Teaching and learning about complex scientific content, such as biological evolution, is challenging in part because students have a difficult time seeing the relevance of evolution in their everyday lives. The purpose of this study was to explore the effectiveness of the Teaching for Transformative Experiences in Science (TTES) model (Pugh, 2002)…

This study examines students' understanding of the normative connections between key concepts of cell division, including both mitosis and meiosis, and underlying biological principles that are critical for an in-depth understanding of genetic inheritance. Using a structural equation modeling method, we examine middle school students'…

Reviews and analyzes research related to the teaching and learning of science completed in 1985. Includes: (1) reviews of research; (2) evaluation; (3) student characteristics; (4) attitudes toward science; (5) conceptual reasoning; (6) instructional treatments; (7) cognitive skills; (8) laboratory work; (9) microcomputer applications; (10)…

Argues that, by not considering examples drawn from students' everyday lives, a teacher is detracting from science itself. A challenge is made to Conceptual Change Learning Model advocates and users to embrace the idea of conceptual fitting based upon context as well as conceptual change when considering how students learn. (ZWH)

Summarizes the results of three related studies whose overall purpose was to determine elementary students' conceptions about earthquakes at two widely separated locations in the United States. Certain topics, such as the cause of earthquakes, seemed to cause difficulty for students. New definitional responses emerged in the studies that took…

Examines the research literature in science education to determine how appropriate it is for teaching science to young children 3-5 years of age. In the context of this discussion, a model for the teaching of science in early childhood is presented. For clarity and continuity, the example of teaching electricity is used throughout. (PR)

Evaluates the effectiveness of a course using a constructivist approach in reducing Dutch secondary school students (n=190) misconceptions about force. Concluded that the lessons were effective in changing students' ideas in regard to forces in rest situations and frictional forces and that learning effects were equally distributed over student…

Discusses (1) the need for teachers to understand student conceptions; (2) alternative conceptions that students formulate; (3) changing conceptions; (4) representing conceptual knowledge for studying conceptual change; (5) strategies for inducing change; and (6) a taxonomy of conceptual change. (Contains 61 references.) (MDH)

Presents a summary of teaching practices that are successful in promoting conceptual change based on a study of Grades 4, 8, and 10 and on the research literature. Proposes improvements in teaching methodology. Contains 31 references. (DDR)

Analyzes a teaching episode to determine how a conflict is perceived and overcome by students as a result of verbal interaction between the teacher and the students. Discusses the particulate nature of matter with students aged 15-16 after observing a glass of water containing a rock and an ice cube. (Contains 25 references.) (Author/YDS)

Analyzed operational knowledge of the weight concept of high school students after two educational levels: introductory and advanced physics. Results showed that apparent and true weight concepts are poorly assimilated by most of the advanced placement students. Discusses origins of the shortcomings of the alternative knowledge about weight.…

Measures both teaching efficacy and the holding of specific alternative conceptions of preservice elementary teachers (N=619). Uses a survey to determine the relationship between teaching efficacy and certain alternative conceptions. Contains 77 references. (DDR)
