The development of children's causal knowledge is investigated by analyzing changes in the content and form of the explanations they generate across the age span of three to nine years. The balance of incremental versus fundamental change and the forms each takes in children coming to understand the working of gears are examined. Three phases of…

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…

Discussed are the developments in neural networks technology that promise to make computers a great deal smarter. The brain is described, and its workings are compared to that of a computer. Computer programs that allow the construction of a simulated neural network are discussed and evaluated. (KR)

Studied the relationship of joint mother-child planning before and during tasks, and the ability of four and eight year olds to plan on their own. Found that older children planned more effectively, especially during tasks, and that mothers of younger children concerned themselves with task procedures rather than strategy. (MDM)

Examined the ability of children from 6 to 12 years of age to draw human figures and to reconstruct the drawing abilities they possessed at earlier ages. Found that diachronic thinking, or the ability to understand a present situation as a stage in an evolving process, developed with age. (MDM)

Examined the development of sex typing among 558 children aged 5-12 years. Several measures gathered information on sex typing, children's cognitive maturity, and children's exposure to sex-typed models at home. Found that children's knowledge of stereotypes, flexibility, and sex-typed personal preferences increased with age. Concludes that…

Compared the collaborative patterns of seven- and five-year-old expert planners working with five-year-old novice planners on tasks requiring reverse sequencing strategies. Results suggest that cognitive gains are achieved when children collaborate with peers more expert than themselves in problem-solving activities. (MM)

Presents nine properties of a mathematics lesson to help preservice and inservice mathematics teachers become proficient lesson planners. Illustrates how these properties can fit into a cognitive developmental framework to improve lesson planning. (21 references) (MDH)

Reviews three books: (1) "Contemporary Issues in the Early Years: Working Collaboratively for Children" (Gillian Pugh, editor); (2) "Social Interaction and the Development of Language and Cognition," (Alison F. Garton); and (3) "Child and Nature," (World Organization for Early Childhood Education). (AC)

Most research on American and British preschool programs demonstrates that early learning experiences have an immediate positive impact on children's cognitive and social development. Because of this, there is a strong case for investment in high quality early learning on economic as well as social grounds. (MDM)

Reports on study of 80 elementary students in grades 3-6 to determine whether tempo perception and performance abilities increased with grade level and musical training. Finds that student performance and perceptions did increase with grade level and training. Concludes that modern technology has made research into tempo perception more precise…

Adding plastic gutters to the nursery school's sand area began as a science curriculum enhancement and evolved into a whole curriculum that stimulated cognitive exploration, cooperative dramatic play, language enhancement, and general fun. The children manipulated the gutters and materials such as sand, water, buckets, and tennis balls in a…

Provides brief overviews of the four articles in this issue. Articles concern (1) social influences on kindergartners' journal writing; (2) stress behaviors of kindergartners while taking standardized tests; (3) preschool teachers' attitudes about cognitive development, educational objectives, and curriculum practices; and (4) preschool teachers'…

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…

Two studies examined children's understanding of the origins, behaviors, and properties of objects. Children (1) were sensitive to the distinction between natural things and artifacts; (2) identified specific kinds of natural cause; and (3) understood the link between internal parts and self-generated activity.
