Examines two computer interfaced lab experiments: 1) discusses the automation of a Perkin Elmer 337 infrared spectrophotometer noting the mechanical and electronic changes needed; 2) uses the Gouy method and Lotus Measure software to automate magnetic susceptibility determinations. Methodology is described. (MVL)

Proposes that higher education insist more on the education of its chemists and less on strictly instrument training. Lists several instances where education may have been more useful than the strict training military officers received. Discusses the role of chemists in society. (MVL)

Examined is the use of the microcomputer as a tutor, for simulations of experiments, and to provide graphic interpretations of abstract concepts in the college biology setting. Discussed are computer enhanced courses being used, the software library, and the computer laboratory facility. Lists reasons for adoption of computer enhanced format. (MVL)

Studies the use of computers in elementary schools as reported by principals in a survey. Discusses the survey instrument and its topics. Reports findings on drill and practice, learning new material, simulations, and problem solving. (MVL)

Compares achievement effects and time-on-task generated for computer and non-computer versions of essentially the same game. Notes that students followed different rules for the same game and pace was faster for computer versions. Reports transfer of instruction may not be complete. (MVL)

Provides listings of general and specific recommendations that can be used by individual teachers, curriculum specialists, and school districts wishing to develop Science-Technology-Society materials adaptable to the needs of urban students. (RT)

Describes a graduate engineering course which specializes in model predictive control. Lists course outline and scope. Discusses some specific topics and teaching methods. Suggests final projects for the students. (MVL)

Reports a study comparing various combinations of the English language with the local language for science instruction in three Kenyan primary schools. Concludes that science concepts were acquired more effectively when English was used in combination with local language and recommends implementation of a language of instruction policy. (LS)

Discusses a computer assisted learning system for engineering statistics based on personalized system of instruction methods. Describes the system's network, development, course structure, programing, and security. Lists the benefits of the system. (MVL)

Discusses the history and development of Plasma Desorption Mass Spectrometry to determine molecular weights and structures of proteins and polymers. Outlines theory, instrumentation, and sample preparation commonly used. Gives several examples of resulting spectra. (ML)

Clarifies the roles of a practicing analytical chemist in industry: quality control, methods and technique development, troubleshooting, research, and chemical analysis. Lists criteria for success in industry. (ML)

Describes a technique for separating samples that range over 15 orders of magnitude in molecular weight. Discusses theory, apparatus, and sample preparation techniques. Lists several types of field-flow fractionation (FFF) and their uses: sedimentation FFF, thermal FFF, flow FFF, electrical FFF, and steric FFF. (ML)

Identifies a common laboratory problem that causes instrumentation malfunction. Provides numerous experiences of researchers whose results have been affected by humidity fluctuations, magnetic field fluctuations, trucks driving by, and other factors. (ML)

Examines whether participation in physical experiments together with social interaction with adults and school-mates favor the development of causal knowledge and the understanding of a complex physical subject. Concludes that the treatments can lead students to give up pre-causal explanations and to resort to physical ones. (Author/YP)

Investigates use of positron emission tomography (PET) to study in-vivo metabolic processes. Discusses methodology of PET and medical uses. Outlines the production of different radioisotopes used in PET radiotracers. Includes selected bibliography. (ML)
