The development and use of educational software for children with severe learning problems are described. The software deals with common conceptual, communicative, and problem-solving problems in this population. It is argued that appropriately structured computer-mediated interaction can result in development and expression of cognitive skills…

Discusses the question of aptitude from within an information-processing perspective, examines how aptitude is conceptualized in this framework, and discusses one possible component of L2 aptitude: working memory. (56 references) (Author/CK)

Annotates 16 World Wide Web (WWW) sites dealing with math and science education matters covered in feature articles for this journal issue. Topics include math fairs, classroom restructuring, and hands-on science. (JW)

Reviews four books: (1) "A Dynamic Systems Approach to Development: Applications" (Linda B. Smith and Esther Thelen, Eds.); (2) "The Psychology of Gender" (Anne E. Beall and Robert J. Sternberg, Eds.); (3) "Children's Understanding: The Development of Mental Models" (Graeme S. Halford); and (4) "Adolescent Storm…

A study documented 10 college students' understanding of the limit concept and the factors affecting changes in that understanding. Encouragement by the researchers for the students to change their common informal models of limit to more formal conceptions were met with extreme resistance. (Author/JJK)

Discusses the rationale and a method for the instructional use of graphing calculators as an intermediary step between the intuitive notion of the concept of a limit and its formal epsilon-delta definition. (JJK)

Analysis of data on children's ideas about seeing and light is reported. Analysis is theoretically informed by Piagetian stage theory of genetic epistemology. Data produced by other researchers have been recoded to enable quantitative comparisons to be made with the survey data reported by Shayer and Adey (1981). Patterns in the data exposed by…

An interactive computer/videodisc learning approach to the conventional laboratory approach for learning biology concepts and science process skills were compared. The two approaches appear equivalent when evaluated by traditional learning outcomes, but the interactive videodisc strategy was significantly more time efficient than a traditional…

Presents research findings related to students' intuitive ideas about the concepts of chance to inform teachers how students form their concepts of probability and statistics. Discusses adolescents' conceptions of uncertainty, judgmental heuristics in making estimates of event likelihood, the conjunction fallacy, the outcome approach, attempts to…

Proposes the use of conceptual discrepancies to stimulate student inquiry into scientific concepts. Provides a list of 20 examples of conceptual discrepancies from the biological sciences that have encouraged self-regulation in biology students. (Contains 12 references.) (MDH)

Suggests that the teaching/learning/research process should be rethought of as a collaborative social learning for constructivism to be meaningful in science education. Includes perspectives on George Kelly's personal construct psychology and Glaserfeld's radical constructivism. (AIM)

A total of 270 children from 3 ethnic groups were tested for understanding of concepts of heating and cooling. A strong horizontal decalage effect was seen, with children of all ethnic groups using more sophisticated explanations at earlier ages for heating than cooling. Implications for developmental theory are discussed. (SLD)

A study examined whether exemplar-specific or prototype representations were primarily used by 28 children (ages 10-12) with mild mental retardation in a categorization task consisting of two groups of make-believe animals whose features were ill-defined. Results indicated the children were able to acquire and use both types of representations.…

Contrary to assumptions about aversive effects of competition on achievement motivation, in this study young people saw academic contests as fair. When participants completed structural interviews on fair ways to organize science contests and on differentiation of skill and luck, age-related trends in their conceptions of procedural justice were…

Examined the development of children's conceptual understanding of attention by focusing on their awareness of various subtypes of attention. Found three changes with increasing age: (1) less emphasis placed on surface features of scenarios used in similarity judgments; (2) more attentional subtypes identified; and (3) more emphasis placed on the…
