The multiordinal use of terms requires the ability to distinguish essential relationships and attributes from incidental ones. Until the child reaches adolescence, his tendency to confuse incidental and affective factors with those crucial to word meaning hinders his use of terms at all levels of abstraction. Korzybski's theory of multiordinality…

In this study of perspective taking and moral judgment 20 children (10 boys and 10 girls) at each age level between 4 and 10 years were given Feffer's Social Role-Taking Task, a spatial perspective-taking task and Damon's Test of Positive Justice. Investigated were: (1) the specific developmental sequences for role taking, spatial…

This study explored the relationship between the mother-infant interaction and the concurrent perceptual-cognitive and intellectual status of the infant. One hundred and eight-nine 12-week-old infants were given a battery of perceptual-cognitive tasks, including the Mental Developmental Index (MDI) of the Bayley Scales, the Corman-Escalona Scales…

Originally designed for inner city children, ages 3-5 years, "Sesame Street" was designed to increase knowledge in the areas of: symbolic representation (pre-reading skills), cognitive organization which entails relational concepts, reasoning and problem solving, and the child and his world. This study examined the effects of the program…

Investigated was the compatibility between the intellectual abilities of students and the level of intellectual operations required by secondary level physics textbooks. Student intellectual levels were determined for 949 tenth-, eleventh-, and twelfth-grade students by administration of Piagetian tasks. Major concepts presented in physics…

This article states that children in the first grade have usually not developed the thought processes which would enable them to understand the typical first-grade math curriculum. (CD)

Discusses some advantages of multi-age grouping in group child care centers. (ED)

Discussed is the parents' role in providing training procedures to meet the developmental needs of blind infants. (Author/LS)

The teacher of mathematics or science must be aware of the concepts, facts, and generalizations of his field, of psychological principles of learning, and of teaching methods. Methods appropriate to the teaching of concepts differ from methods for teaching generalizations. (SD)

Teaching is not an activity directly producing the learning of some specific matter (which is inadequate as a definition of teaching and incapable of being guaranteed), but an activity intentionally directed toward, and potentially capable of, improving the student's general intellectual functioning or "cognitive competence" in whatever…

The existence of a time lag discovered in the cross-cultural application of Piagetian tests may result from a socio-economic bias in Piaget's theory. Abstract, formal cognition may reflect a particular social structure, embodying the principles of exchange value, reification, and alienation which govern production and exchange in the…

Research findings related to children's concepts of length, area, volume, weight and time are reviewed. Implications for instruction in measurement of these qualities are discussed. (SD)

Focuses on studies related to Piaget's specifications for secondary student's development from concrete to formal level thinking. Discusses three problem areas in Piagetian analysis: (1) specification of logical formal thought model, (2) underlying assumptions, and (3) empirical findings. Comments on application problems. Assesses Piagetian…
