Interviews 9th and 10th grade students (n=13) who studied an ecology unit and analyzed tape-recorded data for changes in organization of knowledge, represented by ideational networks and the development of higher cognitive operations. Provides insights into how students developed knowledge schemata, ideational networks, and the capacity to express…

Similarity underlies fundamental cognitive capabilities such as memory, categorization, decision making, problem solving, and reasoning. Although recent approaches to similarity appreciate the structure of mental representations, they differ in the processes posited to operate over these representations. We present an experiment that…

A 47-item structured Q-sort methodology was used to identify and analyze the frameworks held by experienced emergency response personnel. The questionnaire was designed to determine the following: the characteristics/behaviors considered important by people within specific fields of emergency response; differences between individuals within a…

Course offerings with an international focus have expanded rapidly in secondary schools in the United States in the last decade, and research is needed to explore how global and international education goals may be achieved. Four models for organizing the research agenda are presented: (1) organization around a study of influences upon global and…

A study used structure mapping theory to examine the claim that children can understand metaphors based on shared object attributes before understanding those based on shared relational structure. The three kinds of metaphor used in the study varied in whether the shared information forming the basis for the interpretation was attributional,…

This paper briefly reviews research on tasks in knowledge-rich domains including developmental studies, work in artificial intelligence, studies of expert/novice problem solving, and information processing analysis of aptitude test tasks that have provided increased understanding of the nature of expertise. Particularly evident is the finding that…

This paper presents a critique of current research on functional understanding of thinking and teaching. Three trends in cognitive research are examined. The "reification of mind" (the assumption that "mind" is an entity just as is body) is examined as a research trend that accepts knowledge as existing independent of the biographies, the…

Evidence points to a pervasive tendency for persons to behave to maintain their existing cognitive structures. One strategy by which this self-verification is made more probable involves information processing. Through attention, encoding and retrieval, and the interpretation of events, persons process information so that self-confirmatory…

How the computer as a metaphor affects our understanding of the processes of learning and teaching is explored. After describing reflection and recursion in mathematics and their roles in thinking and learning, models of the mind and teaching effects are discussed, with self-awareness as a theme. (MNS)

Examines the role of human information processing and decision-making capabilities and limitations in the design of effective human-computer interfaces. Several cognitive engineering principles that should guide the design process are outlined. (48 references) (Author/CLB)

Provides evidence for the utility of schema-based frameworks which assume that schemas and scripts organize information, aid in comprehension, and guide information retrieval. (FL)

Investigated the role of "a priori" ideas in planning experiments and data processing leading to inferences. Thirty-one students (ages 11-13) observed a "combustion/candle in a closed container" experiment and were asked to interpret sets of measurements. Findings, among others, show that children preferentially experiment on…

Using similar research in Britain as a basis, a study in New Zealand explored schema learning in young children. The primary purpose of the study was to determine the effects of a curriculum intervention designed to increase the richness and amount of stimulation teachers and parents give 4-year-olds in response to observations of children's…

Examines the place of mental models in the process of knowledge construction, particularly by the relationship between mental models and computer models in that process. Analyzes and discusses children's use of spreadsheets to build their own computer models. Suggests that the process of building models on a computer may provide direct support to…

Suggests study by Kuhn and others (PS 524 345) is too ambitious and that the processes described are not wholly representative of developmental stages. Argues the methodology of study was progressive problem solving, and that experimenter's questions resulted in contrived stages. (JW)
