Children's magical explanations and beliefs were investigated in two studies. Found that many four-year olds view magic as a plausible mechanism, yet reserve magical explanations for certain real world events that violate their causal expectations.

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…

The purpose of this study was to identify alternative life and physical science concepts possessed by preservice elementary science teachers (n=49). Science textbooks used in grades 5 and 6 were surveyed and a literature review of alternative life and physical science concepts was conducted. Results of the survey and literature review resulted in…

Perspectives on a psychological approach to learning are offered in this paper. Specific emphasis is directed to the assumption that children possess "minitheories." Minitheories are defined as attempts to make sense of particular kinds of experiences and are explained and delimited by the domain of experience to which they currently apply. This…

Indicates that cognitive style and misconception play a…

Scientific and everyday knowledge domains are compared so as to reveal the distinctive differences between their goals and the cognitive processes used to attain them. The main goals, working goals, learning difficulties, knowledge structure, concept specification, knowledge organization, role of school science, program-solving instruction, formal…

This document examines children's and adults' knowledge of observational astronomy and characterizes the kinds of mental models students form when asked questions in astronomy. Mental models were grouped into three categories: intuitive, synthetic, and scientific. Implications for the design of curricula and for instruction are identified. In…

This document reports the results of a cross-cultural study on children's knowledge about the shape, gravity, movement, and location of the Earth and about the day/night cycle. The subjects of the study were elementary school students from Greece (N=90) and the United States (N=60). The results of the study showed that the children in both samples…

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…
