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…

The article describes creative ways to interest children in mathematics. (CD)

Supports the hypothesis that a student must engage a subject in a manner appropriate to his or her present stage of development if he or she is to advance to the next stage of development. Advocates the practice of having introductory physics students observe physical phenomena while they are manipulating equipment in order to foster cognitive…

Metaphors of similarity and proportionality, together with a pictorial form of similarity metaphors, proverbs, and several Piaget-type cognitive tasks, were given to 50 boys aged 5 through 13 years. Results indicated that metaphor comprehension is a type of classificatory behavior, the development of which is related to maturing cognitive…

Explored the relationship between knowing how to think and teaching students to think. The findings indicated that development of pupil's intellectual capacities depend on an adequate assimilation of general methods of thinking and that psychology, logic, and pedagogy can today provide the teacher with the technical resources necessary to make…
