Describes the procedure, the circuitry, and the calibration required to convert a voltmeter into a pH meter for use in the physics laboratory. (GA)

A kit is described for use in automation of routine chemical research procedures. The kit uses sensors to evaluate the state of the system, actuators which modify the adjustable parameters, and an organ of decision which uses the information from the sensors. (BB)

A model is needed for defining, operationalizing, and measuring teacher competence that combines the methodological rigor of the behavioral objectives approach with the richness of the intuitive, empirical, and theoretical knowledge of what constitutes competence. (Author)

Presents an inventory instrument designed to facilitate conversation, communication, and assessment of programs and goals in secondary science teacher education. (SL)

Discusses the calibration of bolometric and photoelectric devices utilized for the measurement of solar energy. (SL)

Discusses some of the new physical dating methods being used by archaeologists and paleoanthropologists to study the material remains of ancient primates. Describes the quaternary physical dating techniques, advances in radiocarbon dating, and the radiocalcium data method. (TW)

Describes a course in chemical instrumentation for high school chemistry teachers, paid for by Union Carbide. Teachers used spectrophotometer, nuclear magnetic resonance spectrometer, atomic absorption spectrograph, gas chromatograph, liquid chromatograph and infrared spectrophotometer. Also describes other teacher education seminars. (JM)

Discusses the use of an external analog-digital converter to use a computer as a storage oscilloscope. Provides program listings for use as a unipolar or bipolar voltmeter and storage oscilloscope. Schematics and component list are included. (JM)

Presents highlights of a December 1985 report on Soviet scientific capabilities. One finding is that a new emphasis on computing advances and instrumentation may weaken basic research in this country. (JN)

Describes an inexpensive and versitile interface which can be readily adapted to many on-line experimental projects in scientific fields by educators who are not computer experts. Hardware and software requirements are noted. (JN)

Highlights findings from National Science Foundation's National Survey of Academic Research Instruments and Instrumentation which examined the amount, condition, and cost of existing equipment systems for 1982 in computer sciences, physical sciences, and engineering. Indicates that one-fourth of the equipment is classified as obsolete by…

Offers suggestions and strategies related to integrating an instrumental approach in high school chemistry. Indicates that the problem-solving process is often clarified using the approach, that the approach improves the quality of the laboratory program, and that it is an effective technique for arousing student interest. (JN)

Describes the quantitative analysis of a gaseous mixture using peak heights and ratios between the peak heights. (MLH)
