To examine the characteristics of expertise, a study at the University of Minnesota cardiac clinic compared differences in diagnostic ability and strategies between novices (fourth year medical students) and experts (specialists in pediatric cardiology). The investigator presented a model for expertise based on knowledge of subject matter content…

This study assesses the effects of visual and verbal rehearsal on the problem solving efficiency of preschool children. The study examines the use of stimulus pretraining designed to induce verbal rehearsal and compares the effectiveness of induced verbal rehearsal with the effectiveness of induced visual rehearsal. Fifty-four middle class…

Traces the problems teachers solve as they learn to teach writing and reading from the same philosophical perspective. Finds that as the emphasis in their classrooms shifted more to the process, the teachers changed their roles. (FL)

Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…

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)

Discusses the use of artificial intelligence to improve occupational instruction in complex subjects with high performance goals, such as those required for high-technology jobs. Highlights include intelligent computer assisted instruction, examples in space technology training, intelligent simulation environments, and the need for adult training…

Discussion of the use of computerized databases in classroom instruction focuses on problem solving skills, student attitudes toward computers, and learning processes. A study of eighth graders is described that tested hypotheses involving the comparative analysis of data, and its implications for curriculum development and instructional methods…

Advocates the use of discovery or guided inquiry experiments for developing critical thinking in problem solving. Provides a stepwise method for creating inquiry experiments and provides an example by comparing the two methods for a freezing point experiment. (JM)

This handbook brings together important mathematics education research that makes a difference in both theory and practice, research that anticipates problems and necessary knowledge before they become impediments to progress, interprets future-oriented problems into researchable issues, presents the implications of research and theory development…

The problem-solving approach to teaching and learning has proved especially useful in vocational education as a way to relate classroom learning to real-life situations or problems. The problem-solving method of teaching places the responsibility for learning on students. Educators and special reform groups in other subject areas refer to a…

Two experiments examined the relationship between reasoning skills, student grade, ability, and knowledge levels. Findings were interpreted in terms of a two-component model: a knowledge-experiential component and the conventions of reasoning. Results indicated that consideration of the relation of reasoning to learning and to instruction…

Describes a systematic instructional process that incorporates the general steps of problem solving to develop a World Wide Web-based independent study course. Highlights include the educational setting, learner characteristics, method of assessment, learning processes, course assignments, interaction between faculty and students, course content,…

Interprets and contrasts children's mathematical interaction from the points of view of radical constructivism and of Soviet activity theory. Proposes a superseding model based on the interrelations between the basic sequence of actions and perturbation and the interaction of constructs. Supports the model by describing how children used…

Proposes a new model of children's mathematics by composing aspects of the Fraction Project and critiques presented in the same issue. Argues that computer microworlds provide children with dynamic learning environments in which they are the primary actors and teachers with a medium for interact with children's mathematics while trying to maintain…

Three learning activities--story generation, reasoning from historical information, and computer modeling--that are designed to help students move toward a more coherent understanding of biological mechanisms are described. A method used to measure a student's level of understanding and their progress during instruction is also described. Ways to…
