Describes an artificial intelligence system known as SOAR that approximates a theory of human cognition. Discusses cognition as problem solving, working memory, long term memory, autonomy and adaptability, and learning from experience as they relate to artificial intelligence generally and to SOAR specifically. Highlights the status of the…

The time may be ripe for the fields of mathematics education, special education, and cognitive psychology to converge, with their respective focuses on mathematical problem solving, individual differences among students, and analysis of cognitive processes. Four articles on learning disabilities in mathematics are introduced, and a research agenda…

Exposure of an experimental group of (n=33) college freshmen to teaching experiments dealing with stoichiometry problems based on the concept of limiting reagent showed greater improvement in posttests than the (n=39) student control group and observed that some students protect their core beliefs by ignoring conflicting data. (Author/MKR)

Proposes causal field theory as a model of causal reasoning. Suggests that anomaly detection through comparison with natural events triggers causal reasoning. This anomaly is interpreted in terms of agency; therefore, natural phenomena can be understood through an appeal to agency. The mechanism proposed never changes with development, whereas…

Examined the relationship of maternal interaction and private speech to task performance, using a sample of four- and five-year-old children. Findings underscore the positive, self-regulatory function of private speech, highlight the role of adult communicative support in extending the child's competencies, and call attention to the cognitive and…

Examines research on computers as cognitive enhancers, focusing on applications software that includes spreadsheets, graphing, and databases. Appropriate computer-based problem-solving environments for young children are reviewed, and implications for teachers are suggested. (Contains eight references.) (LRW)

Examined differences in cognitive and metacognitive processes of 40 high- and low-mathematics-ability students in grade 12 as they solved 5 everyday mathematics problems. Competence in problem solving was characterized by a rich knowledge base, metacognitive strategies, and confidence. Boys and girls exhibited different cognitive structures for…

A total of 87 children, 3- to 7-years old, were examined in a study of children's play and reasoning in games of mathematical logic and social logic. Children's sophistication in reasoning was positively related for two games, suggesting a common three-level progression from mastery of procedures to a competitive attitude to advanced strategy. (SH)

Discusses the use of microcomputer applications software in education, reviews the literature involving studies on the development of problem-solving skills and on the instructional use of spreadsheets, and describes a project for secondary school students using spreadsheets that provides cognitive support. (Contains 35 references.) (LRW)

A 5-year study investigated the effect of training on question-asking skills of 42 licensing examiners in orthopedic surgery. Results indicate that a three-hour training session resulted in examiners' asking many more open-ended and/or problem-solving questions, suggesting the effectiveness of the training program. (Author/MSE)

Argues that educators should reconsider their current commitment to problem solving as the way to promote constructionist teaching and learning and should focus on teaching important ideas developed within the disciplines. This idea-based social constructivism focuses on the possibilities of a given situation. (SLD)

Focuses on the responses of elementary school children (N=336) to an "Awareness of Technology Survey" question intended to explore how they would begin the technological problem-solving process. Contains 29 references. (DDR)

Presents evidence for students' qualitative and quantitative difficulties with apparently simple one-dimensional relative-motion problems, students' spontaneous visualization of relative-motion problems, the visualizations facilitating solution of these problems, and students' memories of the online computer simulation used as a framework for…

Explores the arguments used by 14-year-old students in making decisions about the design of a road in their area. Describes the general perspective of such an approach and the process of argumentation, then analyzes the nature of the students' arguments which are discussed on the basis of a specifically-constructed network. Contains 20 references.…

Two studies examined abstract conditional reasoning. Findings indicated an increase in use of formal justifications with grade, and that abstract reasoning was facilitated by realistic context. Findings supported the idea that such reasoning may represent a qualitative change in reasoning abilities and that its development relies on appropriate…
