All contemporary learning theorists agree on the advantages of involving students in authentic problem-solving activities in both in-school and out-of-school contexts. Approaches which use real-world problems as learning tools fit well with: (1) the strategy-based, performance model advanced by information processors; (2) the impasse or…

Experiments on the cognitive and perceptual development of three- to seven-year-old Soviet children are described, especially the work of L. A. Venger, N. N. Poddyakov, and D. B. El'Konin. Visual-action and visual-image thinking are illustrated. (GDC)

Piaget's theory of space perception is presented in the format of a hypothetico-deductive system.

Critical notes are inserted and general conclusions are briefly discussed.…

Three-dimensional (3-D) aerial photographs viewed with cardboard filter glasses (anaglyphs) aid elementary and junior high school students in recognizing physical features, offer a realistic vertical perspective, and have motivational values. A review of research on cognition, perception, and the use of anaglyphs reveals that pictures are an…

A review is presented of research findings on the operation and functions of the two hemispheres of the brain. In tracing discoveries on hemispheric specialization (the left processing information objectively, linguistically, and linearly; the right, spacially, intuitively, and creatively) the importance of achieving a balance between the…
