Described is a science, technology, and society (STS) segment of an elementary science methods course for preservice science teachers. An outline of a typical STS investigation is presented. Evaluation of this segment of the methods course is discussed. (CW)

States that the relationship between mathematics and physics in the first year college level might be similar for populations from different national and cultural backgrounds. Reports student responses in two schools on topics covered by a mathematics test. The similarities and differences between the two groups are discussed. (YP)

Notes that criticism of the training offered by universities to future chemists is well documented. Suggests a 17-step model for the planning of a chemistry course that utilizes a competency-based training program. Explains each step and lists sample objectives. (MVL)

Reviews some important properties of the bimolecular reaction between the hydroxyl radical and carbon monoxide. Investigates the kinetics of the reaction, the temperature and pressure dependence of the rate constant, the state-to-state dynamics of the reaction, and the reverse reaction. (MVL)

Describes a program that involved classroom instruction in advanced mathematics, a visit to the Mathematical Sciences section of Oak Ridge Laboratory, talks by faculty members on their interests, work with mentors on student research activities, and various recreational activities. Includes a list of projects and students participating. (RT)

Describes the current use of automation in the laboratory. Discusses the need, flexibility, and benefits of automation. Presents a generic system description. Lists commercially available laboratory robots. (MVL)

Presented is a comprehensible structural representation of humic substances. A number of important roles of soil organic matter, including contribution to the cation-exchange capacity, binding of pesticides, and formation of complexes with micronutrient cations, are illustrated. (Author/CW)

Lichenometry is described for use in the study of biology and physical weathering. Discussed are lichens in general and an outline for studying growth and ecology. A problem solving format is used. (CW)

Discusses the making of a light engine powered by sunlight or a lamp. Describes the materials and construction method with detailed specifications and diagrams. (YP)

Discusses some historically important reference systems including those by Newton, Leibniz, and Galileo. Provides models illustrating space-time relationship of the reference systems. Describes building models. (YP)

Discusses the use of saline solutions for demonstrations of buoyancy showing oscillations of the Cartesian diver. Describes the physical principles, preparation, and instructional uses for the demonstration. (YP)

Presents a programed method that inventories and classifies hazards. 8iscusses the following topics: (1) student and hazard source, (2) elimination of the source, (3) adaptation of the source, (4) isolation of the source, (5) adjustment of the surroundings, (6) isolation of man, and (7) personal protective equipment. (MVL)

Describes the peat to coal process. Investigates the organic, inorganic, and sulfur components of coal. Outlines how varying percentages of each are formed. (MVL)

Provides a point of view that the organic lab is a good place for the student to use and learn problem solving skills while performing the cookbook experiments. Notes that an equilibrium between the theoretical and practical aspects of organic chemistry should be established. (MVL)

Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)
