The present study was designed to assess the effectiveness of certain cognitive training tasks on children in group settings under natural preschool conditions. Thirty-five children, aged 47-63 months, were divided into six experimental groups and received various cognitive tasks. Results indicated that most children experienced at least moderate…

The objective of this study was to assess the ability of a previously prepared diagnostic test to detect the need for remediation in preschool children and then to assess the effectiveness of specially designed remedial materials. The subjects consisted of 47 boys and 25 girls from four private kindergartens in Nashville, Tennessee. All subjects…

The Piagetian operations of multiple classification, multiple attributes, seriation and reversibility were used to develop an "equilibrated methodology" to help preschool children conserve quantity. Randomly assigned experimental and control groups within morning and afternoon classes at a nursery school were used to evaluate the…

Reported are the results of an investigation of the child's acquisition of the concept of area measure. To measure this acquisition, four axioms were developed to define the concept of area. A task was developed for each axiom to test operational understanding of the axiom. A test of vocabulary and a conservation of area task were administered to…

The purpose was to investigate the influence of variations in conservation form and perceptual modality on the expressed level of understanding of the conservation of weight concept, and to determine if these variations result in significantly different observed rates of concept development. Sampling included 225 children, five to twelve years…

This study investigated the development of time concepts, comparing children of Afro-American and Anglo-American ethnic groups with each other and with results obtained by Piaget. A sample of 120 children aged seven, nine, and eleven years from one school were individually administered four time conservation tests (two on simultaneity and two on…

The purposes of this study were to determine the feasibility of group testing of conservation and examine the differential performance of students drawn from various populations. The effects of three factors were examined: grade level (2, 4, 6), SES (disadvantaged, advantaged, and race (Black, White, Latin). (Author)

The goal of this study was to investigate improvement in the usage of equivalence and order relations under specified instructional conditions. Forty-eight upper middle class kindergarten children were given a 14-session pretreatment designed to define two equivalence and four order relations of length and matching, followed by tests of…

Tested was a method of learning numeration, addition, and subtraction using measuring operations in place of the more usual counting operations. It is claimed that an approach through "units of measurement" to continuous variables is mathematically more powerful than counting, which leads only to nominal and ordinal variables. Twelve children…

Suggests that although Piaget's psychological theory is developmental and dialectical in a general way, the lack of a developed philosophical basis leads to the subordination of a dialectical approach to static, anti-dialectical concepts. Hegel's theory of interaction and contradiction is examined to show that dialectical theory has a precise…

Kindergarten through fourth graders (N=170) were tested for conservation and then interviewed following the presentation of a story about an elderly woman's death, in an attempt to assess children's understanding of 3 concepts: irrevocability, cessation of bodily processes, and universality. (Author/JMB)

Presents a study of the development of conservation of weight among socially deviant adolescents. (BD)

Examined the relationship of ability to conserve and comprehend of logical riddles in 33 first-, third- and fifth-grade boys of average intelligence. Although both riddle comprehension and cognitive maturity as assessed by Piagetian tasks increased with grade, the relation between them was not clearly demonstrated. (Author/JMB)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

Two experiments investigated the relative efficacy of two conservation training procedures and the transfer of training to another type of conservation. (SB)
