Teachers of 9 and 10 year olds were found to use varied versions of lessons that increase conceptual understanding. Their effectiveness in supporting conceptual understanding was compared experimentally. Findings and implications for science teaching are discussed. (Author/DKM)

This conceptual framework is grounded in the data analysis of transcribed interviews with 50 Ontario teachers and the text of a 7-month online discussion group among 25 principals from England, Ireland, Canada, United States, Australia, and New Zealand. Both methods were employed with the stated purpose of understanding emotional experiences of…

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)

The substantial interest exhibited in the last decade in the identification of students' misconceptions of a wide range of scientific concepts has not extended to identification of students' misconceptions of the nature of science itself. This study examined the attitudes of 32 secondary school students, each from Canada, the United States, and…

This paper addresses the evidence that secondary school students use to imply that they understand something in mathematics. As part of a larger study, an open-ended questionnaire probing several aspects of metacognitive self-knowledge, was administered to students (N=72) in four schools. Two previously identified types of understanding were…

This paper describes the actions of one secondary school mathematics teacher in establishing a community of mathematical practice within which students acquire not only knowledge and skills, but also the epistemological values of mathematics. Classroom observations over a period of 18 months, together with interview and questionnaire data, are…

Reports on the results of a study done in Australia in which students in grades 5, 7, 9, and 11 were given word association tests and were asked to react to photographs in an effort to determine their environmental knowledge and attitudes. Lists the key words used as the stimuli. (TW)

Videotaped interviews of 29 Australian students from grades 1-3 were analyzed to assess and compare the processing loads of mathematical representations and strategies used by teachers and children to learn the concept of place value. Results indicated that some representations and strategies impose an unnecessary processing load that can…
