Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

This researcher investigated two problems: (1) the accuracy and validity of instruments which measure Piagetian levels of thought; and (2) the need for more detailed models of concrete and formal operational structures, both as they develop and consolidate, and in their most highly developed state. Several tasks such as the Piagetian correlations…

Discusses the development, field testing, and validation of an instrument designed to assess secondary school students' understanding of the nature of scientific knowledge. (GA)

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)

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)

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)

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.
