Students' preferences changed from applied to theoretical aspects of physics, and from recall of facts to identification of fundamental principles during two years of study of the Physical Science Study Committee in Australian High Schools. (AL)

Study concerned with the mechanisms in terms of which the developmental transformation from one cognitive structure to another occurs. (Author)

Piaget's theory of developmental stages was implemented in an elementary school curriculum. Some successful learning experiences are described. (CP)

Presents a satirical prediction of developments and trends in the treatment of dyslexia, in the study of the perceptually handicapped, and in linguistics for 1980. (MD)

Explains Piaget's concepts of "subject-object" and "subsystem" interactions in problem solving and describes a test that substantiates Piaget's hypothesis and points to antecedent conditions that appear to stimulate imaginal structures. (SB)

The rigidity construct is reinterpreted in terms of the cognitive developmental approach. A review reveals both cognitive and developmental themes, with an emphasis on the structural and operational properties of rigidity. Notes weaknesses of previous approaches to rigidity and discusses implications and predictions from the proposed model.…

Analyzes the developmental patterns in the production of analogy by second-, fourth-, and sixth-grade students to determine whether children use different types of analogy as they achieve linguistic maturity. (HOD)

Reviews and synthesizes the major findings on reversal errors made by young readers. (FL)

Piaget's theory of cognitive motivation is examined. Other Piagetian theories are also explored: the distinction between figurative and operative aspects of knowledge, and passivity versus activity. A limited set of implications of Piaget's theory and description of intellectual development for methods of active education are discussed. (CT)

First and fifth graders in two IQ groupings reconstructed pictures which were variations on a prototypic picture. In subsequent recognition, children gave confidence ratings on the "oldness" of the pictures. Prototypes were recognized with most confidence. Younger and lower IQ children were less sure about noncases being "new".…
