Examines processes by which general but weak search methods are transformed into powerful, domain-specific search strategies by classifying types of heuristics learning that can occur and components that contribute to such learning. A learning system--SAGE.2--and its structure, behavior in different domains, and future directions are explored. (36…

Argues against the merely descriptive presentation frequently used in teaching biochemistry and in favor of a constructivist approach called heuristic-teleonomic, which unites the process of discovery with adaptation to functional ends. Discusses difficulties inherent to the nature of biochemistry, including the conflict between acquiring…

Maintains that there is a lack of research on teaching styles and that teaching and learning styles are distinct topics and should be studied separately.
