One issue of interest to practitioners and researchers in science centres concerns what meanings visitors are making from their interactions with exhibits and how they make sense of these experiences. The research reported in this study is an exploratory attempt, therefore, to investigate this process by using video clips and still photographs of…

A model for problem solving stressing both psychological and cultural influences is presented. This model is based on the analyses of how graduate students (n=10) solve organic synthesis problems, along with two models of problem solving and a constructivist epistemological stance. (KR)

Using a paper-and-pencil test consisting of multiple-choice situational questions which also require reasoning for the choices made, common misconceptions in light were identified. It was found that most of the students understand the basic properties of light at a knowledge level but had difficulty applying these concepts in novel situations.…

Described is the work done with preservice science teachers in a course that aims to increase students' abilities to reflect on their own pedagogical understandings. A description of the context of the course, a clarification of the notion of reflection, and a discussion of interviewing activities are included. (30 references) (KR)

The consistency, if any, with which force concepts are used by individual students in different, but closely related, contexts was investigated. A total of 534 university and high school students were tested to elicit their beliefs about the forces acting on various objects. Students' beliefs about the forces acting on objects at rest and in…

An investigation of students understandings of acids and bases using concept maps, multiple-choice tests, and clinical interviews is described. The methodology and resulting analysis are illustrated with two abbreviated case studies selected from the study. Discussion of concept mapping points to how it starkly represents gaps in the understanding…

Discusses the rationality of students' alternative frameworks by considering the role played by their beliefs, their understanding of other views, and the reasons for justification or rejection. Investigates the way in which 14-year-old boys see the effects of classroom learning experience on their ideas. (Author/YP)

Investigates the relevance and concomitant impact of sociocultural experiences upon the scientific literacy of 87 students, aged 13 to 16, concerning their comprehension and assimilation of scientific data involving solar eclipses. Results indicate that the students' nonscientific conceptions about solar eclipses, generated through sociocultural…
