Randomly selected high school students (n=13) who studied an ecology unit were interviewed, and narrative data analyzed for changes in knowledge schema. Data support the current theory that the amount and quality of prior knowledge substantially influence gains in new knowledge and are closely linked to a capacity to apply higher-order cognitive…

In two experiments, affect-based and cognition-based attitudes toward a person were induced by varying sequence of affective and cognitive information presented to subjects while holding content constant. Results indicated affect-based attitudes were most effectively changed by affective persuasive appeals, whether these appeals were produced by…

Draws on recent work leading to new conceptions of learning, induction, transfer, and strategy acquisition. Contends learning is no longer simply the acquisition of behaviors, but also includes storing knowledge about relations in the world, and acquiring structural representations and mental models. Sees learning and the growth of processing…

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)

Suggests that the study of memory needs to be situated within broader conceptual and research contexts. Examines how four contexts accommodate memory phenomena: (1) knowledge; (2) comprehension; (3) context/function; and (4) strategy. Suggests that memories are best examined as knowledge structures resulting from efforts to understand, and that…

Interacting cognitive subsystems (ICS) is proposed as a unified cognitive theory that can be used as the basis for representations in human-computer interaction, and two approaches based on the theory are described: one entails the description of cognitive task models, and the other entails the production of less complete diagrammatic notations.…

Addresses issues related to the ways teachers learn mathematics and the teaching of mathematics, and the relevance of those ways to their professional development. Mathematical experiences need to be congruous with the kind of teaching expected of the reflexive, adaptive teacher. Presents both practical and theoretical considerations of how these…

Discusses what important ideas about forms of knowing mathematics should be included in mathematics methods courses for preservice teachers. Proposes ideas related to Shulman's framework of teacher knowledge. Provides a brief discussion of the implications each idea holds for teaching mathematics, and makes some suggestions about experiences that…

Identifies middle school and college students' prior ideas about electrostatic induction. Presented students with observational evidence that supported or refuted their own prior ideas in an interview format. Concludes that the Lakatosian rather than the Popperian view is more acceptable in understanding students' responses to conflicting…

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

Two experiments show that action alters the shape categories formed by 2-year-olds. Experiment 1 shows that moving an object horizontally (or vertically) defines the horizontal (or vertical) axis as the main axis of elongation and systematically changes the range of shapes seen as similar. Experiment 2 shows that moving an object symmetrically (or…

This paper presents preliminary results of research founded on the hypothesis that in real environments there exist regularities that can be idealized as mathematical structures that are simple enough to be analyzed. The author considered three steps in analyzing the encoding of modularity of the environment. First, a general information…

The conceptions of information needs of seven American and seven Swedish mechanics employed by a Swedish multinational machine industry are compared by using perspective text analysis to analyze their verbal responses to three open-ended questions concerning their need for work-related information. The structures embedded in the texts are…

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…
