Girls,boys and conceptual physics: How senior secondary students have responded to a conceptual physics course

This paper presents an evaluation of the Physics course at Dickson College (ACT). It highlights students' expectations before the course, and their impressions and feelings during the course. This is the second evaluation carried out as part of a long term study of student attitudes before and after the introduction of a more ‘conceptual’ approach to the teaching of physics at this college. Overall, this approach has produced a more positive attitude in all students, but more significantly in girls. Specializations: senior physics, chemistry and biology.     

The graduate diploma in physics and education: A teacher training initiative

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. Specializations: Physics education, gender and science teaching. Specializations: Physics education.     

Evaluation of a course designed to teach physics to students of physiotherapy

This paper describes the development and evaluation of a course in physiotherapy whereby the physics fundamental to the modalities of cold, heat and ultrasound therapies was integrated in lectures and actual physiotherapy activities. The design of the course is described together with the perceptions of physiotherapy students regarding the organisation of the course, safety aspects and how well the integration contributed to their understanding of the physics involved in electrotherapy.

Teaching about theories of light in year 12 physics: An historical approach

This paper examines an approach to the teaching of a year 12 Physics topic from within an historical setting. The Victorian Physics course requires teachers to cover each topic within some particular prescribed context, so that the everyday relevance of physics or its interrelationships with other fields of endeavour can be demonstrated. The Light and Matter topic specifies only one context: Landmark Developments. Rather than adopting a ‘names, dates and events’ approach which, for many understandable reasons, most teachers seem to follow, the author has attempted to cover the history in greater detail and more holistically. Specializations: history of physics, nature of science, construction of knowledge, social responsibility in science.     

An intervention study to enhance girls' interest,self‐concept,and achievement in physics classes

Many interest studies have shown the decline of students' interest in physics during secondary education, particularly among girls. Research into physics‐related interests of students suggests applying different measures to reduce or reverse that trend such as: (a) suggesting curricular changes that do justice to the specific interests and experiences of girls, (b) improving the ability of teachers to support girls in the development of a positive physics related self‐concept, and (c) changing to an organizational setting that gives girls a better chance to improve their self‐concept about physics. The purpose of this study was to examine whether these hypothetically effective measures lead to an improvement of the situation for girls when implemented in the physics classroom. The intervention took a whole school year of some 60 one‐hour lessons and comprised 12 experimental and 7 control classes of seventh graders (age about 13). Their immediate and long‐term achievements, as well as their change of interest in physics, their subjectively experienced competence, and their physics‐related self‐concept were assessed by written tests at various stages of the intervention. The intervention proved successful and significantly improved most of these indicators for girls (and boys) in the experimental group. © 2002 Wiley Periodicals, Inc.

A decade of debate on the schooling of girls in physics: Where are we now?

The last decade has seen an explosion of interest in issues concerned with girls and science education, and the nature of the dialogue has become increasingly sophisticated. Current writing stresses the importance of acknowledging differences between women, as well as differences between women and men. This paper will outline some of the positions it is possible to adopt in the discussion. It will raise some questions concerning the implications of the choice of a position for classroom teachers of science and, in particular, physics teachers. Specializations: physics curriculum development, gender and science teaching.     

Gender and physics

Unlike many other countries, physics is highly popular in secondary education in Scotland, with large numbers opting for study at the Higher Grade on which entry to higher education is based. This paper reports a project that explored the attitudes and perceptions of Scottish girls and boys towards physics over the age range of 10-18 years old. Towards the end of primary school, attitudes towards science are very positive and both boys and girls are looking forward to studying more science in secondary school, although there is no evidence that the introduction of primary science has been a factor. By the end of the second year of secondary school, these positive attitudes have declined quite markedly and a significant decline of girls' attitudes towards science relative to boys' attitudes was clearly observed. The success of the Standard Grade physics course (a 2-year course taken in third and fourth year, ages 14-16 approximately) is easy to observe in terms of the restoration of positive attitudes of boys and girls again as the pupils move through third and fourth year. This process is especially clearly marked among girls. Surprisingly, over 90 per cent of the observed fourth year pupils wanted to continue studies in physics but a marked decline in attitude is observed during the Higher Grade course (a 1-year course which follows Standard Grade), this being more marked for boys. If the number of girls in physics is an issue for concern within the structure of Scottish system, then the focus of attention should be the structure and nature of the science course in the early secondary school.     

Project physics in N.S.W.

Conclusions Of all the aspects of classroom environment studied in this research, attention to the social relevance of physics had one of the strongest associations, in a positive sense, with each of the student outcomes. The research showed that positive student outcomes tended to be closely associated with low levels of frustration. Integration of experimental and theoretical aspects of physics tended to be accompanied by positive student outcomes. The integration could well go beyond using experiments merely to illustrate and/or verify principles and theories previously taught. At least in some topics, student understanding of physics could well follow upon and be the outcome of experiences gained during practical work, and some problem-solving by experiments could be given. Despite some inveitable tensions, teachers who favoured student autonomy were generally satisfied with their physics teaching. Moreover, their students reported more growth in personal development areas such as a sense of responsibility than did students who did not experience much autonomy. The multi-media characteristics of Project Physics makes it a particularly suitable approach for including student autonomy. The results indicated that academic achievement is not likely to suffer when attention is given to encouraging student initiative, sense of responsibility, improved study methods and persistence at a task. Such goals are long-term goals and working towards them tends to be accompanied by greater interest in and enjoyment of physics.     

A college of science: Bridging the gap between school and university

Many tertiary institutions in South Africa have implemented schemes to help redress the unfair school educational system. This paper describes one such initiative to increase access and success of educationally disadvantaged students in science. The background of the College of Science and the success of its first intake of students is described with an emphasis on the physics component of the physical sciences course. Sixty six percent of the students passed all three courses in their first year with the most educationally disadvantaged showing the greatest gains.

Perceptions of assessment in a senior physics class

Students' responses to assessment tasks are likely to be affected by a range of factors including teaching approaches, the nature of the curriculum, the nature of the assessment task, socialising influences, and perceptions of the teacher's assessment objectives. This paper describes the perceptions of assessment practices held by senior physics students and their teacher in one Brisbane school. The nature and rationale for these practices were inferred from an examination of school documents. Congruences and dissonances between and within these indicators of physics assessment practices in the school are explored, with particular reference to gender. Specializations: science education, science teacher education, physics education.     

Gender differences in introductory undergraduate physics performance: University physics versus college physics in the USA

Efforts to ameliorate gender disparity in pursuit of science careers in the USA have focused on equalizing girls' participation in pre-college science courses and out-of-school activities. Our examination of nearly 1500 US college students at 16 universities found that gender and preparation both have an impact on success in introductory college physics courses. In terminal, algebra-based physics females perform better than their male classmates. However, in calculus based introductory college physics courses, which are prerequisite to advanced study in many fields, women do significantly worse than their male counterparts with the same background. For both genders, taking a high school course that limits coverage and concentrates more time in in-depth study is associated with better performance in college physics. We conclude that efforts to ensure the success of women entering the physical sciences should concentrate on increasing the depth and reducing the vast coverage of most high school physics courses as well as addressing the apparent bias in college courses that mark the first step in careers within scientific research and engineering.     

Time and space: undergraduate Mexican physics in motion

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.     

Her physics,his physics: Gender issues in Israeli advanced placement physics classes

Gender gaps in physics in favour of boys are more prominent in Israel than in other countries. The main research question is to find out what gender issues are at play in Israeli advanced placement physics classes. Matriculation exam scores from approximately 400 high schools were analysed across 12 years. In addition, semi-constructed interviews were conducted with 50 advanced placement physics students (25 girls and 25 boys). In terms of participation, it was found that the ratio of girls to boys has been unchanged from 1988 to 2000 and is roughly 1:3. In terms of performance, it was found that the final matriculation scores of boys and girls are similar. However, breaking up the final scores into its two components - teachers' given grades and matriculation test scores - showed that boy's test scores are usually higher than girls' test scores, while girls' teachers' given grades are usually higher than boys'. Results from semi-constructed interviews pointed to two factors that are especially unfavourable to many girls: excessive competitiveness and lack of teaching for understanding. Girls' yearning for deep understanding is seen as a form of questing for connected knowledge. It is suggested that instructional methods that foster students' understanding while decreasing competitiveness in physics classes might contribute to girls' participation and performance in advanced physics classes while also supporting the learning of many boys.     

Detection of missing and irrelevant information within paper and pencil physics problems

Secondary 5 students from four schools in Hong Kong were required to classify 18 paper and pencil physics problems in terms of whether the problems contain necessary and sufficient, missing or irrelevant information for their solution. Students' ability to denote missing information correlated rather highly with the solution rates of the problems. In another test, students were asked to classify whether the problems in each of six pairs were similar to or different from each other according to students' self-determined criteria. Students who used a deep structure (i.e. used the underlying physics principles) to classify the problems have significantly higher scores in detecting missing and irrelevant information and in the solution rates than those who used surface structure or features for classification. It is argued that a student who is able to identify what information is sufficient, missing or irrelevant for solving a problem understands the problem structure and so is better able to solve it. Such a student is likely to adopt a deep structure in categorizing physics problems. This latter result corroborates with the findings of the expert-novice research paradigm.

Student views regarding online freshmen physics courses

Background: Nationally, many public universities have started to move into the online course and program market that was previously associated with for-profit institutions of higher education. Public university administrators state that students seek the flexibility of online courses. But do students want to take courses online, especially freshmen-level science courses perceived to be difficult?

Purpose: This study investigated student views related to the potential of a physics course they were currently enrolled in being offered online.

Sample: This study took place at a large, public, mid-western university and involved students enrolled in either the first or second semester of a face-to-face flipped physics course for engineering technology majors.

Design and methods: Discussions with students during the semester about their online course experiences and expectations were used to develop the concourse and subsequently the Q sample to perform a Q methodology study about students’ views regarding taking physics courses online. Additional statements for the concourse and Q sample were taken from communications with administrators at the university. In this way, the statements sorted by the students included those from students and those from administrators. Factor analysis of the Q sorts resulted in three factors, each representing a unique perspective. Interpretations of these perspectives included the analyses of the Q sorts, the researcher’s interactions with students and administrators, and students’ written responses regarding their previous online course experiences and their sorting decisions.

Results: Three unique student views emerged were named: keeping it real and face-to-face, Online could be ok depending upon the course and instructor, and Online not for STEM classes. Consensus among the views is also discussed.

Conclusions: Overall, students’ views are negative concerning having physics courses, including labs, online and those views conflict with statements expressed by administrators regarding students’ desires for online courses at the university.     

Expounding on physics: a phenomenographic study of physicists talking of their physics

Physicists and physics students have been studied with respect to the variation in the ways they expound on their topic of research and a physics problem, respectively. A phenomenographic approach has been employed; six fourth‐year physics students and 10 teacher‐researcher physicists at various stages of their careers have been interviewed. Four qualitatively distinct ways of expounding on physics have been identified, constituting an outcome space where there is a successive shift towards coherent structure and multiple referent domains. The interviewed person is characterized as expressing an ‘object of knowledge’, and the interviewer is characterized as a willing and active listener who is trying to make sense of it, constituting a ‘knowledge object’ out of the ideas expressed and personal experience. Pedagogical situations of analogous character to the interviewer–interviewee discussions are considered in the light of the analysis, focusing on the affordances for learning offered by the different forms of exposition.     

Teaching physics in junior high school: crossing the borders of fear

Israeli junior high‐school science teachers usually have a background in biology, and their knowledge of physics is limited. We show that by improving teachers' qualitative understanding it is possible to increase their confidence and willingness to teach physics. We conducted three‐day workshops for teachers (n = 92), which were followed by ongoing activities and support. The teacher workshops were based on a new qualitative approach that we developed for studying mechanics, which has been shown to be effective with students. A study of teachers who had not participated in the workshop shows that they had the same conceptual difficulties as their students. A comparison of pre‐ and post‐workshop questionnaires indicates that the participating teachers gained self‐confidence in their ability to explain everyday phenomena, changed their views about the relevance and interest of physics to the students and were willing to implement the method in their classes.     

Comprehension of non-technical words in science: The case of students using a ‘foreign’ language as the medium of instruction

This paper reports on an investigation into Hong Kong students' comprehension of English non-technical words used in science. The investigation was conducted in a context in which English, a foreign language to students, is the medium of instruction, in that textbooks and examinations are all in English but the classroom language used is mainly Chinese, with frequent Chinese-English code-switching. A total of 4644 Secondary 4, 5 and 6 students participated in the study. Many students did not correctly comprehend a large proportion of the words, confused them with words that were graphologically or phonetically similar, and even took them for their antonyms. Such poor performance raises doubts as to whether the majority of Hong Kong students have attained a ‘threshold level’ of competence in English to benefit from learning science in English. Specializations: physics education, students' alternative conceptions in science, conceptual change, computer-assisted learning in physics.
