This document contains lesson plans for teaching the left-right relational concept to preschool children. Procedures were designed from a Piagetian framework, so that cognitive conflict was considered a necessary condition for the evolution of transpositional skills. Conflicting viewpoints were instituted through teacher initiated peer…

The purpose of the study was to determine whether kindergarten children could perform successfully on Piagetian class inclusion tasks and whether their performance was a function of the types of conditions under which the task was presented. Children were asked to classify items based on a physical attribute not visually perceptible (painted…

This paper is a refinement of a model of conceptual learning and development presented initially as the Presidential Address to Division 15, Educational Psychology, of the American Psychological Association in September 1971 at Washington, D.C. Thus it supersedes the initial formulation in explicitness and detail. This paper explains the nature of…

Three systems for defining cognitive abilities, proposed by Guilford, Guttman, and the Thurstones, are examined as bases for specifying reference tests for cognitive abilities. The authors propose the cognition of concepts system as a fourth alternative. Tests constructed and/or adapted on the basis of this examination are described. (Author)

The ontological problem is "what exists?" The answer regarding the part of consciousness which is related to left hemisphere is that only individual discrete objects exist; objects are regarded one at a time. The answer regarding the part of consciousness which is related to right hemisphere is only comprehensive entities exist; each…

Discusses five- and six-year-old children's conceptions of life and death. Children were questioned about animals, plants, and inanimate objects. The most errors occurred when children judged inanimate objects; the fewest when they judged animals. The order of questions about either life or death significantly influenced children's responses.

Children (N=32) between 6 and 12 years of age were given Derry Death Concept Scale, Peabody Picture Vocabulary Test, and subtests from Wechsler Intelligence Scale for Children-Revised. Correlations indicated that level of death concept development was related to age and verbal-conceptual mental development. Socioeconomic status and death-related…

Support for the operation of internal factors in cognitive development was provided by an obtained increase from first to second posttest scores. Two conservations were considered to be involved--conservation of the whole and of the part. (Author)

Investigates the developmental priority of identity conservation as contrasted with equivalence conservation using quantity and number conservation tasks. (Author/AJ)

Results support view that development of part-whole perception is mediated by logiclike perceptual regulations. (MH)

This study based on a PhD dissertation submitted to Wayne State University, indicates a "conceptual distinction within conventional Pigetian conservation tasks...The results indicate that identity conservation is developmentally prior to equivalence conservation. (Author)

Suggests practical applications of Piagetian theory to reading instruction. (FL)

The LD first graders were found to have a lower level as well as greater variability in their understanding of basic concepts. The greatest discrepancy of the LD group was found on concepts of quantity, space, and miscellaneous, respectively. (Author)
