How can children's natural perceptuo-motor skills be harnessed for teaching and learning mathematical structure? We address this question in the case of the integers. Existing research suggests that adult mental representations of integers recruit perceptuo-motor functionalities involving symmetry. Building on these findings, we designed a…

Class-inclusion in first grade children was studied by using part-whole comparisons of families of stimuli (e.g., dogs). Results indicated that it was easier to make part-whole comparisons for the family relation than for the class-inclusion relation. (ST)

Reports identical effects of verbal labels and perceptual cues in children's concept attainment. (ST)

Reports two studies. The first study compared adults and children (aged four, six, and eight) on ability to sort paintings according to artist, a conceptual task that can reveal cognitive organization. The second study compared three groups of eight- to nine-year-olds using slightly different procedures. The results showed strong developmental…

Children's use of the middle concept was assessed in two developmental studies. Experiment 1, with kindergarten through fifth-grade students, showed marked improvement in the mastery of the middle concept across elementary grades. In Experiment 2, discrimination pretraining with two nonoverlapping stimulus sets transferred to the novel test…

The major objective of this study was to investigate the relationship between the perceptual preferences of elementary school children and their performance on pictorial model-based tests of selected science concepts. Perceptual preferences for size and shape did not significantly influence performance. Preference for color did appear to be…

Two major trends in the development of natural language concepts were found in the present study: (1) there was a clear indication that such concepts exist in a relatively fragmented form in young children; (2) young children showed a strong dependence on perceptual attributes in their definitions of concepts.

This paper describes two experiments in which children in grades 1, 3, and 5 were given three kinds of spatial perspective-taking problems to solve as quickly as they could: (1) C problems, solvable only by computation (that is, noting which features of a particular object array were closest to another observer in order to estimate how the array…

Describes two experiments that investigated the effects of two thematic retrieval cues on the types of information recalled from short stories by elementary school children and adults. Shows adults and fourth graders, but not younger children, spontaneously generated thematic retrieval plans which enabled them to remember information from both…

Compares kindergartners' and third and sixth graders' understanding of an illusion reported by the philosopher John Locke, in which two hands simultaneously experience two different temperatures from a container of water at one temperature. (HOD)

In 1964 World Book wanted to be able to say that more than 1,000 maps being made for the encyclopedia were designed to be appropriate and useful for children between the ages of nine and fourteen. However, there was virtually no research on which such a program could be based. This paper briefly reviews research projects in this area started in…

This study examines the relationship between development of a child's ability to coordinate perspective and his ability to conceptualize spatial relations on a map. One hundred and four school children from inner city, urban fringe, and suburban schools, grades K-6, were administered a Test of Coordination of Perspectives and a Test of Map…

Egocentrism was investigated as an influencing factor in the development of the perceptual abilities needed to understand and interpret topographic maps. Attainment of an adequate concept of space, and the ability to accurately perceive spatial relationships (perspectives) are considered fundamental. Piaget and Inhelder identified three stages of…

The University of Victoria and the Canadian Department of Indian Affairs sponsored a 4-week prekindergarten, preschool, and orientation program for Indian children living on 4 reserves in the southern region of Vancouver Island. The 3 groups of children served were 4- and 5-year-olds (prekindergarten), 5- and 6-year-olds (preschool), and 7-…
