Describes a study investigating the effects of short-term interventions on preservice elementary teachers' understanding of the topic of ozone depletion and whether complex issues can be dealt with successfully through short-term intervention. Reports that preservice teachers' understanding improved through a short-term intervention using a mix of…

Children's ideas about radiation and radioactivity are reviewed and several common areas of misunderstanding are identified. An approach to teaching the topic at the secondary school level which seeks to specifically address known difficulties is outlined. (CW)

Examines the technical vocabulary of genetics as a source of error and confusion. Suggests that it is necessary to identify different types of problems associated with terminology and to organize them into logical classes to deal effectively with the difficulties. Highlights terms misused in textbooks. (RT)

Investigated was the influence of an instructional strategy to help freshmen undergraduate students overcome misconceptions regarding the nature of evolutionary theory. Discusses the strategy that included writing statements, small group discussion, teacher presentation, interactive lecture/discussion, and individual reflections. (YP)

Investigated was the nature of teachers' ideas about force and gravity, changes in materials, and energy. Information was obtained by using interview-about-events and interview-about-instances techniques. Examples of teachers' conceptions and ways of thinking are included. (YP)

Considers what college students think reasoning about physics involves. Discusses whether it is possible to identify students' general conceptions of physics and the effects of a course on students' concepts. Data indicated that students' understandings had an effect on problem solving, qualitative problems, and misconceptions. (YP)

Proposes elements of a model of knowledge structures used in comprehending and generating graphs. Uses the competence model to attempt to organize and interpret findings on misconceptions in graphing. Discusses two types of common misconceptions; treating the graph as a picture and slope-height confusions. (YP)

The misconceptions related to the concepts of force and acceleration among college students are explored. Misconceptions are identified and their occurrence among a large percentage of students are observed. Provided are some implications for physics teaching and an eight-item test. (Author/YP)

When interviewed, 105 third-grade students indicated that they did not view retardation as a set of behaviors, but as a trait, defined abstractly and perceived to be both predetermined and largely irreversible through personal effort.
