Describes the introduction of some fundamental concepts of strain in beginning structural geology courses through the use of "card-deck models. Suggests this technique as a bridge between the visual, but qualitative, and the mathematical aspects of these fundamental concepts. (BC)

Laser physics can be addressed and presented at three different levels of conceptual and mathematical sophistication. In this paper, the three levels are defined and characterized. Advantages and disadvantages of each approach are discussed, and recommendations for choosing a particular approach to match student level and interest are offered.…

Describes procedure for providing practice in critical reading of scientific manuscripts based on the introduction of deliberate flaws in published research reports for students to detect and correct. (AL)

The characteristic features of the Maxwell-Botzmann energy distribution function and its variation with temperature are demonstrated using visual displays and simple counting techniques. (DT)

Discusses the tusks of the Arctic Narwhal Whale as a demonstration of chirality and diastereoisomerism in stereochemistry. (SL)

Describes a nonlecture group technique for teaching physics. Test results are compared with classes using the lecture technique. Concludes that a smorgasbord of methods will probably give the student the best educational opportunity to achieve. (Author/PR)

A seminar is described as a forum for discussion of scientific problems and as an exercise in communication. Guidelines are given for selecting and organizing the subject material, the manner and language of an oral presentation, and the use of visual aids and the voice. (TS)
