This paper is the third report on the changes in attitudes and interests of Danish upper secondary school students. It describes changes in student interests and attitudes and the main problems encountered in causing change. Recommendations to science educators are included. (YP)

Investigated was the intellectual behavior of 66 student teachers of science. Suggests that the degree of integration of teaching practice with theoretical studies may be a more important factor than length of teaching practice. (YP)

Investigated were 17-year-old British students' comments on their previous science education. Satisfying science education entails (1) relevance, coherence and continuity; (2) concern for student needs; (3) and practical work such as inquiry activity. (YP)

Describes a diagnostic evaluation to measure the idea of the living cell as the basic unit of life. Describes the classification of student knowledge as common knowledge, wide-spread lack of knowledge, inadequate alternatives, and contradictions. (YP)

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

Synthesized are the results of five qualitative investigations of high school science classrooms in Western Australia and in the state of Georgia. Gender differences were observed in each study and teachers were not aware of their occurrence. (Author/YP)

Examines whether young children hold naive conceptions of speed and whether the nature of their concepts could be a causal factor in pedestrian accidents. Finds that children hold a range of beliefs regarding the concept of speed that would place them at risk. (Author/YP)

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)

Reported are observational limits of detectability for several single stimulus and multi-stimuli observation tasks in secondary level chemistry. Provided are tables of actual results obtained including type of observation, chemical system used, method of determining stimulus magnitude, and observational thresholds. (Author/YP)

Describes an application of methodology based on the Information Integration Theory to study intuitive mastery by 13-14 year-olds of Archimedes' Effect in physics. (Author/YP)

Describes a study of the understanding of basic electrical concepts shown by 15-17 year-old students in England, France, Netherlands, Sweden, and West Germany. Reports substantially the same pattern of learning difficulties across countries. Provides sample items. (Author/YP)

Investigates student engagement patterns in high school science classes. Finds that three to five students, known as target students, monopolized classroom interactions in most classes and they tended to be high-achieving students. Most target students were male and tended to be persistent. Provides a student involvement questionnaire in the…

Examined the evolution of the knowledge and the notions of students in order to see how after one year of university study their concepts and ideas of scientific theory in chemistry had progressed. Reports that sometimes the students' conceptions are modified in the wrong way. (Author/YP)

Examined whether and how the quality of students' explanations of chemical phenomena was affected by changing the method of giving the question and answer between the spoken and written formats. Concluded that there was no difference between the performance of students using any of these combinations of formats. (Author/YP)

Examines the usefulness and limitations of the notion of cognitive structure in science and the idea of mapping or charting it. Surveys several techniques for enumerating cognitive structure and explores possible classroom applications. (GS)
