Describes a study that investigated the relationship and development of fifth-grade students' conceptual ecologies of heat. Contends that relying on a single mode of assessing students' learning can lead to a restricted view of what they truly know. (WRM)

Two experiments examined preschoolers' and adults' relative reliance on visual and verbal information in identification of animals and machines. Findings include both children and adults can use either visual or verbal cues in categorization, and a stricter definition is used in identifying animals. Results suggest that a perceptual to conceptual…

Presents a study in which the conversations of primary school groups were collected in a botanical garden and analyzed for content. The data were examined for the effects of the presence or absence of an adult in the group, age, and the sex of the pupils. (Contains 27 references.) (Author/DDR)

Summarizes findings on infants' capacity for object segregation. Maintains that infants can use featural and experiential information for segregation and individuation purposes long before 12 months of age. Disputes the claim that formation of object categories awaits early word learning, but acknowledges that language may play a key role in…

The development of cognitive representation is the main theme of three classic theories (Piaget, Bruner, Vygotsky) on how children learn concepts. Piaget considered structural change as a necessary condition for development; Bruner emphasized both internal and external function and the structural changes brought about by function; and Vygotsky…

Schemas are cognitive structures or forms of thought, like pieces of ideas or concepts. Patterns in children's behavior, or in their drawings and paintings, indicate common themes or threads (schemas) running through them. The action research study described in this report examined the effects on children's learning of intervening in their…

Three different theory of mind tasks were conducted with 4- to 8-year-old Quechua peasant children in the Peruvian Andes. The study investigated the ways in which children in preliterate cultures think and the possibility that they think differently than children in literate cultures. The tasks included: (1) a false-belief task, which tested the…

The first of two parts in this document is a student workbook which is designed to teach students how to construct a concept map, i.e., a graphic arrangement of the key concepts in a body of subject matter with connecting lines labelled to show valid and meaningful relationships between the chosen concepts. The workbook provides a discussion of…

Designed to focus attention on the design process in such computer science activities as information systems design, database design, and expert systems design, this paper examines three main phases of the design process: understanding the context of the problem, identifying the problem, and finding a solution. The processes that these phases…

Perspectives on the need for consistency in considering the promotion of conceptual change in science students and teachers (and in some circumstances, researchers) are presented in this paper. The parallels between the consequences of this consistency and the literature on educational change are also highlighted. A particular focus is directed to…

A constructivist analysis of the concepts of communication and environment may go against the traditional ideas of realists. Both concepts are treated as subjective constructs of a cognizing agent. It is held that the basis of the constructivist theory of knowing as the idea that knowledge is a mapping of ways of acting and thinking and the result…

After a review of the literature on cognitive "cause maps" in organizational decision-making, this study describes a midwestern elementary school from the perspective of individual sensemaking, captured through individual cognitive maps of cause-effect relationships. Data were collected with an adaptation of Bougon's (1983) Self-Q…

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

Discusses some of the ways that some scientific concepts evolve and are perpetuated, even if they are not completely accurate. Uses the example of groundwater, citing numerous ways that various people understand it and, in many cases, form misconceptions. (TW)

Presents an ethnographic study of whether a heterogeneous group of Sotho people in Southern Africa continues to subscribe to a particular cultural metaphor concerning heat, even though the group is no longer strictly traditional in its way of life. Considers implications of the metaphor's persistence for the learning of orthodox scientific…
