We use the framework of cognitive resources to investigate how students construct understanding of a complex physics topic, namely, a photovoltaic cell. By observing students as they learn about how a solar cell functions, we identified over 60 distinct resources that learners may activate while thinking about photovoltaic cells. We classify these…

Video recordings of Year 11 physics lessons were analyzed to identify key features of teacher explanations. Important features of the explanations used included teachers' ability to move between qualitative and quantitative modes of discussion, attention to what students require to succeed in high stakes examinations, thoughtful use of…

The article is addressing how students reason about the origin and development of the universe. Students' own views as well as their descriptions of physical models are analysed. Data consists of written surveys, and interviews of a subset of the students. Most of the students relate to the Big Bang model when describing the origin of the…

Probes, through interviews with members of the setting panel, the process of setting the first external test for the Victorian Certificate of Education (VCE) physics course when it was implemented in 1992. Some implications are noted for future efforts to reform curriculum and assessment in physics, and for current classroom practice. (Author/MM)

Describes a laboratory-based program in physics designed to help students build effective links between the mathematical equations used to solve problems in mechanics and the real world of moving objects. Conducts the study among senior college students and points out the value of laboratory work in science education for development of thinking…

The results are described of two case studies on the conceptions and classroom practice of two Portuguese physics and chemistry teachers on the role of problem solving in the teaching/learning of science. One of these teachers was a novice and the other had about 20 years of teaching experience. The data were obtained from a questionnaire, a…

The issue of unfairness arises in high-stakes public examinations when students choose questions from alternatives that are offered and marks on the alternatives turn out to be discrepant. This paper addresses and defines unfairness and discrepancy in the context of alternative questions in Physics Tertiary Entrance Examinations (TEE) in Western…

This paper reports and discusses the principal findings of an Australian study exploring the decisions of high achieving Year 10 students about taking physics and chemistry courses (Lyons, 2003). The study used a "multiple worlds" framework to explore the diverse background characteristics that previous quantitative research had shown…
