Describes the construction of a calorimeter to be used in an experiment which consists of measuring the rate at which ground level solar radiation raises the temperature of the metal in the calorimeter. (GS)

Explains two approaches for stimulating the intellectual development of the student from the concrete to formal operations level. One method involves experimentation and critique during which the student deduces the principle. The second involves a lecture approach that utilizes the creation of the discrepant event. (GS)

Describes an experiment designed to augment textual materials conducive to the inquiry approach to learning. The experiment is the culminating experience in a series designed to illustrate the fundamental nature of the atom: its quantized energy nature, its electrical nature, and its combining ability. (Author/GS)

Presents abstracts of the plenary lectures and contributed papers of a conference that covered the following areas: laboratory organization, integrated laboratory, instructional aids and equipment, computers, and general chemistry laboratory. (GS)

Describes an experiment for recording holograms using a minimum of costly apparatus. Includes a description of apparatus and materials, the procedure for recording the hologram, the processing of the hologram, and the reconstruction of the image. (GS)

Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Presents nine experimental studies investigating auditory and visual discrimination in very young infants. Results are discussed in terms of their implications for understanding habituation, cross-modal stimulation, receptive language development, and individual differences. Appendices include data on visual fixation duration and information on…

Describes self-paced freshmen courses in electronics using study guides with questions answerable entirely from laboratory measurements. Discusses the problem of supplying students with needed results of evaluation quickly. No statistics are included. (GH)

Describes a combined demonstration and student experiment course to illustrate fundamental techniques, instrumentation, and concise report writing. Describes experiments including tensile tests, heat treatment, equilibrium diagram, microexamination, strain measurement, and recrystallization. (GH)

Describes an undergraduate experiment. Discusses a model for the behavior of bubbles under differing viscosities and pressure gradients and conditions for failure of the model. (GH)

Presents a flowchart that is used in the elementary qualitative analysis of a single salt. (GS)

Presented before the General Session, as part of the Research Symposium, American College Health Association, Forty-sixth Annual Meeting, Minneapolis, Minnesota, May 3, 1968.
