Abstracts of most of the papers presented at the 57th Annual Meeting of the National Association for Research in Science Teaching (NARST) have been collected in this publication. Papers focus on such areas as cognitive structure, development of scientific literacy in secondary schools, science teaching as a career, improving science teaching,…

The five chapters of this book discuss children's development and learning. Chapter 1, by Barbara Z. Presseisen, raises fundamental questions about schooling and learning. Chapter 2, by Robert J. Sternberg, presents a theory of intellectual styles and discusses its relevance for education. The theory concerns the ways in which people use their…

This fourth yearbook on research on mathematics teaching in Finland contains five articles, four in English and the fifth in German. "Mathematics as a Cognitive Science" (C. Letteri) examines cognitive aspects related to teaching and learning mathematics, with the focus on the different levels of comprehension and an analysis of basic…

This document contains plans for 31 lessons intended to develop thinking skills using library media center materials primarily in the areas of language arts and social studies. Designed for various grade levels in the K-12 range, each of the lessons contains the following components: (1) behavioral and thinking skills objectives; (2) desired…

This paper is concerned with the role of speech in the development of control of cognitive processes, with particular attention paid to the nature of bilingualism. It is stated that exposure to a second language provides a way of overcoming the encapsulation of the mind that develops when an individual is exposed to only one language. In order to…

Research on the development of ability to control variables during adolescence is reviewed. The first section discusses studies by Piaget and his collaborators, replications of Piaget's studies, and related studies by other investigators. Factors which influence performance on controlling variables tasks are delineated; the existence of Piaget's…

This article hypothesizes that language repetition of young children (in the sense used by Kobashigawa and Snow) does not help language acquisition. The evidence comes from the results of a prior study in which no indication was found that mothers who repeat themselves a great deal have children who acquire language more quickly. However,…

The "cognitive clarity theory of reading" represents a resolution of the controversies about the relation between speech, writing, and reading. The work of M.A.K. Halliday suggests that learning to read and write is a natural extension of the "mathetic" speech functions, which consist of speech related to children's attempts to understand…

THE MAJOR PURPOSE OF THIS RESEARCH WAS TO DETERMINE WHETHER TRAINING IN SPECIFIC COGNITIVE PROCESSES IS EFFECTIVE IN INCREASING THE COGNITIVE FUNCTIONING OF RETARDED CHILDREN. IN PHASE I OF THE PROJECT, 51 EDUCABLE RETARDED AND 18 NORMAL SUBJECTS RECEIVED A 20-DAY PROGRAM IN SIMILARITIES-DIFFERENCES CONCEPT FORMATION AND WERE COMPARED WITH 42…

This study was designed to investigate the relationship between the level of conservation of displaced volume and the degree to which sixth-grade children learn the volume algorithm of a cuboid, namely, volume equals weight times length times height. The problem chosen is based on an apparent discrepancy between the present school programs and…

SPEAKING AN ORAL LANGUAGE AND SPEAKING A WRITTEN LANGUAGE INVOLVE DIFFERENT PATTERNS OF LANGUAGE USE WHICH ARE IN TURN RELATED TO DIFFERENT EDUCATIONAL METHODS AND DIFFERENT COURSES OF COGNITIVE DEVELOPMENT. BECAUSE ORAL SPEECH RELIES ON CONTEXT FOR COMMUNICATION, A COMMON CONTEXT AND POINT OF VIEW IS ASSUMED BY THE SPEAKER TO EXIST BETWEEN THE…

To test the hypothesis that if given a curriculum designed to develop cognitive functioning and taught by strategies designed to develop cognitive skills, students would then master more sophisticated symbolic thought earlier and more systematically than could be expected if this development had been left to the accidents of experience or if…

This paper reports the findings of an investigation into the development of the use and understanding of locative and temporal prepositions in 94 children aged from 18 months to 8 years. The research was carried out as part of the Project "Language Development in Pre-School Children," directed by Gordon Wells, at the University of…

This bibliography, made up of approximately 350 entries concerned with many aspects of problem solving and concept formation in young children, has been designed for use by people primarily involved in experimental research in these areas of child development. Entries include experimental journal articles, conference papers, unpublished research…

Sex differences in cerebral organization and functioning, and the apparent superiority of males in spatial ability are examined in this paper. Attention is given to several kinds of cognitive and perceptual tasks in which sex differences in spatial ability have been shown to exist; among these are tasks involving: (1) recall and detection of…
