Describes the cognitive processes required to troubleshoot faults and describes an architecture based on that cognitive model for designing learning environments that engage novices in troubleshooting while supporting their construction of requisite knowledge. This model can be applied to different kinds of troubleshooting problems, enhancing the…

Recent research in mathematics instruction underscores the importance of problem solving and higher-level thinking. This article presents four themes in instruction for students with learning disabilities: (1) provide a broad, balanced mathematics curriculum; (2) engage students in meaningful problem tasks; (3) accommodate diverse learning styles;…

Mental arithmetic strategies were studied with 91 Dutch third graders who computed by splitting off 10s and units in both numbers or counting by 10s up or down from the first unsplit number. Results reveal flexibility in changing between and within strategy use. Implications for instruction are discussed. (SLD)

Analyzes student performance on solution calorimetry problems in an introductory university chemistry class. Includes data from written classroom exams for 207 students and an extensive longitudinal interview with a student. Indicates learning difficulties, most of which appear to originate from failure to understand, that net increases and…

Maintains that Demetriou and his colleagues' project shows how developmental scientists can assess concepts from multiple frameworks and relate them through explicit modeling and targeted research to build explanations powerfully grounded in data and theory. Presents doubts related to specific conclusions because of issues related to the design of…

Research on the cognitive processes used by physicians during patient care (template matching, deductive logic starting with multiple hypotheses, and algorithmic logic) is examined for its applicability to optometrists and the problem-solving strategies used by optometric students in the classroom or clinic. (Author/MSE)

Two characteristics that determine problem difficulty--the nature of the move search space and its interaction with other aspects of the task--were investigated in experiments in which 26, 69, 42, and 42 community college students attempted to solve the Chinese Ring Puzzle. The origins and implications of difficulty are discussed. (SLD)

Two experiments, with 300 adult women as subjects, studied the effects of laboratory training on the use of the Conjunction Rule, a principle of probability that is often violated. Learning alternative strategies enabled trained subjects to use extensional reasoning rather than intensional heuristics. (SLD)

Contends that two of the most important goals of educational reform should be (1) narrowing the learning gap between high- and low-achieving pupils; and (2) developing in all children a greater capacity for higher-order thinking and problem-solving skills. (TE)

Analyzes the cognitive processes and kinds of knowledge needed to work in a scientific domain like physics. Discusses the processes needed to interpret scientific concepts, uses of quantitative and qualitative descriptions, hierarchical ways of organizing scientific knowledge, and processes facilitating problem solving. Describes the use of these…

Fourth-grade students (n=45) either with or without learning disabilities and achieving or not achieving at grade level in math were asked to explain strategies used to solve computational problems. Strategies were classified as reproductive or reconstructive (which varied in applicability and efficiency). Significant group differences were found.…

Two steps in the social information process model were assessed for socially accepted and rejected children by verbal responses to stories embedded in computer games. Attributions of intent and aggressive problem solutions were correlated with contextual factors (interpersonal context, outcome of game, and story type) and with sex and social…

Presents a review of literature on programing in Logo, including prerequisites of programing, cognitive effects of programing, stages of programing, and levels of programing expertise. An analysis of the literature establishes the need for operationalizing problem solving with Logo, and a research strategy to meet this need is suggested. (32…

Two groups of adolescents and a group of Coast Guard officials were interviewed about hypothetical political problems. Solutions presented were arrayed along a continuum of expertise, according to the complexity of subjects' political schemata and skills used in problem representation. (BC)

Provides a list of 33 problem-solving steps extracted from physics textbooks and arranged within the following 3 categories: setup, solution, and checks. (MDH)
