A study explored the relation between Piagetian conservation tasks, IQ scores, and reading test scores. A series of 16 items involving conservation tasks for area, length, weight, and volume were presented to 516 students in grades four through nine. The scores on these conservation items were correlated with students' scores on achievement and IQ…

This paper examines the concept of decalage from two cognitive-change positions (structures of logical thought and attentional and verbal mediators) and proposes an alternative explanation for decalage from a perceptual-change point of view. The term decalage is used to summarize the relation between differences in performance of various age…

The purpose of this study was to test the effect of several cognitive development capacities on first-grade children's ability to learn basic concepts and skills of linear measurement. The cognitive capacities of interest were logical reasoning ability and information processing capacity. The hypotheses predicted that children who had not yet…

This report summarizes the work completed and outlines the plans for future research of an ongoing research program of the department of psychology at Wayne State University. The program is concerned with the identification and description of cross-cultural and developmental differences in the conceptualization and linguistic expression of…

The question of developmental synchrony within the concrete operations period described in Piagetian literature was investigated. The idea of synchrony has been challenged by Brainerd's initial groupement research, which indicated a two-dimensional structure, corresponding to class operations and relational operations. A review of the literature…

This study is one of a series which attempts to arrive at generalizations about the learning of mathematics and the use of its terminology in the context of mathematical structure by young children. The first half of the document describes an experimental training program designed to integrate mathematical concepts of metric space, arc length, and…

This paper presents a study using a neo-Piagetian theory to analyze the micro-structure underlying Piaget's "control of variables" scheme. Data are presented which support the conclusion that young children are capable of acquiring and utilizing this scheme before they acquire Conservation of Weight, that is, providing (1) that the…

The effects of conservation activities on children's acquisition of Piaget's conservation concepts were investigated. One hundred and twenty-eight seven-to nine-year-old children in four classrooms were given pre- and post-evaluation measures of conservation ability. The experimental group completed a set of 42 self-directed conservation…

Seven investigations of modeling as a teaching technique are reviewed in this paper. Children in the individual projects varied, but included Anglo-Americans and Mexican-Americans from the kindergarten, and second, third and fifth grades. Modeling effects were examined in the following areas of teaching concern: (1) concept formation, transfer and…

This bibliography has been compiled to alert educators to documents about concept development in young children, particularly the development of number concepts found in the ERIC microfiche collection and in journal literature. Abstracts of selected documents were taken from "Research in Education (RIE)" and journal article citations from the…

This publication lists the consumer services of every Federal agency or bureau that is either directly of indirectly concerned with consumer issues. Services covered include agricultural research service, consumer and marketing service, extension service, food and nutrition service, rural development and conservation, farm credit, environmental…

To compare the adolescent's mode of thinking on one specific measure of cognition, conservation of volume, with his mode of thinking on a task simulating a familiar real-life situation, a study was made using 162 students (76 males and 86 females, 13.4 to 17.7 years of age, grades 7,8,9,10,12). The students, grouped according to age into four…

The efficacy of small group instructional activities dealing with transitive inference, conservation, and class inclusion of length was investigated in a sample of kindergarten (N=44) and first grade (N=45) children (mean ages of 5 years, 7 months and 6 years, 7 months respectively). The two instructional sessions (10 to 15 minutes each) employed…

Proposes that teachers should examine the elements of mathematical understandings that precede conservation and one-to-one correspondence and tailor classroom instruction to benefit both conserving and nonconserving students. (PK)

Designed to determine whether computer-assisted instruction could enhance performance on Piagetian classification and conservation tasks, this study divided 44 preschool children into an experimental group, which was exposed to computer lessons, and a control group. Both age and computer exposure were found to be significant variables. (LRW)
