Describes the structure of a course for improving oral communication skills of engineering students. Lists suggestions to speakers on preparation, organization, and presentation of material. Additional comments regarding critiques are stated. (RT)

Describes an experiment that provides a fundamental understanding of the kinetics of the enzyme papain. Discusses background, materials, procedures and results. Mentions analogous experiments that can be conducted with enzymatic contact-lens cleaning solutions. (CW)

Described is a microcomputer with two detection systems to enable three variables of the puck's motion to be recorded simultaneously: speed, radius of the orbit, and the ongoing time of measurement. Presented are the experimental setup, a discussion of the computer program, and results. (YP)

Describes how to make a superconducting pellet for classroom use. Details two tests that can use the pellet to demonstrate superconductivity. Discusses some of the mechanics and chemistry of superconductivity. Lists materiads and equipment necessary for these activities. (CW)

Reports on a study designed to determine the effectiveness of two video programs with an audience of varied ages, grade levels, and developmental levels. Indicates that a significant difference was found between concrete, transitional, and formal operational students on pretest scores and developmental levels and results on the posttest. (RT)

Announces the incorporation of a laboratory information management system (LIMS) into the academic environment. Describes the applications of a computer-automated laboratory system at one university. Stresses the benefits to students of the use of such a system in terms of entry into the industrial environment and to professors in grading. (CW)

Discusses the problems inhibiting the path toward a nationwide computer network for research and education. Explains the need and urgency for establishing such a system. (RT)

Provides an overview of basic and applied studies for which primates are appropriate subjects. Summarizes the advantages, limitations, and constraints of using nonhuman primates in research. (RT)

Considers the applicability of the simple emersion/weight-gain method for predicting diffusion coefficients, solubilities, and permeation rates of chemicals in polymers that do not undergo physical and chemical deterioration. Presents the theoretical background, procedures and typical results related to this activity. (CW)

Suggests an approach and methodology for analyzing field and laboratory populations. Describes an experiment using mustard to show how competition and inequality can be assessed. Discusses the variables responsible for determining the abundance of organisms. (CW)

This article describes a computer simulation of bacterial physiology during growth in a chemostat. The program was designed to help students to appreciate and understand the related effects of parameters which influence plasmid persistence in bacterial populations. (CW)

Reports on a portable video color camera that is fully suited for seeing ultraviolet images and offers some expanded viewing possibilities. Discusses the basic technique, specialized viewing, and the instructional value of this system of viewing reflectance patterns of flowers and insects that are invisible to the unaided eye. (CW)

Describes an apparatus capable of measuring absolute temperatures of a tungsten filament bulb up to normal running temperature and measuring Botzmann's constant to an accuracy of a few percent. Shows that electrical noise techniques are convenient to demonstrate how the concept of temperature is related to the micro- and macroscopic world. (CW)

Presents a refined method for designing a valid and reliable Likert-type scale to test attitudes toward the generation of electricity from nuclear energy. Discusses various tests of validity that were used on the nuclear energy scale. Reports results of administration and concludes that the test is both reliable and valid. (CW)

Discusses the teaching of electron configurations and various systems used to help students write them correctly. Presents an approach to this type of instruction which uses diagrams and mnemonic devices. Examples of exercises which encourage the use of this method are provided. (TW)
