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)

The development of tools for testing the abilities of students in "interpreting data" is discussed. A longitudinal and cross-sectional study of the responses of examinees and the application of SOLO Taxonomy for the design of structured questions to classify the level of performance of examinees were used to select indicative items. (KR)

Compared are the van Hiele levels of geometric thinking and the geometry curriculum recommended by the National Council of Teachers of Mathematics Curriculum and Evaluation Standards for School Mathematics. Activities which illustrate the various levels are provided by grade level with procedures. (CW)

Discussed is an alternative teaching strategy to uncover and assess a common misconception in the life sciences and to articulate its use in teaching a unit on angiosperm reproduction. The learning cycle is described, and a concept map on reproduction on angiosperms is included. (KR)

A battery of questionnaires administered to 121 male and female high school freshmen, college freshmen, and college seniors provided evidence that the greater role conflict experienced by females fosters earlier relativistic and/or dialectical reasoning and more differentiated role articulation regarding family and career issues. (DM)

Examines three approaches to fostering higher level thinking in students: (1) the stand-alone approach; (2) the embedding approach; and (3) the immersion approach. The first two approaches teach thinking skills separately from or in the context of subject matter content; the immersion approach assigns an active role to perception and downplays…

Argues for expanding the present discourse on developmental appropriateness on the grounds that this discourse assumes consensus about child development; is premised on a suspect notion of broad, universal stages; and ignores alternative perspectives on learning and development and the relationship between the two.
