Examined are first-year medical students' (n=160) explanations of complex concepts in cardiopulmonary physiology following a lecture series. The results revealed systematic misconceptions by the students in developing a pathophysiological model of the problem. The implications for science instruction within a medical curriculum are discussed.…

Examines the development of students' understandings about fractions during six weeks of instruction. Reports that all students possessed informal knowledge disconnected from their knowledge of fraction symbols and procedures and that knowledge of rote procedures often interfered with students' attempts to build on their informal knowledge.…

During the last 10 years, cognitive science researchers have produced research findings that have great potential for increasing students' understanding of science. However, commercial publishers continue to produce textbooks and teacher's guides in traditional ways. This project developed a prototype unit which used an alternative approach to…

This paper reports an action study of conceptual change in mechanics using an instructional strategy based on a constructivist view of learning. The aims of the study were to determine: (1) what effect the instructional strategy had on achieving conceptual change; (2) what devices or strategies students used in their attempts to understand…

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)

This study compared the effects of cooperative learning groups to traditional instruction in remediating students' misconceptions about temperature. Students from grades 3, 4, and 5 in two rural elementary schools participated in the study. Students completed a pretest, a cognitive conflict laboratory activity and a posttest that measured…

Three purposes of this study were to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for high school physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this…

This paper aims to clarify and describe the process of change in learners' conceptual understanding of natural phenomena. It begins by reviewing the existing literature on models of conceptual change and on children's conceptions in a number of selected topic areas. Strategies for exploring and developing children's ideas in these areas have also…

Focuses on the conceptual change processes of 17 fourth-grade students as they grapple with the abstract concept of human rights. Discusses limitations and successes in students' learning within the framework of conceptual change and motivation research. (CFR)
