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…

This study investigated the relationships among mathematics achievement scores of first graders, the order of presentation of difficult topics, the use of readiness activities, and scores on a conservation test. The study was developed and conducted in four phases. Phase 1 included analysis of 70 randomly selected first-graders' work on the…

The use of equivalent-age children as tutors was investigated, and the cognitive changes of these tutors was examined. All first and second grade boys at two elementary schools were administered a pretest, and all those in a transitional stage of development between non-conservation and conservation of substance were selected for inclusion in the…

This study was based on the following assumptions: (1) functioning of the brain's left hemisphere, because of its logical, verbal mode, facilitates conservation reasoning; (2) functioning of the brain's right hemisphere, because of its nonverbal, spatial mode, inhibits conservation reasoning; (3) visual input from the left eye will reach the left…

First, second, third, sixth, and ninth graders and college students were presented with 4 different tasks of surface-volume dissociation in order to see whether or not the conservation of one of these properties would wrongly induce a belief in the conservation of the other. (Author/JMB)

A study was undertaken of the effects of formal education and conservation of numerousness on addition and subtraction problem types. Thirty-six kindergarten and 36 first-grade subjects randomly selected from one area of a school district were administered measures of conservation, problem-solving success, and modeling ability. Following factor…

In this paper the author reviews and synthesizes the research literature concerning the developmental relationships between conservation of number and linguistic capability in handling of quantitative and relational terms. Several models for the development of these competencies are discussed. On the basis of this review the author concludes that…

This study investigated the linguistic components of Piaget's class-inclusion task. First, hierarchical classification is examined from both Piagetian and linguistic theory points of view. Then, two general characteristics of child thinking that relate to the different interpretations of the responses to classification questions are discussed: (1)…

Implications of this study on child-development theory, education, and psychotherapy are discussed. (MB)

Attainment relative to six cognitive operations and four number and computational skills was assessed for 90 elementary students using clinical procedures. Variance associated with conservation of number, seriation, and logical classification competency accounted for a significant proportion of the variance in achievement scores. (Author/MK)

This study investigated the relationship between the level of conservation of displaced volume and the degree to which sixth graders learn the volume algorithm of a cuboid, i.e., volume = length x width x height (v = l x w x h). The problem is a consequence of an apparent discrepancy between the present school programs and the theory of Piaget…
