This study examined the relative influence of observation, feedback in training seriation, and imitative motor activity in facilitating conceptual development. (CM)

The development of the concept of conservation was examined in 120 elementary school children divided into three groups: partially sighted, sighted, and sighted-blindfolded. (CM)

Describes nine consequences for children who are given the opportunity to work with art teachers. Some of these are that making images provides intrinsic satisfaction; children learn that the images they create can function as symbols; and children's power to conceptualize visual ideas and to use effective means of expressing them increases. (KC)

The ability of 47 EMR (educable mentally retarded) and 51 nonretarded children (ages 8 to 15) to maintain and generalize a sorting and retrieval strategy designed to facilitate recall and clustering was examined. Neither the far generalization data nor the near generalization data revealed any significant results. (Author)

The rules and concepts of basic moral reasoning can be taught without difficulty to quite young children; but educating them to prefer to use these rules is another matter. Kohlberg's stages are not likely to be stages of cognitive reasoning, but indication of the reasoning encouraged by the child's environment. (Author/SJL)

Argues the importance of teaching fractions and discusses examples of fundamental problems in students' conceptualization of common fractions and decimal fractions. (SS)

A study involving 65 children from 5.6 to 9.5 years of age suggested that the average child's ability to differentiate spoken words from other units of speech improves with age and that significant relationships exist between children's knowledge of spoken words and their reading achievement. (GT)

Reports three experiments to investigate differences in the semantic classification of pictures and words. The data suggest that visual short-term memory and semantic memory operate in semantic-decision tasks though these sources of information differ in characteristics, potential for activation, and level of abstraction. (PMJ)

This study is a longitudinal follow-up analysis of children's performances on a number of Piagetian concrete operations tasks dealing with conservation and transitive inference. Subjects were 102 children selected from kindergarten and grades 1, 3, and 4. (Author/MP)

The purpose of this study was to determine what effect exposure to linguistic input pertinent to kinship terms and kinship relations has on the acquisition of the meaning of such terms. The subjects were 84 German children living in families, and 84 orphans. (Author/CFM)

Differences in approaches to research into student learning are analyzed in terms of differences in the conception of six aspects of the research process. It is argued that underlying various strategies there is a variation in perspective, description, conceptualization, relations of categories, comprehension, and application of findings.…

A data analysis procedure for testing the hypothesis that one task is a developmental prerequisite for another task is illustrated. The procedure was applied to new data on the acquisition of conservation concepts to test the hypothesis that synthesis, visual-scanning skills, and memory capacity are prerequisites of conservation mastery. (JMB)

Two studies sought to determine the developmental relationship between the child's use of counting as a notational symbol system to extract, compare, and reproduce numerical information and the development of number conservation. Subjects were four- to six-year-old children in Study 1 and seven- to nine-year-old learning disabled children in Study…

A description is given of a teacher's technique for teaching mathematics to mixed-ability groups. Examples from two lessons are given. (MK)

This article describes a seventh-grade physical education class project that called for definitions of 21 terms such as human movement, dance, rhythm, time, space, etc. Individual projects included booklets, movies, photomontages, scrapbooks, and posters. (JMF)
