The purpose of the present paper is to examine the socio-cultural foundations of technology-mediated collaborative learning. Toward that end, we discuss the role of artifacts in knowledge-creating inquiry, relying on the theoretical ideas of Carl Bereiter, Merlin Donald, Pierre Rabardel, Keith Sawyer and L. S. Vygotsky. We argue that epistemic…

Reports on two studies on the dynamic relationships among parts of a thought system. The first study examines the effects of changes in the desirability or likelihood of a core event on thoughts about antecedents and consequences; the second examines the effects of changes in the antecedents and consequences on the core thought.

Reexamines the studies of K. S. Dobson regarding metaanalysis of cognitive-behavioral therapy for depression using the Beck Depression Inventory as an outcome measure. Confirms Dobson's conclusions but shows that about half the difference between CT and other treatments was predictable from researcher allegiance. Comparable analysis of a later set…

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…

Examined the concept of vocational development in relation to structural changes which occur in the cognitive schemata individuals use to process vocational information. Results from 101 college undergraduates indicated that vocational decision-making skills, career exploration, and career planning varied as a function of cognitive structure.…

Presents study results suggesting some malleability in learning strategies that flow from cognitive style. Examines the effects and practicability of restructuring training as a means of addressing individual learner differences. Reports that training enhanced performance on two dependent measures tasks. Concludes that field-dependent learners…

Ability to represent life-size space in a small scale was examined by asking 4-year-olds to create a small-scale model of a familiar preschool classroom. Study 1 children with high or low restructuring ability completed the model under guided or nonguided format. Guidance given to Study 2 children emphasized a functionally clustered classroom…

Cognitive structuring was implemented by showing 30 subjects a 10-minute videotape that presented Holland's (1985) model of the world of work before they used an interactive computer-assisted guidance system (DISCOVER). The effect of prior structuring was assessed in terms of a subject's representation of the world of work, occupational certainty,…

Discussion of computer-assisted career guidance (CACG) focuses on a study that examined how cognitive structuring intervention before using a CACG system would affect subjects' occupational certainty and vocational identity. The DISCOVER system is described, Holland's hexagonal model is discussed as the intervention, and further research needs are…

Reconstructs the process through which a student becomes familiar with new subject matters and unfamiliar rhetorical and linguistic conventions. Describes one writer's attempt to achieve "specialized disciplinary literacy." Suggests the writer must be able to integrate his/her knowledge of appropriate discourse conventions with a…

This study, with 26 deaf and 26 pair-matched hearing preschool children, first assessed their cognitive modifiability using dynamic and static-convention instruments, and then compared the factorial pattern of the cognitive measures in both groups. Results are interpreted according to the Structural Cognitive Modifiability and Mediated Learning…

The broad focus of this study was on the role students' existing conceptions play in the process of constructing and understanding mechanics concepts. The study was a naturalistic one, conducted over a number of years, at all grade levels, in one all-boys secondary school in Australia. In particular it was concerned with identifying and…

This document examines children's and adults' knowledge of observational astronomy and characterizes the kinds of mental models students form when asked questions in astronomy. Mental models were grouped into three categories: intuitive, synthetic, and scientific. Implications for the design of curricula and for instruction are identified. In…

This study develops and employs the construct, personal orientation to science learning, to study the processes by which children construct meaning as they learn science in school. The theoretical bases of the thesis are the commitments of a constructivist view of learning and the psychological framework of George Kelly's Personal Construct…

Reports a study to investigate the extent to which research experience of designing and conducting their own study could enhance five preservice teachers' understanding of children's knowledge of the mathematical concept of fractions. Results indicated that research experience is fruitful in developing an inquisitive disposition in preservice…
