Presents the ninth story in a series of chemical mysteries with emphasis on forensic chemistry, physical properties, and qualitative organic analysis. The mystery centers around the adventures of Sherlock Holmes. (DDR)

Explains how critical thinking, communication, and estimation can be incorporated into an exciting problem-solving unit for first-grade students. Presents four related activities. (ASK)

Examines the attitudes of physics instructors on how and when students should be allowed access to textbook problem solutions. Presents a detailed analysis of 249 survey responses from U.S. and Canadian universities which conveyed a wide range of opinions and comments. Discusses the need to rethink strategies regarding access to solutions. (AIM)

Discusses the main features of hypermedia and its significance in the application to education. Highlights include multimedia teaching materials; interaction; convenience in storing and using information; problem solving and critical thinking; individuality in study; and the design of nodes and links in hypermedia. (Author/LRW)

Ten-year-old students (n=531) from the U.S. and Germany were studied to determine the relationships between everyday experience, domain-specific control beliefs, acquisition of science knowledge, and solving of everyday technical problems. A causal model, developed and tested through structural equation modeling, showed that domain-specific…

The model currently guiding educational policy development--constructing crises and crafting solutions--has a long, unproductive history. To shrug off American education's perpetual crisis mode, educators should expand their descriptive vocabularies, apply the "so what" test, adopt demonstrably effective solutions, eschew a crisis…

Describes the mental coding processes involved in the flow of information when the user is interacting with an enabling information-retrieval (IR) system, or a system designed to stimulate the user's grasping towards a higher understanding of the information need/problem/task that brought the user to the system. (Author/AEF)

Reviews research focusing on problem-solving deficits and their relationship to suicidal behavior and considers some of the methodological problems that arise. Discusses findings in terms of active versus passive problem solving, state or trait factors, and the psychological processes underlying problem solving. (Author/JDM)

Describes a model for designing learning environments that engage learners in solving problems and can be delivered at a distance via the World Wide Web. Applies the model to a constructivist learning environment for an undergraduate management course on aggregate planning. (Author/LRW)

Investigates several problems with the sequences of numbers known as the Catalan numbers and the Bell numbers. Finds that the problems are appropriate for both pre- and in-service teachers, as well as students studying discrete mathematics. (Author/CCM)

Examines the relationships among the sociability of children, their dyadic problem-solving behavior, and their subsequent level of individual performance. Finds that sociable children more often initiate collaboration; less sociable children exhibit more individualistic behavior; and collaboration effects on individual performance vary by the…

Explores possible reasons for the gender differences in mathematics problem-solving strategies found in primary-grade students in the study by E. Fennema and others and considers implications of the findings for mathematics instruction. (SLD)

Considers implications of the findings of the study by E. Fennema and others that boys in the primary grades use different mathematics problem-solving strategies than girls and suggests that equitable mathematics instruction may require specific attention to gender differences and underachieving groups. (SLD)

Three studies examined the relationship between specific forms of preschoolers' social and pretend play and divergent/convergent problem solving. Naturalistic and experimental designs were used to provide clearer account of relationship and to challenge assumption of single direction of influence. Results support complex reciprocal causality model…

Describes the use of thought-provoking essay questions such as "How does one determine the temperature at which Hell freezes over?" to promote better communication skills among chemistry students. Makes reference to and suggests other thought-provoking questions. (WRM)
