Compares the Genevan and Cattell-Horn theories of intelligence and describes both similarities and differences. Describes a study investigating the relation of the Piagetian operative level to the child's ability to use crystallized solution procedures (aids) in making elementary numerical comparisons. (HOD)

One hundred students (ages 6-8) described similarities and differences among exemplars of different categories, identified the categories, and named the exemplars. Large performance differences were found between normally achieving and mildly retarded groups and between mildly retarded and learning-disabled groups, with small performance…

The level of meaning (membership, partial association, or generalization) that English-speaking (N=1635) and Hindi-speaking students (N=823) preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter" was measured for each concept. Results and implications for science instruction are…

The purpose of this study was to determine how children at different ages understand the concept of temperature, examining particularly the logicomathematical aspects of the concept. In doing so, three developmental approaches were compared: (1) Piaget's structuralist approach; (2) Siegler's rule assessment approach; and (3) Anderson and…

Describes three experiments that tested autistic children's nonverbal and verbal categorization abilities. Concludes that autistic children do not suffer a specific cognitive deficit in ability to categorize and form abstract concepts. (HOD)

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)

The difficulties that younger students experience in understanding concepts related to the use of variables in computer programming are examined through descriptions of two studies: (1) detailed case studies of six highly intelligent children--three fourth graders and three sixth graders--who learned to program in BASIC during 60 hours of…

Students in grades four, five, and six who represented three classifications of ability were compared for their conceptualizations, attributions, and attitudes about school grading practices. Intellectually gifted, learning disabled, and normally achieving students were assessed. Significant differences were found among the three groups,…

Examines how an economic concept changed when 68 third-grade Italian children underwent different kinds of experiences simulated by means of tutorial and critical training. (HOD)

Five experiments examined the developmental relation between attention to target and context information and target memory among second and fifth graders and college adults. Results show that when the context is meaningfully related to target information, adults are less selective than children and are more likely to attend to context information.…

This study of college students in business administration classes compares attitudes toward office computer use of students with typing or word processing skills to those of students without those skills. Results show typing and/or word processing skills were associated with greater degree of conceptual understanding of future office computer use.…

Employing a new procedure for measuring peer concepts, this study investigated the development of differentiation and accuracy of children's concepts of their peers' attributes. Subjects, 18 second-graders, 23 fourth-graders, and 18 sixth-graders, were asked to rate characteristics of their peers in mathematics, athletics (running), and in two…

Two studies were conducted to compare the advance organizer and concept elaboration models of instruction with a task analysis approach. It was hypothesized that the concept elaboration group would achieve significantly higher than either the advance organizer group or the task analysis group on concept learning and principle learning. A pilot…

Presents a continuation of previous research on a general development process consisting of successive levels in conceptualization. Explores how young children conceptualize the writing system. Considers both social background and preschool system of education. Concludes that teaching activities used in French nursery schools are less effective…
