To analyze the relationship of logical development and comprehension of syntax, 60 children aged 5-8 years were individually tested. Measures included class inclusion, conservation of substance and weight, a sorting test, and a test of comprehension of active and passive sentences. Class inclusion was not strongly related to syntactical…

Results indicated that the training method (discrimination) induced 8 of the 12 subjects to acquire conservation of a stable kind. (Author/DR)

Topics briefly discussed include awareness or consciousness, recollection, reconstitution, and conceptualization; the nature of causal exploration and contradiction; and conservation. Examples are provided in relation to children's perception. For related articles, see TM 501 289 and 290. (RC)

Presents two studies which investigated the importance of subtle contexture factors on the young child's performance on cognitive problems--specifically, conservation. (ST)

This study investigates the relationships between the ITPA, which measures the development of specific language abilities, and the CAK, which is the most readily available measure of the development of conservation, in a sample of non-pathological preschool children. (Author)

The paper describes an experiment in which 52 deaf children (7-19 years old) and 36 normal hearing children (7-16 years old) were given several Piagetian conservation tasks to determine if the conventional instructions are the basis for conservation failure in deaf children and to examine the order in which deaf Ss acquired various forms of…

In two experiments (N=210) conservers, transitional conservers, and nonconservers were directed to lie or pretend to other children that their judgments and explanations of a series of conservation problems were the opposite of what they really were. Nonconservers and transitional subjects in both studies made large and significant gains in…

It was hypothesized that the acquisition of conservation behavior would be facilitated when stimuli were more concrete than abstract. Eighty white second graders were randomly assigned to four groups and presented with three conservation-of-weight problems. Clay balls and the conservation transformations were either shown, demonstrated, and…

Forty-eight kindergarten children were divided into four groups on the basis of their status (preoperational vs. transitional) and whether or not they received inversion-negation training. Results indicated no differences due to status, but differences due to training. Results do not confirm the contention that acceleration can only occur during…

The purpose of the present study was to determine if a developmental sequence could be established for the appearance of conservation. A series of four dimensional tasks and a conservation task were administered to 25 kindergarten girls and 25 kindergarten boys. The dimensional tasks tested understanding of comparative and superlative terms along…

This paper examines recent research for differences on rate of conservation achievement between the subcultures: (1) rural vs. urban-suburban, (2) white vs. black, (3) subculture of poverty vs. middle class WASP, and (4) lower vs. middle socioeconomic status. The author concluded from his examination of research that: (1) among middle-class whites…

The author examines Novak's position that science and mathematics educators should discard Piaget's theory of intellectual development in favor of Ausubel's theory of meaningful learning as a guide for teaching practice and research. (PB)
