Reports on a study designed to examine the effect of concrete and formal instruction upon reasoning and science achievement of sixth grade students. Results indicated that the concrete instruction group had significantly higher levels of performance in science achievement and cognitive development and that males outperformed females. (TW)

Argues for an approach to undergraduate instruction that incorporates recent research concerning schema theory (the continual cognitive restructuring and processing of information). Recommends beginning with fundamental skills and building on these to include more complex concepts and processes. Includes an illustrative example beginning with…

Discussed are possible reasons behind the inconsistencies in the learning of calculus. Implicated are students' beliefs, mathematical paradigms including concept image and concept definition, language use, and curriculum sequencing. (KR)

Discussed are the issues of inconsistencies and compartmentalization and the use of inconsistencies in the classroom. Included are discussions on paradoxes, the naive student, logical reasoning ability, and the development of the students' cognitive structures. (KR)

Discusses a system of classification for students' inconsistent ideas in mathematics, the sources of students' mathematical inconsistency, and instructional strategies for helping students to resolve apparent learning inconsistencies. Language, curriculum, and instruction are included in the discussion. (KR)

Discusses recent research in cognitive psychology that identifies how students are likely to respond when controversial issues are included in course content. Points out that controversial material may lead to misunderstandings and forgetting. Provides teaching ideas to enhance student learning and remembering, to deal with emotions, and to foster…

Evaluates present conditions and recognizes current methodology being used for rule-based systems and schema-based systems, and gives examples of these systems. Lists educational implications of artificial intelligence and expert systems. (MVL)

Summarizes and illustrates the knowledge-based approach to instructional material design. A series of sports coaching handbooks and hypermedia presentations of the same material are described and the different instantiations of the knowledge and training structures are compared. Figures show knowledge structures for badminton and the architecture…

Reports on an exploratory study of a metacognitive approach to teaching low achieving secondary students. Asserts that the research team hoped to examine a process whereby a dialog about learning processes would develop. Finds that all students indicated that they were able to focus on learning as a topic of conversation. (CFR)

Reports case studies using personal construct psychology and the logic of fuzzy sets to elucidate the content and organization of two elementary school teachers' knowledge of fractions and mathematical pedagogy. Results identified four personal constructions that affected classroom events; knowledge of fractions, general pedagogical knowledge,…

Describes a study of high school students that examined responses to a music video dealing with teenage pregnancy. Students' motivations for viewing music videos, experiences with sex and pregnancy, and family communication patterns are related to the cognitive activities of thinking about the video content and relating it to their own lives.

Reports a study examining the concurrent validity of concept maps as vehicles for documenting and exploring conceptual change in biology. Elementary education science methods students who were instructed on marine life zones showed significant differences on their concept maps on this topic. (PR)

Presents a concise introduction and overview of "constructivism." Constructivists assert that knowledge is constructed by individuals; constructivists advocate classroom procedures that encourage students to identify the subjectivity and biases of existing interpretations and to arrive at their own conclusions. Examines four hypothetical teacher…

This study examined the subject-pedagogical content knowledge transformation process associated with middle school physical education teachers' curricular decision making. Findings indicated that teachers shared a common subject content knowledge base but demonstrated personalized pedagogical content knowledge repertoires. Classroom curriculum was…
