The first part of this research study examines how elementary students discover and understand certain relationships in nature. The second part investigates how pupils operate with overlapping concepts. (Author/RM)

CONCEPT FORMATION--AS IT IS AFFECTED BY SUBJECTS (NORMAL AND RETARDED), PROBLEMS (SIMULTANEOUS, SUCCESSIVE, AND SIMILARITY-DIFFERENCE), RESPONSES (MANUAL AND VERBAL), REINFORCEMENT (100 PERCENT AND PARTIAL REINFORCEMENT), AND STIMULI--WAS INVESTIGATED. ELEVEN SEPARATE EXPERIMENTS ARE DESCRIBED. IT WAS FOUND THAT--(1) CONCEPT ATTAINMENT IS…

In a program to facilitate the emergence of number conservation in preschool children, 45 middle class children and 64 Head Start and Title I children were trained to deal with perceptual confusions so that they could utilize this understanding to disregard irrelevant changes, such as spatial rearrangement, and thereby become aware of conservation…

This paper is concerned with one aspect of intellectual functioning, logico-mathematical concepts, and with development of representational space in opportunity class children (those characterized mainly by cultural deprivation, intellectual retardation at the Educable Mentally Retarded-borderline levels, and specific learning disabilities) who…

Photographs and anecdotal narratives tell stories of concept and language learning by six deaf four-year-old children. Through the misfortune of deafness it was possible to study some matters of learning and communication which involve only the language of action. The author also makes observations about the principle of choice as it contributes…

The experimental CAI system which is being tested at Delft University of Technology is structured in a modular manner to account for high changeability. The concept formulated for this project was the outcome of research into technological, organizational, and educational developments in CAI, and the enumeration of the common aspects of the…

Based on the belief that structured preschool activities aid in the development of disadvantaged children, this study attempted (1) to evolve a tutorial program to accelerate spontaneous development in disadvantaged children and prevent cognitive and language deficits, and (2) to assess growth of the infant's cognitive and language development…

TO STUDY WHICH OF SEVERAL CONDITIONS PROMOTES EFFICIENT CONCEPT LEARNING, AN EXPERIMENT INVOLVING 2 CONDITIONS, METHOD OF PRESENTATION OF STIMULI AND RATIO OF POSITIVE TO NEGATIVE STIMULI, WAS ADMINISTERED TO 80 SECOND-GRADE CHILDREN. THE CHILDREN WERE DIVIDED INTO 8 TREATMENT GROUPS. THESE 8 GROUPS WERE FORMED BY VARYING THE 2 METHODS OF…

The inappropriateness of standard experimental research design, which can stifle innovations, is discussed in connection with the problems of designing practical techniques for evaluating a Title III curriculum development project. The project, involving 12 school districts and 2,500 students, teaches concept understanding, critical thinking, and…

This experiment was designed to study the value of oral response as opposed to nonoral response in learning by kindergarten children. Approximately 108 kindergarten children were used. About 80 of them were placed in the two experimental groups (that is, the oral and nonoral groups), and the others were placed in a control group. Phase I involved…

A project conducted several years ago to develop informal mathematical learning experiences at kindergarten level is compared with the results of the work-book type (formal) program being used at that time. It is hypothesized that kindergarten pupils who study mathematical concepts in a planned, sequential, systematic, but non-workbook (informal)…

Six approaches to community development are presented by several authors in this booklet. Chapter 1 presents an introduction to the community development concept. In chapter 2, L. J. Cary emphasizes three distinctive features of the community approach: (1) popular or broad-based participation, (2) community as an important concept, and (3) the…

The paper describes an experimental program for college freshmen which applies Piaget's theory of human development to students' academic and social experiences. The program, Accenting Development of Abstract Processes of Thought (ADAPT), was designed to facilitate movement of students from concrete operational thought patterns to more formal…

The original objective of the nursery school was that acting in cooperation with the home, it should develop children motorically, intellectually, emotionally, and socially. A comparison of objectives with effects reveals many to be non-existent. A 1966 study of nursery school effects on child development revealed the following breakdown: (1)…

Emphasizing the design of a data base management system for the experimental STITE (Scientific and Technical Information Transfer for Education) project, this progress report details the emerging features of this projected facility. Compiled by four STITE researchers, the report examines: science information communication, learning, dissemination,…
