Experts' Views on Using History and Philosophy of Science in the Practice of Physics Instruction

This study examines the views of a representative sample of experts in physics, physics education and history and philosophy of science (HPS) on the incorporation of HPS based materials in physics instruction. The obtained spectrum of views addresses three areas: the rationale to include HPS, the most appropriate ways of doing so, and anticipated difficulties in such a new educational approach. The elicited views, interpreted and categorized, reflect the attitude of the community of science educators in Israeli colleges and universities with regard to the subject. The constructed profiles indicate low awareness of the recent changes in the understanding of learning and the role of HPS in the light of these changes. Such knowledge can guide the activities of those who devote their efforts to constructing and implementing learning materials utilizing HPS contents in science education.     

Are Virtual Labs as Effective as Hands-on Labs for Undergraduate Physics? A Comparative Study at Two Major Universities

Most physics professors would agree that the lab experiences students have in introductory physics are central to the learning of the concepts in the course. It is also true that these physics labs require time and money for upkeep, not to mention the hours spent setting up and taking down labs. Virtual physics lab experiences can provide an alternative or supplement to these traditional hands-on labs. However, physics professors may be very hesitant to give up the hands-on labs, which have been such a central part of their courses, for a more cost and time-saving virtual alternative. Thus, it is important to investigate how the learning from these virtual experiences compares to that acquired through a hands-on experience. This study evaluated a comprehensive set of virtual labs for introductory level college physics courses and compared them to a hands-on physics lab experience. Each of the virtual labs contains everything a student needs to conduct a physics laboratory experiment, including: objectives, background theory, 3D simulation, brief video, data collection tools, pre- and postlab questions, and postlab quiz. This research was conducted with 224 students from two large universities and investigated the learning that occurred with students using the virtual labs either in a lab setting or as a supplement to hands-on labs versus a control group of students using the traditional hands-on labs only. Findings from both university settings showed the virtual labs to be as effective as the traditional hands-on physics labs.     

Whatever happened to STS? Pre-service physics teachers and the history of quantum mechanics

If issues in the history and philosophy of science and those related to science, technology and society are generally accepted in policy, how ought these be handled in practice? Mandate in policy does not guarantee implementation in practice. Indeed, HPS and STS have for decades been marginalized in the curriculum. Subject areas designated to teach components of HPS and STS, such as design and technology, social studies and science, seem preoccupied with other aspects of the curriculum and rarely get around to HPS and STS. This study aimed at eliciting pre-service physics teachers’ perspectives on using HPS to address quantum mechanics and scientific literacy. Through questionnaires, observation of and participation in a physics methods class, 16 pre-service teachers were asked to identify topics they considered problematic to teach or learn. They were challenged to identify those topics that could effectively be taught or learned from HPS. The pre-service teachers agreed that HPS and STS were more appealing for teaching some topics, such as quantum mechanics, which is the focus of this article. This intervention in physics teacher education demonstrates the importance of using specific methods in physics instruction to demonstrate the value of HPS in scientific literacy.     

Why Implementing History and Philosophy in School Science Education is a Challenge: An Analysis of Obstacles

Teaching and learning with history and philosophy of science (HPS) has been, and continues to be, supported by science educators. While science education standards documents in many countries also stress the importance of teaching and learning with HPS, the approach still suffers from ineffective implementation in school science teaching. In order to better understand this problem, an analysis of the obstacles of implementing HPS into classrooms was undertaken. The obstacles taken into account were structured in four groups: 1. culture of teaching physics, 2. teachers?? skills, epistemological and didactical attitudes and beliefs, 3. institutional framework of science teaching, and 4. textbooks as fundamental didactical support. Implications for more effective implementation of HPS are presented, taking the social nature of educational systems into account.     

Professors' and students' conceptualizations of the learning task in introductory physics courses

What are students expected to learn in physics courses? Eight expert physics teachers and researchers, two from the University of Western Ontario in Canada, Cambridge University in the United Kingdom, Stanford University in the United States of America, and Monash University in Australia, described their perceptions of learning in their courses. Students from the courses were then interviewed for their perceptions of learning in physics courses. In their courses, professors focused on the development of intellectual skills, assuming that students had a specific physics vocabulary. Students, however, were aware of their own limitations and suggested that professors should take nothing for granted. Students considered that to be a good teacher, a professor should know the perspective of the students and should start at the students' level. The results suggested that the intellectual challenge of learning physics merits early explanation.

Comparing Teaching Approaches About Maxwell’s Displacement Current

Due to its fundamental role for the consolidation of Maxwell’s equations, the displacement current is one of the most important topics of any introductory course on electromagnetism. Moreover, this episode is widely used by historians and philosophers of science as a case study to investigate several issues (e.g. the theory–experiment relationship). Despite the consensus among physics educators concerning the relevance of the topic, there are many possible ways to interpret and justify the need for the displacement current term. With the goal of understanding the didactical transposition of this topic more deeply, we investigate three of its domains: (1) The historical development of Maxwell’s reasoning; (2) Different approaches to justify the term insertion in physics textbooks; and (3) Four lectures devoted to introduce the topic in undergraduate level given by four different professors. By reflecting on the differences between these three domains, significant evidence for the knowledge transformation caused by the didactization of this episode is provided. The main purpose of this comparative analysis is to assist physics educators in developing an epistemological surveillance regarding the teaching and learning of the displacement current.     

Success of students in a college physics course with and without experiencing a high school course

High school students with high ability were enrolled in a standard college physics course for each of two summers with the same professor, same course outline, same textbook, same laboratories, and the same examinations. Half of each group had completed a high school physics course; half had not. Dormitory counselors were available for assistance and support. In addition, tutors were available in the laboratories to provide any help necessary with interpretation of lectures and performances in the laboratory, and with mathematical computation. Pre- and posttest measures concerning course content and attitude were given. After the eight-week summer instruction, the students who had not completed high school physics performed as well on the final course examination; there were no differences with respect to course grade or attitude toward physics. The group that had not completed high school physics used the tutors provided far more frequently than did students who had completed the high school course. When high-ability students are enrolled in college physics with tutors made available for needed assistance, there appears to be no advantage for students to complete the standard high school physics course.     

An Exploratory Study of Student Perceptions of Which Classroom Policies Are Fairest

Fairness is a critical issue in the educational setting, and the research is unified in the view that professors need to be fair in setting course policies and procedures. However, many unanswered questions still remain as to which specific classroom policies and procedures students find fair or unfair. This study explores student perceptions of which course policies provide the fairest treatment for all students in a college class. In addition, we also investigate the presence of a relationship between students' locus of control and their perceptions of the fairest course policies. Data were provided by 254 undergraduate students enrolled in sections of an introductory operations management course or an introductory management information systems course. As an initial, exploratory study in this specific area, eight common classroom policy situations were investigated. Although, not surprisingly, all students did not agree on which policy was the fairest for any given classroom situation, we were able to identify those policies considered fairest by the most students. The results can help professors develop course policies that improve students' perceptions of fairness in the college classroom.     

The effects of perceived professor competence,warmth and gender on students’ likelihood to register for a course

Abstract

The present research examined whether students’ likelihood to take a course with a male or female professor was affected by different expectations of professors based on gender stereotypes. In an experimental vignette study, 503 undergraduate students from a Canadian university were randomly assigned to read a fictitious online review, similar to those found on RateMyProfessors.com, that varied professor gender, overall quality score and level of caring for students. Students responded to items assessing their likelihood to take a course with the professor, perceived competence and warmth of the professor, and their own gender bias. An analysis of variance revealed an interaction between professor gender, student gender, quality score and caring. When quality score was low, male students indicated a lower likelihood of taking a course with female professors who were not described as caring. Regression analyses showed, however, that students' gender bias was negatively associated with likelihood to take a course with a female professor. These results imply that student gender plays a role in evaluations of female professors who do not display stereotypical warmth but that gender bias, which is typically higher for males at the group-level, may be an underlying factor.     

Girls,boys and conceptual physics: An evaluation of a senior secondary physics course

This paper reports an evaluation of the physics course at Dickson College (ACT) looking at students' high school experience, their expectations before beginning and their impressions and feelings during the course. In general, students seem to have a fairly negative approach to physics, enrolling for a variety of often vague utilitarian reasons but with little expectation of enjoyment or interest. These opinions were most prevalent in girls who tend to find the content difficult and the course as a whole uninteresting. There is also a significant difference between girls and boys in their response to different types of assessment items. In an attempt to enhance the level of interest and enjoyment in students we have been phasing in a more ‘conceptual’ approach to the teaching of physics.

Using Biomedically Relevant Multimedia Content in an Introductory Physics Course for Life Science and Pre-health Students

We will describe a one-quarter pilot algebra-based introductory physics course for pre-health and life science majors. The course features videos with biomedical experts and cogent biomedically inspired physics content. The materials were used in a flipped classroom as well as an all-online environment where students interacted with multimedia materials online and prior to engaging in classroom activities. Pre-lecture questions on both the medical content covered in the video media and the physics concepts in the written material were designed to engage students and probe their understanding of physics. The course featured group discussion and peer-lead instruction. Following in-class instruction, students engaged with homework assignments which explore the connections of physics and the medical field in a quantitative manner. Course surveys showed a positive response by the vast majority of students. Students largely indicated that the course helped them to make a connection between physics and the biomedical field. The biomedical focus and different course format were seen as an improvement to previous traditional physics instruction.     

Four approaches to preservice teachers’ involvement in the writing of case stories: a qualitative research project

In this paper, professors’ framings for student-written cases in six elementary teacher education classes are examined. Analysis procedures were qualitative. There were similarities and differences in course syllabi and materials defining case writing, time spent on cases in class, ways of modeling cases, comments to students on drafts, and professors’ reasons for selecting favorite cases. All professors felt that a good case reflected a genuine dilemma which contained details, support, and reflection. Findings showed that writing roles within the research project had an impact upon ways in which case writing was directed, and how the professors thought about cases and reflected upon the experience afterward. Through their experiences with case writing and through engaging in self-inquiry about case writing, the professors came to understand their students in different ways, students came to understand professors and teaching in different ways, and professors developed new insights into their own practices.     

Faculty and online education as a mechanism of power

This study uses a critical perspective to examine how online education is used in brick-and-mortar institutions as a mechanism through which power is exercised by and against professors who teach online. Based on a larger study of 25 professors and administrators at four institutions, this work focuses on the experiences of 12 professors. Foucault’s conceptualization of power framed our interpretation of interviews conducted with these professors. Our findings suggest online education enhanced faculty autonomy and visibility, but that it was also used to control faculty members, and for some professors, it was used to alter their professional identities.     

Integrator element as a promoter of active learning in engineering teaching

In this paper, we present a teaching proposal used in an Introductory Physics course to civil engineering students from Porto's Engineering Institute/Instituto Superior de Engenharia do Porto (ISEP). The proposal was born from the need to change students’ perception and motivation for learning physics. It consists in the use of an integrator element, called the physics elevator project. This integrator element allows us to use, in a single project, all the content taught in the course and uses several active learning strategies. In this paper, we analyse this project as: (i) a clarifying element of the contents covered in the course; (ii) a promoter element of motivation and active participation in class and finally and (iii) a link between the contents covered in the course and the ‘real world’. The data were collected by a questionnaire and interviews to students. From the data collected, it seems that the integrator element improves students’ motivation towards physics and develops several skills that they consider to be important to their professional future. It also acts as a clarifying element and makes the connection between the physics that is taught and the ‘real world’.     

Educational reconstruction of physics content to be taught and of pre-service teacher training: a case study

This paper reports an explorative study in which innovations in a piece of physics curriculum for high school level have been converted into innovations in methods and contents for physics teacher education. The case study concerns the teaching of physics modelling in a pre-service teacher training course. The structure and content of the course have been both organized in order to prepare teachers to carry out the teaching tasks required from the proposed teaching/learning approach. This approach involves substantial modifications in learning sequences as well as in the teacher's role and in teaching methods. The course intends to give to prospective teachers experience of the same learning environments as they are supposed to realize in their future classrooms and to make them reflect upon the dynamics of their experiences in order to generate metalearning development. The qualitative results that have been collected suggest that metareflection helps prospective teachers to generate significant changes in their teaching/learning approach.

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.     

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.
