The role of the computer in coordinating the activities surrounding five modes of mathematics instruction is discussed. The modes are: computer-assisted instruction, computer-managed instruction, computer-based simulations, algorithmic exercise solving, and computer-aided problem solving. (MP)

Provides step-by-step instructions for constructing a simple, inexpensive microscope. Illustrated with photographs and a drawing. (MA)

Describes a computer aided analysis and subsequent assessment of analytical (pharmaceutical) chemistry data from an undergraduate laboratory course. (Author/GA)

Describes procedures that can help students to make model geodes from eggshells, copper sulfate, and other crystalforming substances. (HM)

Describes an exercise developed by the author to help college students to become familiar with the technique of photoelectric photometry of variable stars and permits each student to work with data he or she has personally obtained. (HM)

Provides background relating cardiorespiratory disease to physical activity. Three laboratory activities are described: pulse response to posture change and quiet activity, pulse response to exercise (mild increasing to strenuous), and ability to extract oxygen. The last includes information on construction of an ergometer. (CS)

Presents articles on: the measurement of flouride levels in natural waters; the effect of sunlight on the rate of chlorine decomposition in a swimming pool; and curriculum development in Australian agriculture science. (MLH)

These worksheets involve the use of tangram pieces in creating geometric shapes and in analyzing properties of convex quadrilaterals. (DT)

Discusses the legal implications of situations in which chemical educators may be liable for negligence. (MLH)

This paper calls into question prevailing approaches to educational research (contrived experiments) and proposes a new perspective in method, theory, and substance (natural experiments). (MM)

Describes the development and use of learning activity centers in the basic business classroom--an instructional approach which offers an alternative to the traditional approach and which allows maximum student involvement. (TA)

This paper describes the evolution of an approach designed to improve interpersonal interaction between spouses through training in specific communication skills. The approach can be used either in lieu of, or in conjunction with, more traditional marital counseling. Presented at American Personnel and Guidance Association Convention, New Orleans,…

Describes the use of computer-assisted graphical displays in experiments to determine the order and activation energy for a chemical reaction. (MLH)

Provides some possible ideas for music learning centers focusing on listening activities, music-making, and "potpurri". (Author/RK)

Examines the role of interpersonal needs for control and affection in influencing members' attitudinal reactions to the trainer and the group. Results indicate no support for the two-stage, authority-intimacy sequence suggested by much of the research on group development. (Author)
