Describes an experiment using chromatographic techniques on aging leaves which gives high school biology students the opportunity to observe, question, and formulate hypotheses. (CS)

Describes a method for undergraduate physiology students to measure plasma volume by the dye dilution technique, in which a computer is used to interpret data. Includes the computer program for the data analysis. (CS)

Describes a two-quarter hour college chemistry course focusing on laboratory safety. Includes lists of topics/assignments, problem sets (toxicology, storage, and energy) and videotapes, films, and slide sets used in the course. (JN)

Identifies factors which affect students' attitudes toward the use of animals in research and in learning biology. Responses of students (N=577) in grades 5, 7, 9, and 11 to questionnaires were analyzed by two-way analysis of variance by grade level and sex. Results and implications are discussed. (CS)

Under a National Science Foundation CAUSE grant, the Department of Computer Science and Engineering at the University of South Florida, Tampa, is developing an interactive microcomputer/minicomputer/video disk learning system for engineering and science students. Journal availability: Educational Computer, P.O. Box 535, Cupertino, CA 95015.…

Determined the effectiveness of the use of the language laboratory to teach counseling skills. A 52-minute self-instructional training tape program was developed in which a reflection of feeling was modeled. Results showed that the self-instructional tape program is an effective procedure for teaching counseling skills. (Author/RC)

Evaluated and described is an innovative freshman chemistry one-semester laboratory, relating changes in the course to objectives in decreasing lab expenditures, increasing learning, increasing quality, improving attitudes, and producing materials for widespread use. Lists topics for experiments, videotape presentation, and computer simulation.…

Reviewed research on the effect of the presence of other people on individuals' willingness to help in an emergency. Attention was paid to the nature of the precipitating incident; ambiguity of the helping situation; laboratory versus field settings; characteristics of subjects, victims, and bystanders; and communication among bystanders.…

Several experiments are described using common laboratory apparatus and readily available materials to generate resonance spectra of air columns. The advantages of this apparatus and method of demonstration are visual impact and accuracy of results. (CS)

AADS curricular guidelines suggest objectives for these areas of dental auxiliary radiology: physical principles of X-radiation in dentistry, related radiobiological concepts, principles of radiologic health, radiographic technique, x-ray films and intensifying screens, factors contributing to film quality, darkroom, and normal variations in…

Described are different chemistry curricula that use lecture-experiments. Different components are discussed within the lecture-experiment format, such as determinism, memory, note taking, descriptive chemistry, and holistic chemistry. Also discussed are different personalities in chemistry education. (DS)

Described is a science experiment involving the isolation and study of microorganisms. Bacteria from the mouth are cultured on blood agar culture plates and are then exposed to four different mouthwashes to test their effectiveness. (DS)

Provides a coding system, with flow charts, for "Hazchem," which provides an application of the knowledge of chemical behavior to emergency situations. (CS)
