the importance of context for the epistemic beliefs about justification and are discussed in terms of the implications for teaching and learning science.  相似文献
