Describes how three biology textbooks present content related to photosynthesis through construct of elaboration. Concept maps were created for each textbook. Results are discussed in terms of quantity of elaboration, relevance of ideas used to elaborate major concepts, relationship of nature of elaboration to intended readers, and general…

Interviews were conducted with grade 10 students (n=34) who had received 4 years of physics instruction. Interview's focus was to understand students' responses from their point of view. The results of the study confirm and deepen findings from other studies concerning students' severe difficulties in learning the energy concept, the particle…

The purpose of this study involving 12 classrooms was twofold: (1) to understand the conceptual frameworks that sixth-grade students use to explain the nature of matter and molecules, and (2) to assess the effectiveness of 2 alternative curriculum units in promoting students' scientific understanding. Results reveal that students' entering…

Changing ideas about the origin of the Silurian Clinton oolitic ironstones in eastern United States provide an instructive example of how interpretations develop as knowledge increases. (PR)

Synthesizes quantitatively the experimental and quasi-experimental research in reading education and science education designed to test the effects of various instructional interventions on misconceptions. Identifies specific strategies or approaches that were effective in producing conceptual change. Notes that effective procedures had a common…

This paper describes common practices in social studies instruction and proposes a conceptually based model of history instruction for learning-disabled students, involving sameness analysis and integrating concepts into a network of knowledge. The model includes preskill instruction, problem-solution-effect analysis and note taking, vocabulary…

Discussed is a constructivist model of science learning and its possible use in the treatment of science misconceptions. Science learning as conceptual and methodological change is described. (KR)

Based on the premise that body experiences interfere inconveniently with scientific ideas in mechanics instruction. Suggests that learning processes start with body experiences and, with guidance, transform them into something scientific. Discusses this process for the static and kinetic aspects of force and for measurement. (MDH)

A theoretical discussion of categorization, unit structures and structured units, and fractions as operators was introduced. The thinking of grade-three students (n=3) with regard to the meaning of fractions was investigated in two teaching episodes using the computer environments of SuperPaint and CopyCat. (Contains 14 references.) (MKR)

Raises questions regarding what students are perceiving when concrete models are used to represent abstract scientific concepts. Discussion of several exploratory investigations on the role of models in science teaching is presented in three areas: (1) interactions with students; (2) effectiveness of models; and (3) spatial ability and models.…

Describes a study of factors in the development of reasoning on the balance beam (n=34 nonscience majors in a Physical Science class). From this study and others, the author developed a model of problem solving and problem-solving behaviors. The implications of this model for instruction are discussed. (PR)

Presents follow-up activities to learning scientific concepts that utilize concepts from books obtained from the school library. Suggests seven books and related science activities involving shadows, force, animals, nature, dinosaurs, machines, and mirror reflections. (Contains 10 references.) (MDH)

Explores the views of Japanese students (N=2478) concerning the nature of science, technology, and society via a questionnaire. Discusses the results within the context of Japanese culture. (DDR)

Explains the work of a primary-research group focusing on the practical aspects of the use of scale in science. Reports on three studies that look at the impact of the representation of scale in different areas related to the Standard Assessment Tasks (SAT). (DDR)

Focuses on the use of a science-based topic with children ages six and seven to explore ideas for developing children's use of descriptive language. Employs talk partners and circle time as strategies for developing language. (DDR)
