This study investigated the relationships between symbolic play, reading readiness, drawing, Piaget's principle of conservation, and age, in 41 preschool children. Subjects were participants in a pre-first-grade summer program; they had had kindergarten experience but no formal reading instruction, and they ranged in age from five years, six…

A study was made to assess the extent to which social interaction is beneficial to cognitive development. A total of 154 boys and girls, 5 through 9 years of age, initially participated individually in a conservation-like pretest requiring prediction of the way a beam would tip when different numbers of weights were placed at differing distances…

Analysis of 65 children over a 4-year period on tests of operational and causal thinking offers support for Piaget's notion of stage progression. In kindergarten and grade one, the majority of children in this longitudinal study were between preoperational and the achievement stage of operational thought. By grade two, the majority had attained…

Appraises the respective contribution of initial competence and of imitation of modeled response in the observational learning of conservation among first grade children. (HOD)

Two experiments were designed to investigate among kindergarten through third-grade children the development of character constancy -- the belief that other's or self's personality characteristics are stable across time and do not change despite changes in appearance. It is proposed that character constancy of self and other is a product of both…

Kindergartners who received learning-set instruction on unidimensional classification, unidimensional seriation, and number conservation were retested at the end of first grade. Followup tests showed that the cognitive advantage and improved academic achievement gained from that teaching method was generally present 15 months later. However, a…

Israeli children's (kindergarten to grade nine) explanations about the water cycle are described. Reports the children's views about the source of clouds and the mechanism of rainfall. It was concluded that understanding evaporation is a necessary condition for explaining a mechanism of rain containing the ideas of condensation and heaviness. (YP)

A study was conducted to investigate the respective contributions of personal and social factors (initial competence and imitation of modeled responses) in children's observational learning of conservation. Subjects included 180 first-grade nonconservers from six schools attended by French-speaking middle class pupils. All subjects failed…

A study was designed to develop an instrument and methodological procedure to assess transitive relations within seriation problems in elementary school children using three criteria: explanations, judgments, and strategies. A secondary analysis to assess transitivity used the three criteria according to whether the children were conservers, in…

Documents cognitive processes mediating the observational learning of conservation. Findings suggest the presence of demand characteristics for high undifferentiated ratings under a public format of certainty appraisal. This contamination prevents valid monitoring of the course of cognitive rule processing. (RH)

A longitudinal investigation was conducted on the development of conservation skills in learning disabled (LD) children. During each of 3 years, six measures of conservation from the Concept Assessment Kit (space, number, substance, weight, continuous quantity, and discontinuous quantity) were administered to 31 newly identified LD students and 33…

This study investigated: (1) the relationship between the development of information processing capacity and certain Piagetian logical reasoning abilities; and (2) how the development of these cognitive abilities related to acquisition of certain measurement concepts. Forty first-grade children were individually administered tests of conservation…

Describes longitudinal study of the development of understanding of two logical properties of number by 36 children during the first three years of primary school in Glasgow. Piagetian tests and number skills tests were administered to explore the acquisition of number as class and number as order concepts. (Author/LRW)

To investigate whether children who had been in a bilingual instructional program for three years or less would have some cognitive advantages over those in monolingual programs, 96 (50 percent male, 50 percent female) first to third graders from Edmonton (Alberta) were tested in 1979. The children in bilingual programs outperformed their…

The cutoff method was used on longitudinal data in more than one content domain in a study attempting to determine whether the effects of schooling are general or limited. Conservation of number, an informally acquired skill, and mental addition, a formally acquired skill, were evaluated among older kindergarten children, younger 1st-grade…
