Increase in sex-role knowledge represents an early stage of the development of sex role stereotypes in children, which is followed by a decrease in the extent of sex-role discrimination. This process is related to the acquisition of classificatory skills. Groups of children aged 4-10 years were tested for their sex role stereotypes and…

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

The study examined the effectiveness of enhancing perceptual differentiation in the training of four developmentally delayed preschool children who were so low-functioning that they did not demonstrate oddity responding (ability to choose one distinct stimulus from a group of identical stimuli). Instead of the Arabic numerals used in the original…

The terms and concepts children used to explain their beliefs about computers before and after classroom exposure to microcomputers were studied to identify misconceptions about computers that could interfere with computer-based learning. Children in each of two classrooms at the Bank Street School for Children were interviewed individually on…

The purpose of this article is to outline some of the characteristics of children's notions of physical causality and to relate this to how one might expect the typical five-year-old, eight-year-old, and twelve-year-old to approach a problem in science. (Author)

Presents a study which assessed preschool children's understanding of "front,""back," and "side" through a variety of tasks. A developmental sequence is defined. (ED)

Children aged 3, 6, 9 and 12 years were asked to name and sort 25 different drinking vessels. Results showed three stages: (1) they ove rextend the term "cup"; (2) they focus only on certain perceptual properties; (3) they show growing awareness of functional properties and hence the vagueness of the boundary.

The formal operations skills and problem solving performance of 60 gifted girls (grades 4 through 6) were investigated. Ss were given Piagetian tasks which involved conservation of mass and weight, use of proportion, oscillation of the pendulum, and projection of shadows. Among findings were the following: (1) no relationship between IQ and either…

Children three through six years of age were asked to imitate actions depicted in photographs to determine whether they could interpret information of action in photographs. Twenty children at each of four age levels, 3, 4, 5, and 6 years, were asked to imitate two photos, each showing a young child performing a physical action. Following this…

This paper suggests that language study focus its attention more on the pedagogical needs of educators by offering them a more comprehensive dialectical and unifying theory of language development that could then present the process as a holistic endeavor instead of as a set of separate linguistic acquisitions. Specifically, it suggests the use…

This document, published in India by the Regional College of Education, deals with 13 subjects: the tough context (thinking), definitions of concept, functions of concept, the process of concept formation, discriminant learning, mediation process, second signalling system, factors affecting concept formation, studies in concept formation, the…

This study was designed to test two alternate hypotheses regarding the meaning of increased lateral head movements in infants during experiments in which the mothers' voices were displaced from their faces. One interpretation is that the lateral looking responses of the infants are attributable to maturational effects on the infants' physiological…

This document reviews the use of mathematical models of learning for research in the learning of science concepts. Three mathematical models for the representation of concept learning are presented. (SL)
