Describes a demonstration of light pipes using low-cost materials, relating it to fiber optics communication. Also provides several experiments in hydrostatics and hydrodynamics using the materials for light pipe. (JM)

Describes the plan submitted by the Nuclear Science Advisory Committee to the Department of Energy and National Science Foundation urging construction of an ultrarelativistic heavy-ion collider designed to accelerate nucleon beams of ions as heavy as uranium. Discusses the process of selecting the type of facility as well as siting. (JM)

Suggests a method treating geometric optics using a microcomputer to do the calculations of image formation. Calculations are based on the connection between the composition of lenses and the mathematics of fractional linear equations. Logic of the analysis and an example problem are included. (JM)

Summarizes research information reported on the topic of environmental studies at the college level, profiling historical and theoretical developments, discussing the problem of discipline-oriented versus interdisciplinary-oriented program development. Studies selected were chosen as representative and reflective of the variety of current…

Discusses two procedures for the identification of nitrate, the standard test ("Brown Ring" test) and a new procedure using triphenylbenzylphosphonium chloride (TPBPC). Effectiveness of both procedures is compared, with the TPBPC test proving to be more sensitive and accurate. (JM)

Outlines use of electrode potential diagrams in a simple system and in the Hill-Bendall scheme for photosynthesis to help students understand reaction mechanisms involved. Emphasizes use of arrows to depict electron transfer, concept of free-energy diagram, and that maximum heights on diagrams represent maximum work available/minimum work…

Reviews several sources of published materials which contain learning objectives for general problem solving as well as problem solving in mathematics, science, and computer science. Lists of objectives are included where appropriate. (JN)

Data are presented that indicate Blacks have not traditionally entered many scientific and technological fields. A sub-sample of 79 Black college freshmen was surveyed. Competence in mathematics was a significant factor related to their achievement, and some attitudes seemed important. (MNS)

Discusses a cooperative education program developed for undergraduate students who attend the university for five years, completing the requirements of their university degree as well as 24 months of work experience. Student, faculty, and industry roles in the program and some effects/results of the program are considered. (JM)

Reviews a noncommercial educational game (Polymerlab) and changes made in GASLAWS (adaptation of mainframe program used in computer-assisted instruction). Describes programs on simulation of molecular speed distributions; interfacing microcomputers to make laboratory measurements; a course in microcomputer-instrument interfacing and measuring and…

Explains the procedures used in a general botany course to obtain polarization, fluorescence, and dark field images using a standard student microscope. Provides sources for materials and references. (JM)

Reports research supporting the hypothesis that concrete-operational college students playing the game Master Mind with an observer where there is verbal interaction designed to stimulate thinking about the problem-solving situation will show greater cognitive growth than subjects not playing the game. Implications for science instruction are…

Discusses types of mass media suitable for use in science classrooms. Types of media, limitations, and instructional strategies are provided. Also provided are three case studies illustrating their use. Comments on making media available to students and an annotated list of several resources are included. (JN)

TESTOR is a computer-assisted testing system that provides student evaluation while simultaneously managing all records associated with a program of individualized instruction. Use of TESTOR in a general biology program, at the University of Missouri, is described. (JN)

Examines present and future applications of computers in high-energy physics. Areas considered include high-energy physics laboratories, accelerators, detectors, networking, off-line analysis, software guidelines, event sizes and volumes, graphics applications, event simulation, theoretical studies, and future trends.
