Discusses a student project for the control of environmental pollution. (RK)

In a two-person experimental task used in the study of age and cultural differences in the cooperative-competitive behavior of children in a small Mexican town and in California, a higher level of cooperation was seen among Mexican than among Anglo children, as was also an increase in nonadaptive competition with age among the latter.

Authors outline the advantages of using a cyclical approach of instrumented learning and compare it with the traditional classroom method. (Editor/MB)

The language-experience approach to problem solving is discussed. A theme park unit provides illustrations of how problem solving can be developed. (MNS)

Considers how elementary school classroom teachers can employ exploration methods (gathering, evaluation, and synthesis of data related to a specific topic) to help students develop readiness for intellectually complex problem solving. (Author/DB)

Presents experiments to introduce students to the phenomenon of biological rhythmicity and to reinforce the fact that there are differences in the physiology of human beings. (Author/MA)

A technique is illustrated for solving relative motion problems using a maneuvering board and vector algebra. The technique can be used to visually illustrate properties of vector algebra in a non-theoretical context. (MP)

Five calculator activities are described that are designed to explore ordered operations. Suggestions are given on mathematical objectives, strategies for solving, and possible extensions or follow-up activities. (MP)

Problems are discussed in which addition facts are presented using words instead of numbers. The letters are then replaced by numbers that will make the addition problems correct. (MP)

Reports on a class activity in which students wrote letters to leaders and personalities in the fields of art, literature, and politics to solicit bits of their "trash" for a student art show. (RL)

Describes a system of heuristics for problem solving and instructional methods for presenting it to secondary school students. (CS)

Describes a simulation, "Ethics for Administrators," which is designed to help the student understand why he takes certain ethical positions and not others, and to challenge him to identify the systematic elements within his professional ethics. (Author/CK)

Definitions of estimating and approximating are given and areas where these skills are used (such as practical situations, problem solving, and measurement) are discussed. Nine activities which range from second to twelfth-grade level are suggested. (MK)

Brainstorming is suggested as one approach to problem solving. Generating possibilities stimulates creative and independent thinking and can facilitate problem solving in many situations. (MP)

Two posters are given containing sets of problems that are designed to stimulate interest in problem solving. Suggestions are given for the use of the posters. (MP)
