Discusses the role of laboratory work in biology and suggests reasons (mostly related to the preparation of teachers) for the continuing emphasis on confirmatory laboratory exercises rather than student directed investigations. Gives examples of process and affective objectives, and practical suggestions for using behavioral objectives to guide…

Discusses the use of games for teaching introductory physics. The elements of game design are reviewed, and sevel examples are described that illustrate different varieties of teaching games suitable for use by beginning physics students. Bibliography. (LC)

Suggests that introductory geology students, who are mostly nonmajors, would benefit if more laboratory time and the necessary microscopic examination were allowed as part of work on rocks/minerals. Indicates that students need to be taught value/necessity of paying attention to details while gathering data or making observations to make…

The theory of ecological competition, as used to explain community structure and specialization within species, also applies to the problem of coexistence among fast-food restaurants. This analogy is used in a simple laboratory exercise designed to teach competition theory and start students thinking about the urban environment from an ecological…

Fingernail growth rates are easily measured over a period of a few weeks and provide opportunities for students to improve graphing skills. Fingernail growth rates are approximately the same as sea-floor spreading rates and can be used for comparing the rates of other geological processes such as tectonic uplift. (Author/JN)

Describes classroom activities using algae, including demonstration of eutrophication, examination of mating strains, and activities with Euglena. Includes on algal morphology/physiology, types of algae, and field sources for collecting these organisms. (JN)
