Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)

Describes the use of oceanographers' models for introducing students to the concept of mathematical modeling. Outlines a lesson showing the interrelationship of science and mathematics. (RT)

Discusses the overall educational value of grouping students to enhance learning in the classroom. Describes an alternative to whole-group lecture which is referred to as cooperative problem solving. Explains staff training and procedures necessary for implementing this technique. (RT)

This study reports the preferences students expressed in regard to problem-solving modes for resolving environmental problems. There were many differences between students at different grades and between girls and boys. Implications for teaching are suggested. (YP)

Reviews three software programs: (1) "Microsoft Works 2.0": word processing, data processing, and telecommunications, grades 7 and up; (2) "AppleWorks GS": word processor, database, spreadsheet, graphics, and telecommunications, grades 3-12, Apple IIGS; (3) "Choices, Choices: On the Playground, Taking Responsibility":…

Explains a lesson in which the scientific method is used as a teaching strategy. Discusses when this approach can be used, the interdisciplinary method, and sample science concepts that can be appropriately taught this way. (RT)

How students restructured their scientific ideas in response to contradictions was studied with 166 male and female students (aged 12 to 14 years) who tested their predictions about water displacement by experiment. Conceptual change varied; all subjects tended to hold onto old ideas, even when presented with conflicting information. (SLD)

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

Five articles describe improvements in instructional software designed to enhance problem solving skills. Issues addressed include problem solving software to implement curriculum goals; problem solving theory and writing theory; software for elementary and secondary school science instruction; software for mathematics instruction; and cognitive…

Examines the problem of determining the minimum center of mass for a can with a varying height of liquid in it. Uses PC SOLVE computer software to graphically represent the problem situation. (MDH)

Describes the use of expert systems in elementary school classes that focused on developing thinking skills and independent learning. Expert systems as tools, tutors, and tutees are discussed; differences in learning styles are considered; problem-solving skills are addressed; and uses of expert systems in science and social studies are described.…

A study used computer analysis to examine distribution of basic science content in the 53 cases in the problem-based medical curriculum of Rush Medical College (Illinois) and compared it to application of that content by students and faculty. The method of analysis is recommended for reviewing curricula for omissions and redundancy. (Author/MSE)

The results of an in-depth analysis of the lab activities found in two popular high school biology textbooks are presented. Activities were rated against 24 task categories that parallel skills or behaviors which reflect scientific inquiry, problem-solving skills, manipulative skills, and observational skills. (25 references) (KR)

Described is a research-based instructional technique for teaching analogical reasoning by the use of guided LOGO programing activities. An example worksheet is provided illustrating the use of the Sternberg's four-step analogical reasoning technique (encode, infer, map, and apply) with LOGO programs. (Author/MDH)

Presents a mathematical problem that, when examined and generalized, develops the relationships between power and efficiency in energy transfer. Offers four examples of simple electrical and mechanical systems to illustrate the principle that maximum power occurs at 50 percent efficiency. (MDH)
