Provides information on collecting and maintaining termites and for using these insects in behavioral studies (trail following, recognition, food choice, reproductive behavior, and behavior in a magnetic field) and termite control experiments (preventive construction techniques, termite repellents, using soil or wood pretreatment, and the bait…

Describes a low-cost instrument using a solar cell as a sensor to measure both instantaneous and integrated value of solar flux. Constructing and calibrating such an instrument constitutes an undergraduate experimental project, affording students an opportunity to examine a variety of aspects associated with solar energy measurements. (Author/SK)

Describes the multimedia approach used in the electronics technology program at Southern Illinois University at Carbondale, which is based on self-paced learning modules and corresponding laboratory activities. Also examines the student evaluation method which looks at students' task performance on cognitive and psychomotor levels. (CAM)

Presents specific techniques for lectures and demonstrations in acoustics for deaf students. (SK)

Provides methods for making instruments and supplies accessible to the visually impaired student in the chemistry laboratory and classroom. (CS)

Theoretical background, experimental procedures, and analysis of experimental results are provided for an undergraduate physical chemistry experiment on electron paramagnetic resonance (EPR) linewidths. Source of line broadening observed in a spin-spin exchange process between radicals formed in aqueous solutions of potassium peroxylamine…

Three experiments examined the perception of a three-way voicing contrast by monolingual speakers of English. The results demonstrate that the perceptual mechanisms used by adults in categorizing stop consonants can be modified easily with simple laboratory techniques in a short period of time. (Author/PN)

Analyzed are university instructor behaviors in introductory and advanced level laboratories of botany, chemistry, geology, physics and zoology. Science Laboratory Interaction Categories--Teacher (SLIC) was used to assess 15 individual categories of teacher behaviors in the areas of questioning, giving directions, transmitting information,…

The results of using laboratory instruction as part of the total biology program in the Biological Sciences Curriculum Study are reported. (Author/SA)

Issues surrounding the controversial topic of in vitro fertilization and artificial manipulation of reproduction are discussed. The author examines the moral and ethical implications and presents results of a survey of various religious groups. (SA)

Starting from the premise that the assessment of second language learners' competence is a must at several points during the learning process, discusses the usefulness of laboratory testing. Argues that it allows for standardized testing, facility of test administration, easy scoring, objective measures, reliability and validity of results. (MES)

Focuses on molecular weight and molecular weight distributions (MWD) and models for predicting MWD in a pedagogical way. In addition, instrumental methods used to characterize MWD are reviewed with emphasis on physical chemistry of each, including end-group determination, osmometry, light scattering, solution viscosity, fractionation, and…

The pros and cons of laboratory vs. field-based research are debated, and a university-based model program for research at the University of North Carolina at Greensboro into mainstreaming in physical education is described. (JN)

Observational data were collected on 10 industrial education student teachers in laboratory settings. Successful classroom management practices were judged as those in which a maximum amount of time is spent with students actively working on the tasks set by teacher. (SK)

Presents an overview of the university fleet, its purpose, relationship to the rest of the United States oceanographic research fleet, history, cost factors, and other information. (DC)
