Investigated was the distinction between identity conservation and equivalence conservation in 180 preschool, kindergarten and third grade students. Ss were assigned to one of six different counterbalanced orders of presentation for the conservation task battery. The factors were age, task (identity/equivalence), criterion (judgment only/judgment…

This study is a longitudinal follow-up analysis of children's performances on a number of Piagetian concrete operations tasks dealing with conservation and transitive inference. Subjects were 102 children selected from kindergarten and grades 1, 3, and 4. (Author/MP)

Attempts to apply Piagetian theory and research to educational settings are reviewed and evaluated. The fundamental assumptions of Piagetian theory are briefly summarized and the educational philosophy of Piaget is presented. Five representative early childhood education programs (as designed by Lavatelli, Weikart, Kamii, and DeVries, Furth and…

As an integral step in a comprehensive, four year longitudinal analysis of concept development, a series of logical concept tasks based upon Piagetian theory, and suitable for administration to individuals five years of age or older, are described. The developmental focus was the logical groupements associated with the concrete operations period…

Kindergarten and third grade children originally assessed in 1973 were retested one year later on a series of conservation and transitive inference tasks (length and weight content areas). An additional sample of matched cohort/grade subjects was assessed in the second year only to permit evaluation of repeat measurement biases for the…

Two experiments which investigated the young child's ability to deal with multiplicative classes and relations (considered behavioral indices of concrete operations thought) in double series and cross class matrices are described and discussed. In the initial study, 160 children from preschool through grade 2 received six matrix subtasks…

A series of Piagetian concrete operations period tasks dealing with classificatory concepts was administered to 280 children (40 subjects from each of seven levels--preschool, kindergarten, and first, second, third, fourth, and sixth grades). Significant main effects for age were found for all the tasks. Few significant sex differences were…

This report is the initial overall summary of a comprehensive analysis of children's logical concept attainments and memoric abilities and deals exclusively with the initial and second year's assessment data. The focal point for this normative investigation is the concrete operations period spanning the years of middle childhood. The measurement…

This 4-year longitudinal study of logical reasoning found complex interrelationships among different cognitive processes of children ages 6 to 15. Piaget's stage theory is discussed in the introduction, with a focus on the concrete operational stage in middle childhood. In the study, a representative array of logical concept tasks and short-term…

Assesses 180 college students at three ages (17-23, 37-43, and 61-80) to examine the relative availability of Piagetian formal reasoning concepts; the relationship of these formal reasoning performances to Horn and Cattell's psychometric theory of general fluid and crystallized intelligence; and developmental patterns among standardized…

While the purpose of this project was curriculum development, long range benefits are contingent upon a radical reorganization and upgrading of public school systems throughout Appalachia. Subjects in the pilot assessment consisted of 80 children (3 1/2 to 6 1/2 years old) and their mothers from each of Monongalia and Upshur Counties, West…
