An experiment tested the efficacy of "discovery learning" in a school setting. Fifty-two bright children ages one to seven were randomly divided into two groups: a discovery learning, non-directed group and a guided learning, teacher-directed group. After both groups had spent eight months using an individualized "talking…

This paper examines the first year activities of an environmental analysis and design project to develop and implement a program that treats the science department of Oak Grove High School, San Jose, California, in an experimental manner. Implicit in this purpose is the development of evaluative and design tools for space users at minimum cost and…

Factors which influence the acquisition of a second language within the framework of the British educational system are examined in this study. An ongoing, 10-year, language experiment (1964-74) involving 18,000 students ranging in age from 8 to 13, concentrates on determining the desirability and practicability of starting modern language…

Describes the functioning of temperature transducers, or thermistors. Discusses the interface connections between thermistors and the game-port of several kinds of microcomputers. Demonstrates how to construct a thermistor probe and suggests several applications of the use of such probes in various scientific experiments. (TW)

Provides some background information on acid deposition. Includes a historical perspective, describes some effects of acid precipitation, and discusses acid rain in the United Kingdom. Contains several experiments that deal with the effects of acid rain on water quality and soil. (TW)

Contains 21 articles ranging from instructional experiments to topical information. Deals with investigation of plant rust diseases, using computers to teach biology, plant roots, a biotechnology curriculum, the corrosion of oxides, electrochemical simulations, the Reimer-Tiemann reaction, the oxidation of aldehydes, and the extraction of iodine…

Reports on a study which compared the effectiveness of microcomputer simulated experiences with that of parallel, hands-on laboratory instruction for teaching the concept of volume displacement to junior high school students. Results indicated that computer simulated experience were as affective as hands-on laboratory experiences. (TW)

Describes an inservice teacher workshop conducted in Pennsylvania which was designed to encourage the introduction of chemistry at the elementary school level. Discusses the organization and content of the workshop, the materials used, and some evaluative information provided by workshop leaders, teachers, and their students. (TW)

Describes the use of a precalibrated stainless steel thermistor, interfaced with an Apple computer, in chemistry experiments. Discusses the advantages of "instant" temperature readings in experiments requiring that readings be taken at certain intervals. Outlines such an experiment which investigates freezing point depressions. (TW)

Discusses the use of two different computer applications to teaching college chemistry. Describes the "electric laboratory notebook" (ELN) courseware and its use in an instrumental analysis course. Provides an overview of the use of commercial spreadsheet programs in the chemistry laboratory. (TW)

Discusses some of the advantages of using overhead projectors to demonstrate chemistry experiments. Provides a list of guidelines and equipment for these types of demonstrations. Describes 21 simple demonstrations that can be done in chemistry classrooms that require minimal equipment and cost. (TW)

Details 26 experiments designed for use in secondary or college science classes. Includes activities for physical and biological sciences. Describes procedures, materials, safety, and analyses appropriate for each. (CW)

Describes an exercise developed at the University of Natal (South Africa) in which students visit a plant which manufactures a variety of lead compounds. Outlines the procedures for the laboratory preparation of lead compounds that students prepare with samples they collected at the plant. (TW)

Reports on the 9th Biennial Conference on Chemical Education sponsored by the American Chemical Society. The conference theme: "Chemistry: Learning, Instructing, Presenting," was addressed by numerous sessions. Highlighted were presentations calling for an increase in process-oriented chemistry teaching, reduction of "science…

Describes a two-week concentrated laboratory course in chemistry offered by Union College (New York) for middle school students. Provides the objectives of the course and a listing of experiments done by the students. Promotes the use of experiential approaches rather than lengthy lectures and discussions. (TW)
