This paper presents three research studies. The first study investigated the use of boys' and girls' play areas, each stocked with sex-type toys, by day care children with male, female, or mixed teacher teams. Examined were the sex of play areas users and the effect of sex of teacher team on the structure of play in each play area. The second…

During 1970, the Appalachian Regional Development Program completed its 5th year of operations. Authorized under the 1965 Appalachian Regional Development Act, the program tries to cooperatively promote Appalachia's future economic and social development through a phased series of public investments to improve education, health, transportation,…

The purpose of the study was to determine whether mathematical concepts could be learned and retained by disadvantaged preschool children when taught by an inexperienced teacher. College sophomores used printed lesson plans with no further instruction with 94 severely disadvantaged children attending either Headstart schools of Day Care Centers in…

This handbook, primarily for parents and teachers of preschool through third grade children, provides some insights into Piaget's theories about how children think and learn and presents ideas for using Piagetian-type activities and games in the home or classroom. (The handbook does not attempt to give a comprehensive analysis of Piaget's theory…

Discusses the need to consider students' pre-existing conceptual schemes when teaching chemistry. Reports on a study done in Spain which indicates that the existence of adolescents preconceptions about gases is important to consider when teaching the principles of conservation of substance, mass, and weight.

Relationships which exist between self-perception in science and cognitive development were explored under two quantitatively different teaching strategies: the use or nonuse of directions, praise, and rejection. A less directive teaching strategy appears to provide a more positive environment for developing an independent self-perception in…

A general model of conceptual change which is largely derived from current philosophy of science, but which can illuminate learning as well, is described. Some features of this model are illustrated by interviews with students studying special relativity in physics. Finally, some pedagogical implications are presented. (Author/PB)

Summarizes a study to widen the applicability of Piagetian theory-based conflict methodology from individual situations to entire classes. A Solomon four group design was used to study effects of conflict instruction on students' (N=127) ability to conserve volume of noncompressible matter and to apply that knowledge to gas volume. (Author/JN)

Six studies investigated the use of pictorial material in a group setting to measure the cognitive level of children (age 7 to 11) on eight Piagetian concepts. Children were low to middle socioeconomic status with 60 percent Spanish surnames. Factor analysis and clinical administration supported test validity. (Author/CTM)

Two tests of cognitive development, the Cartoon Conservation Scales, Levels I and II, were designed to measure Piagetian stage-related constructs for children of different age groups. The tests were factor analyzed within age levels and were also analyzed using scalogram and tabular methods to test sequential hypotheses. (Author/CTM)

Explores both the qualitative and quantitative dimensions of pupils' ideas related to conservation during state changes of water. Analysis of questionnaire data indicates that qualitative understanding precedes quantitative. Contains 18 references. (DDR)

Among children ranging in age from 5.5 to 7.5 years, there was no evidence that social conflict engineered in dyads composed of a conserver and a nonconserver stimulated cognitive change. It is concluded that the ineffectiveness of symmetrical social conflict is consistent with Piaget's conception of nonconservers. (RH)

Reports on the assessment of student thinking in the area of commitment to the laws of conservation of matter and energy during a study of conceptual change among introductory chemistry students. States four conditions upon which strategies for conceptual change are based. (RT)

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…

All too often educators establish a "pretest, skill, posttest" type of curriculum. While this approach has an educational value, it must be used within a developmental framework based on individual thinking and learning style. Thus, a thorough knowledge of cognitive development is necessary. A review of the body of knowledge concerning…
