Reviews research literature leading to design of a new LOGO environment, Geo-LOGO, tailored for elementary students' learning of geometry. Presents empirical data from the first field test of the Geo-LOGO environment, which generally support the efficacy of the software design. (Author/MKR)

This commentary on the article by Jones and Smith in this issue examines whether coherent conceptual cores exist in long-term memory; abstract propositions constitute conceptual cores; concepts in long-term memory control behavior; and the primary purpose of developing and using concepts is to taxonomize the environment.

Argues that, by not considering examples drawn from students' everyday lives, a teacher is detracting from science itself. A challenge is made to Conceptual Change Learning Model advocates and users to embrace the idea of conceptual fitting based upon context as well as conceptual change when considering how students learn. (ZWH)

Concept maps are used at the Cornell University (New York) college of veterinary medicine for curriculum planning, particularly development of problem-based cases for classroom use. The maps help prioritize concepts, refine objectives and details, articulate links between aspects of a case, and support overall course design. (MSE)

Discusses four general principles that help explain young children's preoperational thinking. Children tend to focus on one thing at a time; what they can see or experience; their own connections or explanations; and their own interpretations and representations. Suggests that teachers need to be good listeners and watch for clues to children's…

Examines children's understanding of the variation of sunlight and heat of the sun as experienced on the earth related to the positions of the earth and the sun in space, while using a pictorial computer simulation of the phenomenon. Suggests that, through the exploration of the program, children seemed to follow a correctly directed conceptual…

Presents teaching strategies that foster mathematical communication in young children, which validate their thinking, engage them in review of their thinking, and challenge them to extend their thinking. (MKR)

Describes the process of analysis for determining a teacher's conception of teaching science using interviews. Representations of a teacher's conception of teaching science include a grid for analyzing different themes in a teacher's conception, a brief summary of the themes, and a longer written interpretive summary. (23 references) (Author)

Scientific reasoning of four elementary age students with mild mental retardation was investigated using structured interviews during tasks involving properties of air and electricity. Discourse analysis was employed to describe students' preconceptions about the natural world and how those preconceptions might be influenced by empirical evidence.…

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…

Discusses the use of activities demonstrating connections between algebra and geometry, which helps students gain a conceptual understanding of important calculus ideas and gives a historical appreciation of how mathematics evolves. Uses distance, speed, and time problems as an example. (MKR)

Three studies examined children's ability to differentiate aggression and social withdrawal using attributional constructs. Found that even very young children understand the meaning of responsibility and are capable of using it to act as intuitive judges, weighing the evidence to make inferences about responsibility and then meting out judgments…

Discusses and contrasts varying definitions of empowerment from social work and feminist literature. Describes what is problematic in the definitions of empowerment practice with older women and suggests reasons for broadening the definition and concept of empowerment so that social welfare professionals can meet the needs of this growing…

Examined travel time in the family car as an opportunity for young children to use distant time referents in their talk with parents. Results supported preschoolers' tendency to talk predominantly about the here-and-now in most settings, but highlights factors that may contribute to children's increased use of decontextualized talk about past and…

Argues that current thinking about science teaching and conceptual change needs to be counterbalanced by contextual or cultural constructivist ideas. A collaborative view should include the sociological study of cultural milieus in which scientific ideas arise. The logic of discovery from a sociological point of view implies that conceptual change…
