This paper describes a computer model that simulates the way children develop the reasoning skills of transitive inference and the construction of ordered sets. The computer model begins from general operations, such as setting and removing goals, storing and retrieving information, comparing elements to find matches, reading premises, and giving…

In all likelihood, computer use in early childhood will continue to increase. However, there is reason for concern about how computers will be placed into classrooms, what activities will be chosen for children, what interactions will take place, and whether these interactions will consider appropriate readiness and development levels. Computers…

This study focused on the cognitive conflicts experienced by young children in using software programs that provided them with tools to create and/or combine individual graphic elements into larger structures. Six 5-year-old children, none with prior computer experience, were observed using three programs--Kids at Work, Picture Perfect, and…

This paper discusses a model of information storage and retrieval, the k-d tree (Bentley, 1975), a binary, hierarchical tree with multiple associate terms, which has been explored in computer research, and it is suggested that this model could be useful for describing human cognition. Included are two models of human long-term memory--networks and…

Word processing programs offer five capabilities that can help students over the physical and psychological constraints associated with writing. First, producing text on a word processor is more tentative and more noncommital than producing text on paper. This reassures the writer that it is all right to experiment with words. Second, the blinking…

This paper argues that the microcomputer has a place in early childhood education when it is coupled with microworld software. Microworld software formats are open-ended, user-designable, child-oriented software experiences providing children with direct access to specific concepts and the opportunity to exercise those concepts in meaningful ways.…

This paper identifies several reasons for the gap between the possible instructional uses of computers and their actual use in classrooms and discusses considerations in planning programs which will bring computer education closer to its envisioned promise. The Assessing the Cognitive Consequences of Computer Environments for Learning (ACCCEL)…

Four classes of high school chemistry students (N=108) were randomly assigned to experimental and control groups to investigate the effectiveness of a computer assisted instruction (CAI) package during a unit on writing/naming of chemical formulas and balancing equations. Students in the experimental group received drill, review, and reinforcement…

This paper provides an historical perspective on the possible roles of cognitive technologies in thinking as "reorganizers" of the mind. It suggests that by understanding the transformational roles of advanced technologies for mathematical thinking, positive contributions can be made to research and practice on the use of computers in…
