Nineteen beginning preservice science teachers were randomly assigned to one of the following treatments given in the first two weeks of the semester: a) training in interaction analysis (a modification of Hall's instrument for the analysis of science teaching; b) training in conducting and interpreting Piaget-type interviews; and c) a control…

The instructional models included in this report have been developed as an attempt to combine relevant factual and conceptual knowledge with a pre-planned teacher effort to correlate these cognitive learnings with specific attitude development on the affective level. Each of the four models connects specific concepts, skills, and attitudes…

The study attempted to trace the relationship between facility with cardinal-ordinal aspects of number; attention to dimensions of number, length, and density; and the presence and absence of number conservation. On the basis of performances on the standard test for number conservation, 25 nonconserving kindergarteners, 34 conserving…

A proposed study of the differences in the way children perceive, approach, and behave in problem-solving situations is described. The behavioral measure to be used is "glancing," which has been related to outerdirectedness. Children will be given two sets of two puzzles to put together. On the basis of the number of glances and the situation in…

Based on a state requirement that all elementary and secondary schools provide instruction in the wise use of natural resources and protection of the environment, the California State Department of Education has developed this guide to assist local educational agencies in translating legislative mandates into action. It offers a structure and…

The development of the concept of seriation was studied for 415 children, ranging in age from 3 to 9 years. The subjects were required to learn to identify the larger or smaller object in a two stimulus series, the smallest or middle-sized object in a three stimulus series, and the largest or next to the smallest in a four stimulus series. The end…

The smiles and laughter of an infant form the beginning of the developmental process of interpersonal interaction and socialization. The earliest smiles are automatic expressions of internal states, but soon infants' smiles are communications of pleasure. The developmental changes in smiling and laughing in early infancy reflect the rapidity with…

Piagetian conservation tasks in relation to standard intelligence tests with mildly mentally retarded students from different ethnic groups were investigated. Seventy-five boys between the ages of 10 and 15, who scored between 65 and 80 on the WISC, were studied. Elkind's procedures for conservation of substance, weight, and volume were used.…

Reading research in which different methods or materials have been compared has proven inconclusive. This paper is restricted to beginning reading, defined as the acquisition of letter-sound decoding ability, and raises the question: what skills are required by current tests? Available reading readiness and achievement tests consist of batteries…

Reported were over 20 related studies that were intended as attempts to discover the psychological implications of deafness, with an emphasis on the perceptual-cognitive manifestations. The report was divided into three sections: the first reported the results of many studies investigating mainly the relationship between language and perception…

The differential visual responses of 20 Down's Syndrome and 20 normal infants (CA 8 months) to 13 pairs of visual targets were compared. Although DS subjects generally looked longer at the stimuli than normal subjects, they showed a response differential in only 3 stimulus pairs compared to 11 for the normals. Six of the stimulus pairs elicited…

Person perception is used in this study to refer to the behavioral domain which is also called interpersonal or social perception. This domain typically consists of judgments of other persons' actions, expressions, or intentions. Three groups of 10 children differing on IQ and CA comprised the subject population. One group was gifted, one average,…

STRUCTURAL (NONCONTENT) DIMENSIONS OF CHILDREN'S POLITICAL ATTITUDES AND THEIR DEVELOPMENT WERE INVESTIGATED USING NEW METHODS DERIVED FROM SELF-REPORT DATA. THE CONSTRUCT, "ATTITUDE-CONCEPT SYSTEM," WAS INTRODUCED TO DESIGNATE EVALUATIONS OF AN ATTITUDE OBJECT AND BELIEFS ASSOCIATED WITH THIS EVALUATION. THE FIVE STRUCTURAL DIMENSIONS…

Samples of 98 fourth graders and 111 sixth graders participated in a study of the relationships between operational thinking and reading comprehension of texts involving operational structures. Tests of operational thinking, reading comprehension, IQ, and vocabulary were administered in class groups. Results from correlational and factor analyses…

This study was designed to: (1) investigate differential responding to stimuli that differ along a continuum of degree of discrepancy from a familiarized standard; and (2) attempt to determine if infants will show response decrement and recovery to conceptual categories. Fifty-five infants at two age levels (10 and 16 weeks) were familiarized with…
