TWO SUMMER 1965 HEAD START PROGRAMS, ONE IN BRONX RIVER AND ONE IN EAST TREMONT, NEW YORK, WERE SELECTED IN ORDER TO MEASURE THE CHANGES PRODUCED IN THE 36 PARTICIPANTS AS A RESULT OF THEIR HEAD START EXPERIENCE. AREAS MEASURED WERE (1) COGNITIVE FUNCTIONING, (2) PATTERNS OF PLAY AND USE OF PLAY MATERIALS, AND (3) CHILDREN'S FANTASIES ABOUT THEIR…

A STUDY WAS CONDUCTED TO FIND OUT WHAT MENTAL PROCESSES ARE INVOLVED IN THE DEVELOPMENT OF THE CONCEPT OF CONSERVATION OF CONTINUOUS QUANTITY, AT WHAT AGES THESE PROCESSES ARE DEVELOPED IN CHILDREN, AND WHETHER THEY ARE ADEQUATELY EXPLAINED BY PIAGET'S THEORY. ONE HUNDRED 5.75 TO 7-YEAR-OLDS WITH A MEAN I.Q. OF 105 WERE PRETESTED AND CLASSIFIED AS…

THIS BIBLIOGRAPHY LISTS MATERIAL ON VARIOUS ASPECTS OF COGNITION. APPROXIMATELY 120 UNANNOTATED REFERENCES ARE PROVIDED TO DOCUMENTS DATING MAINLY FROM 1960 TO 1966. LISTINGS ARE PRIMARILY JOURNAL ARTICLES, CONFERENCE PAPERS, AND RESEARCH REPORTS. SOME OF THE SUBJECT AREAS INCLUDED ARE (1) COGNITIVE DEVELOPMENT, (2) PIAGET'S THEORIES, (3)…

First-, third- and fifth-grade children participated in a study of information seeking, using a "Twenty Questions" procedure with a hierarchical array of pictures. Economy of inquiry increased with grade but was unaffected by practice, replaying a game, or observing a model. Age differences in types of questions reflected differences in…

The focus of this paper is on the use of frames in achieving understanding of learning and problem solving in school mathematics. The paper seeks to illustrate the use that has been made of frames and frame-like conceptions and to add to the case for the usefulness of such conceptions. Results reported are: (1) those related to more sequential…

This study was created primarily to explore new techniques and to generate fruitful new hypotheses and procedures for the (1) description of variations in expressed curiosity and constructive exploration among disadvantaged preschool children and (2) assessment of the relationship between such curiosity and exploration and other aspects of the…

This study is concerned with determining the relative effectiveness of a static and dynamic theoretical model in teaching elementary school students to use the particle idea of matter when explaining certain physical phenomena. A clinical method of personal individual interview-testing, teaching, and retesting of a random sample population from…

Two studies attempted to determine: (1) at what age children understand and apply the principle of equity; and (2) whether theory based instruction is effective in helping young children understand the principle of equity. Further, do children exposed to such instruction perform better on a behavioral test than children not exposed to such…

This paper presents a study of the relationship between compensation and conservation in 80 children, ages 5-6. Findings are compared to those of an earlier experiment which was designed to determine whether or not prior knowledge of the compensation rule increases kindergarten children's susceptibility to conservation training experiences. It is…

This paper briefly reviews the literature concerning the Paiget-Burner debate over the roles of identify and reversibility rules in conservation acquisition, and describes an experiment designed to determine whether one group of rules is more closely related to conservation than the other. A group of children, aged 4-6 years, received tests of…

Fifteen research reports related to mathematics education are abstracted and analyzed. The reports abstracted were selected from nine educational journals including several published outside the United States, and deal with a wide variety of topics. Three articles deal with concept formation, three with task analysis or instructional sequencing,…

Many preschool children with developmental delays in cognition and language are in the preoperational stage as defined by Jean Piaget's theory of cognitive development. The preoperational stage is divided into the preconceptual and the intuitive phases. During the preconceptual phase, the preschooler is unable to form true concepts and often…

This paper attempts to clarify some of the issues raised in the author's earlier paper, "A Theoretical Perspective on the Relationship between Bilingualism and Thought" (Working Papers on Bilingualism, No. 1), as a response to Gerald Neufeld's critique, which appeared in No. 2 of the same series. The present paper argues that Neufeld mistakenly…

This book is a collection of the papers presented at the fifth International Interdisciplinary Conference on Piagetian Theory and the Helping Professions, held at the University of Southern California on January 24, 1975. The conference was sponsored by University Affiliated Program at Childrens Hospital of Los Angeles; 44 papers are included.…

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…
