Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students' interests in participating in opportunities to do real science? What are the discursive "resources" they draw on to introduce authentic science to students? The purpose of…

Presents a teacher's reflection on his teaching using two different perspectives. The first perspective uses the cognitive apprenticeship metaphor as a tool for analyzing and understanding teaching. The second, a methodological perspective, uses conversational analysis to arrive at microanalytic descriptions and conceptualizations of teaching. (PR)

Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)

Over the past several years, an increasing number of educators have come to believe that teaching should acknowledge the transactional nature of knowledge and suggest that a shift be made to focus on social practice, meaning, and patterns. This style of teaching proposes that it is important to permit students to construct knowledge meaningfully…

Examines the relationship of the amount of available short-term memory with the complexity of tasks the subjects mastered. Presents some hints for a better design of instruction. (YP)

Provides an example of the integration of science and mathematics learning of one high school physics student in a constructivist classroom. Discusses the student's integration of mathematical and nonmathematical representations and of different mathematical representations in a nonuniform acceleration experiment. Describes a model for integrating…

Examined is the predictive value of the cognitive variables of developmental level, mental capacity, cognitive style, short-term storage space, and numerical inductive reasoning for student achievement in college science. Included is a strategy for the development of materials which would allow students to develop problem-solving skills. (KR)

Conducted an ethnography to evaluate the usefulness of the notion of community of practice in classroom settings. Documents how collectively available knowledge of a classroom community was transformed as resources and practices were adopted by more and more members. Discusses implications for the organization of classroom environments that…

The present study was designed to test how well the measures of the cognitive constructs of M-space, cognitive style, and short-term storage space (STSS) could predict the amount of practice needed to induce successful problem solving behaviors, the ability to transfer behaviors to different contexts, and the readiness to abandon unsuccessful…
