Discussed is the type of evidence children find to be convincing using either empirical or deductive methods to justify propositions which they consider to be true. Included are the problem, research design, and the conclusion. (KR)

Presents research on individuals' ability to perform Piaget's water-level task. At almost every age and for each sex, some subjects had high probability of success and some had low. Age-related improvement was not a result of children's increasing accuracy in task performance. Differences in performance between sexes were evident at all ages.…

This paper presents a theoretical framework for investigating the role of algorithms in mathematical thinking using a combined ontological-psychological outlook. The intent is to demonstrate that the processes of learning and of problem solving incorporate an elaborate interplay between operational and structural conceptualizations of the same…

Reviews the evidence for differences between the sexes in their experience of higher education. Describes and compares research using both quantitative and qualitative methods. Argues that a primary educational objective should be enhancing the academic integration of women in a supportive environment in which interpersonal understanding can be…

Describes the psychological analysis of the instruction of the concept of multiplication in the former Soviet Union. Presents a system of instructional situations in introducing multiplication and the main results of instruction for grade two. (MDH)

Presents four areas of advanced mathematical research (fuzzy set theory, subjective probability, search theory, and Voronoi diagrams) that are proposed for introduction into teacher education programs from an elementary, survey perspective without the intention of accomplishing formal mathematical research, thereby challenging teachers' beliefs…

Reports on the development and application of a series of computer programs which simulate the outcomes of students' perceptions regarding forces acting on objects at rest or in motion. This dissonance-based strategy for achieving conceptual change uses an arrow-based vector language to enable students to express their conceptual understanding.…

A 7-month longitudinal study of 20 2- and 3-year-old children shows that children at an early age already know that counting words each refer to a distinct numerosity, although they do not know to which numerosity. It takes children a long time to learn the latter. (SLD)

Discusses the differences between Piagetian and post-Piagetian conceptions of intellectual development and the implications of these differences for science education in early childhood. (GLR)

Discusses the evolution and current status of cognitive research in music. Identifies the field's five research branches: (1) sensation; (2) perception; (3) concept formation and memory; (4) affect or emotions; and (5) psychomotor activity. Recommends five changes for the future of cognitive musicology. (CFR)

Two studies of high ability students' communal notions about the purposes of school and the fairness of classroom practices suggest that the moral and intellectual development of high ability students would be best fostered by collaborative learning practices and by educational programs that encourage them to seek knowledge that will be of value…

Attention deficit disorder with hyperactivity (ADHD), which is conceptualized as a lack of behavioral inhibition or self-regulation, is reviewed. The article examines the relationship between ADHD and language delays/disorders, possible language and social-emotional cognitive underpinnings for pragmatic and metacognitive deficits in ADHD children,…

This article presents a rationale for emphasizing discovery instruction over guided instruction in teaching cane travel skills to people with severe visual impairments. Discovery instruction is seen to facilitate the use of intrinsic feedback in developing perceptual-cognitive skills as well as promoting problem solving, retention, and transfer of…

Reviews research on the development of academic skills in arithmetic and early reading, emphasizing the individual cognitive processes occurring during learning. Offers implications for the development of new methods of assessment that stress processes, rather than just products. Suggests that researchers in cognitive development and assessment…

Reviews the research on (1) developmental stages of play among young children; (2) solitary play as a separate continuum with its own developmental stages; and (3) benefits of solitary play on the child's whole development. (BB)
