Investigates the development of understanding of quantity in 36 children with Down's Syndrome. Findings confirmed similarities in sequence of development between Down's Syndrome children and nonretarded children. Down's children who received training recognized conservation of continuous and discontinuous quantity. (RJC)

Discusses past research involving Piagetian conservation concepts in Native American students; the relation of language to mathematics education; holism in mathematics learning; mathematics and culture; the Outdoor World Science and Mathematics Project, which developed learning modules involving Native Americans; and mentorship in an atmosphere of…

This activity explains fisheries resource management to seven-year olds. First-grade students learn concepts such as offspring viability, life expectancy, and distribution of species, which help to determine when, where, and how people fish and the importance of fishing responsibly. Lists materials, procedures, and extensions. (SJR)

A lot of good elementary science involves studying solids, liquids, and gases, and some inquiry-based activities that are easy to set up and do. In this article, the author presents activities pertaining to simple phase change. Using water as the example, these activities introduce upper-grade students to the idea of the arrangement of molecules…

Forty-four middle and 44 lower SES children were given Piaget's provoked and spontaneous correspondence tests to see: (1) how they made correspondence, (2) if the idea of equivalent sets, once achieved, was retained after objects were regrouped destroying visible equivalence, and (3) if age, sex, and SES differences existed. Results indicated that…

Compared institutionalized and public school retardates to normal elementary and high school students at several mental age levels on three conservation of weight tasks. (Author/SDH)

This study sought to identify prerequiste concepts for a child to perform length measurement meaningfully. Conservation of length and use of transitive reasoning were major areas identified. Implications for teaching are given, especially concerning the use of a number line as a model for presenting arithmetic operations. (LS)

Provides data indicating that development occurs in cycles, with behavioral competencies appearing and developing and then disappearing only to reappear again in a more complex form at a later age. Data on conservation and auditory-manual coordination in infancy are used to support this theory. (ED)

This study compared the effects of a formal, an open-framework, and a control preschool program on children's intellectual development. The formal program, based on Ausubel's and Piaget's theories, had a daily schedule of short prescriptive teaching sessions followed by related learning activities. The informal program, based on Piaget's theory,…

The purpose of this study was to examine the relationships of children's performance on the Torrance Tests of Creative Thinking (TTCT) and on selected Piagetian tasks of conservation. Study subjects, 133 kindergarten and first grade multi-racial boys and girls, were administered the TTCT-Figural Form A and selected Piagetian tasks of conservation…

The comparative school readiness and cognitive ability of kindergarten children from lower-income schools (N=47) and from higher-income schools (N=71) were assessed using the Preschool Inventory and a battery of eight Piagetian tasks. The overall purpose of the study was to ascertain characteristics of the children's cognitive development as a…

TO DETERMINE HOW TRAINING WOULD AFFECT CHILDREN FROM DIFFERENT LEVELS OF DEVELOPMENT, FIVE DISADVANTAGED AND FIVE ADVANTAGED PRESCHOOLERS WERE GIVEN SPECIFIC PROBLEM SOLVING TRAINING TO PREPARE TO SOLVE A CRITERION PROBLEM. THIS STUDY WAS AN ATTEMPT TO DISPROVE PIAGET'S THEORY THAT CHILDREN MUST HAVE REACHED A CERTAIN STAGE OF CONCRETE-OPERATIONAL…

Longitudinal support was obtained for a positive relationship between cognitive and social development. From a large sample of kindergarteners, three groups of 12 children of comparable age and IQ were selected as displaying substantial, moderate, or no mastery of Piagetian concrete operations. From kindergarten through second grade, the social…
