Examined student behaviors during laboratory activities and the amount of time involved in each behavior. Approximately 89 percent of the student time was spent interacting with others. The amount of time spent on various activities appeared to be dependent on the nature of the activity and on the make up of the laboratory group. (YP)

Described are two methods which use microcomputers to illustrate the use of the electrocardiogram and the function of the heart. Included are a simulation and a method of collecting live electrocardiograms. Hardware, software, and the use of these systems are discussed. (CW)

Described is a project in which information about the moral issues surrounding tissue transplants was obtained and videotaped for classroom use. Moral positions and possible educational strategies are discussed. Examples of student statements are presented. (CW)

Eight articles are included in this collection. Topics include: multicultural science, teaching science with metaphors, development of a graded assessment scheme in science, relative performance of boys and girls in chemistry, promoting science understanding, formative evaluations, science background of primary teachers, and promoting creativity…

Surveyed 1200 students in a second semester general chemistry course at Purdue. Investigates areas where student and faculty perceptions of the content of chemistry courses differ. Elaborates on each area and suggests explanations for the findings involved. (MVL)

Discusses some of the contributing factors and chemical reactions involved in the production of acid rain, its effects, and political issues pertaining to who should pay for the clean up. Supplies questions for consideration and discussion. (RT)

Uses a modular approach so the Local Area Network (LAN) can be easily dismantled and reassembled for each class. Notes the course is evolving to keep pace with rapid advances in networking technology although only in its second year. Expands the basic LAN through the addition of second generation personal computers. (MVL)

Discusses a device that enables computer images to be projected using an overhead projector. Describes possible uses for the liquid crystal displays (LCD) along with its advantages and disadvantages. Provides several suggestions for purchasing an LCD. (MVL)

Discusses under what conditions computer simulations should be used. Considers the aspects and qualities of computer simulations used in simulating science laboratory experiments. Provides suggestions for selecting or designing simulations. Examines the idea of transfer when using simulations. (MVL)

Lists a program for a simulation of Rutherford's gold foil experiment in BASIC for both Apple II and IBM compatible computers. Compares Rutherford's model of the atom with Thompson's plum pudding model of the atom. (MVL)

Reviews seven papers presented by the Technical Committee for Education of the International Federation for Information Processing. Topics consider: undergraduate physics, high school optics, a mathematics lab with LOGO, simulations and modeling for secondary education, computer assisted instruction with biology, and mathematics of tomorrow. (MVL)

Provided is an empirical method to train students to avoid physical disaster in their work experience. Discussed is a computer program, CHETAH, which can be used in advance of synthesis to classify the possible explosive nature of the products. Plosophoric and auxoplosive weights of many organic groups are listed. (MVL)

Described is a course which combines the usual instruction in technical subjects of industrial chemical operations with some of the business aspects that compose the total commercial enterprise. The two-hour-a-week semester course syllabus is provided. A business game to develop a plan for business expansion is included. (MVL)

Described are three chemistry demonstrations: (1) a simple qualitative technique for taste pattern recognition in structure-activity relationships; (2) a microscale study of gaseous diffusion using bleach, HCl, ammonia, and phenolphthalein; and (3) the rotation of polarized light by stereoisomers of limonene. (MVL)

Discusses the Bradford Plan's general education core curriculum which includes a course in scientific literacy. Advocates an understanding, awareness and appreciation of the science field. Provides the course objectives and outline. (MVL)
