Reports on a study that addresses the implications of instructional strategies that are used to create cognitive disequilibrations to achieve conceptual change. Discusses several difficulties in the application of such conceptual change strategies. Contains 31 references. (DDR)

Provides a critical analysis of the role that atomic theory plays in the science curriculum from elementary through secondary school. Examines structural concepts from the perspective of the theory of meaningful learning, information processing theory, and the alternative conceptions movement. Contains 54 references. (DDR)

Presents a study that investigated relationships between gender, interest, and experience in electricity. Also explored the effect of conceptual change text manipulations on learning fundamental concepts of direct current. Suggests that conceptual change text manipulations are likely to be effective for both men and women. Contains 57 references.…

Children who come to school without numerical game-playing experience have trouble with math relationships in direct-instruction situations. This article explores the varied roles of active thinking, social interaction, previous knowledge, and child-initiated choice in children's development of math concepts. Self-esteem cannot be built by doing…

Describes an extended investigation of polygons and polyhedra which was conducted in response to a challenge posed in Focus, a newsletter from the Mathematical Association of America (MAA). Students were challenged to construct a polyhedron with faces that measure more than 13 inches to a side. Outlines the process, including the questions posed…

Explains a method to enable students to understand DNA and protein synthesis using model-building and role-playing. Acquaints students with the triplet code and transcription. Includes copies of the charts used in this technique. (DDR)

Identifies and describes the differences in the problem-solving methods used by faculty teaching introductory chemistry and students enrolled in an introductory chemistry course. Results indicate that students correctly solve algorithmic-mode problems more frequently. Contains 33 references. (DDR)

Focuses on the development of graphing skills through a data collection activity that answers the question of the relationship between rubber band width and flight distance. Includes definitions of terms and instructions for helping students construct line and bar graphs. (DDR)

Focuses on the use of push and go toys to discuss with students how the toy acquires potential energy when work is done on it and how this energy is stored in the internal mechanism for later conversion into kinetic energy. (DDR)

Examines the impact of one unit of a curriculum module for sixth grade from the Model-based Analysis and Reasoning in Science (MARS) project. Provides an overview of this unit on mass and discusses three aspects of the evaluation of the unit. Contains 22 references. (DDR)

Provides a comprehensive review of literature regarding misconceptions that are held by secondary students in chemistry. Makes some recommendations based on the research. Contains 77 references. (DDR)

Provides an example that focuses on temperature and illustrates how in-depth study can meet multiple content standards for middle school science and mathematics in the subjects of measurement and data analysis. (DDR)

Proposes a set of questions to help educational planners develop clear, coherent concepts in policy proposals. Guidelines must be used discerningly, depending on the degree of lucidity politically feasible for particular policy situations. Planners might want to formulate deliberately ambiguous policy concepts and let precise meanings evolve out…

Introduces the "Pet and Me" project, a thematic unit that explores the relationships among humans, other animals, and nature. Provides the definition of thematic units by focusing on three levels of thinking: facts and information, topics, and themes. Concludes that the thematic unit is applicable to other areas of curriculum. (MOK)

After a brief critique of behaviorist pedagogical assumptions that learning is something done to learners, constructivist learning theory is presented as a framework for understanding experiential education, in that learning is a process involving the active engagement of learners, who adapt the educative event to fit, and expand, their individual…
