Investigated methods science and nonscience majors use to make predictions about five situations involving the conservation of mechanical energy. Two findings, among others, show that subjects did not employ identifiable strategies in over 97 percent of the cases and show differences in the way majors and nonmajors worked the problems given.…

Considers research concentrating on the correlation between knowledge structure and learning. Suggests implications of this research to classroom teaching. Cites characteristics of unsuccessful and successful problem solvers. (RT)

Describes teaching strategies that help students improve problem solving skills. Lists three factors good problem solvers were found to possess. Gives step by step instructions for solving problems. (MVL)

Examines various types of problems that researchers have used to demonstrate problem solving. Focuses on genetics problems. Discusses classes of learning outcomes, conceptual knowledge gains, content-independent heuristics, content-specific procedures, understanding the nature of science and a typology of genetics problems. (CW)

Examines the hypothesis that there are preliminary stages in problem solving that are often neglected in teaching chemistry. Discusses correlations calculated between the student's ability to handle disembedding and cognitive restructuring tasks in the spatial domain and ability to solve chemistry problems. (TW)

A number of studies have reported that there is a strong tendency to ignore base-rate information in favor of individuating information, except when the former can readily be incorporated into a causal schema. In this study, students in eight undergraduate classes were given problems in which the base-rate information was either causal or…

Describes the novice-to-expert model of human learning and compares it to the recent advances in the areas of artificial intelligence and expert systems. Discusses some of the characteristics of experts, proposing connections between them with expert systems and theories of left-right brain functions. (TW)

Differentiates between learning efficiency (enhancing the rate of learning) and learning effectiveness (enhancing the mastery and retention of facts, concepts, and relationships). Discusses some of the contributions of knowledge engineering to metalearning. Provides a concept map for constructing knowledge bases, along with some possible…
