Compares the ages of intellectual development of conservation and reversibility concepts by gifted children with established norms. Study shows a substantial percentage of gifted children made abstract conceptions well ahead of children in general. Where the concepts of conservation and displacement of volume had not been grasped, students…

Sixty-one children in grades 1, 2, and 3 in rural county schools were compared in their semantic differential judgments of relational terms used in assessing conservation. (WY)

Three- to 7-year-old children were trained through reinforcement to select the more or less numerous of two rows of squares. All children successfully judged relative numerosity when number covaried with length or density, but only concrete operational children were successful when numbers did not covary with other dimensions.

Piaget's conservation paradigm was used to assess five- to seven-year-old children's understanding of the permanence of various kinship roles. Children's conservation was studied by applying certain transformations on single- and multiple-kinship role combinations. Kinship conservation developed gradually in this age range. Females' performance…

Attractive stimuli and fantasy instructions were used in an attempt to manipulate children's involvement in the outcomes of their number and liquid conservation judgments. (Author/DB)

The "magic" paradigm was devised to assess conservation of number in young children. Subjects were 32 three- to four-year-old children. (MP)

Investigates possible relations between the methods of quantification available to children and their performance on certain tasks requiring an understanding of number invariance. (Author/RK)

Reports on an exploratory study of the ideas that students in the fourth semester of engineering have about conservation. Reviews the Piagetian position on the importance of conservations in logical operational structures in child development. Discusses the development of conservations in science during the 17th, 18th, and 19th centuries and…

Tested was the hypothesis that science instruction based on task analysis will lead to the acquisition of the ability to perform certain Piaget volume tasks which have been characterized as requiring formal operations for their solutions. A Test on Formal Operations and a Learning Hierarchies Test were given to fourth- and sixth-grade students in…

This document describes experimental attempts to teach young children the concepts of conservation of number. Subjects were 48 nursery school children who were divided into experimental and control groups. All children were individually pretested for conservation, after which the experimental group alone received two training sessions. The…

In testing conservation of number in preschool children using both equality and inequality; 3- and 4-year-olds tended to use an acquiescence response set while 5- and 6-year-olds responded in terms of relative length. (ST)

It was concluded that movie presentation did not destroy the essence of the conservation task and that it gave promise of the development of an effective means of standardizing Piagetian testing when used in conjunction with a series of follow-up questions. (Authors)

From this study it might be concluded that the development of conservation of quantity cannot be explained by maturation. (Author)
