Describes the physical science courses at Lanchester Polytechnic. These courses are broad-based and offerings cover a wide range of options and use a variety of teaching-learning methods. (GA)

Describes a simple way to demonstrate the principles involved in a drinking water plant. This demonstration developed for a general public lecture can be used in chemistry and biology courses for an ecological and environmental emphasis. (HM)

Describes the multimedia student response system which has been used at Ball State University, Muncie, Indiana, in teaching biology. Specific guidelines followed in developing the multimedia student response software are also presented. (HM)

Presents several new products and equipment for teaching college science courses such as the electronic toploading balances and the hologramaker. A description of each product, cost, and addresses of manufacturers are also included. (HM)

Describes an introductory earth science course concerned with catastrophic events and processes in geology. Includes a section on lecture topics, readings, and visual materials. (MA)

Describes a freshman introductory unit that utilizes team teaching techniques and close student-faculty relationships: Faculty from the divisions of Science, Social Science, Humanities, Rhetoric, and Psychology and Counseling cooperated in the designing and teaching of the course. The science segment includes lectures and laboratory exercises. (MA)

Describes a self-paced mastery instructional computer programing course. States the objectives of the course, the way it was conducted, and the method of student evaluation. (GA)

Investigates and presents evidence concerning the construct validity of the Test of Higher Cognitive Learning in Chemistry (THCLC), a 40-item multiple-choice test developed to provide assessment of first semester introductory college chemistry students' higher cognitive skills. (Author/GA)

Advocates the use of nonparametric techniques, when teaching data analysis to undergraduate life-science students, to circumvent their poor mathematical training. (GA)

This symposium focused on the question: can colleges afford to continue offering high quality laboratory instruction at the undergraduate level. (Author/BB)

Investigates the possibility of using audio-tapes for self-study courses in technical colleges. This article presents: (1) description of the electrochemistry course taught; (2) results of the assessment of student reaction to the course; and (3) conclusions. (HM)

Describes an oscillating chemical reaction, and discusses numerous parallels to it in research, such as in fibrillation of the heart, body-clock rhythms of animals and plants, the self-assembly of multicellular organisms, and certain stripes in volcanic rock. (GA)

Presents a calorimetric experiment designed to clarify some of the basic physics of heat transfer and insulation. (GA)

Discusses free-radical organic conductors and semiconductors, contrasting them with familiar classes of solids such as metals, magnetic insulators, and molecular solids. (Author/GA)

Describes the intuitive approach used in general chemistry and points out its pedagogical advantages. Explains how to extend it to acid-base equilibrium calculations without the need to introduce additional sophisticated concepts. (GA)
