The text seeks to help students reach, through about 90 hours of class instruction, to acquire a level of competency necessary to repair a piece of laboratory equipment or construct a simple piece of equipment. Tools are introduced as needed in each of three sections of the text: (1) woodwork and metalworking; (2) electronic circuits; and (3)…

Investigated were teacher-pupil and pupil-pupil relationships in the context of elementary science activities, of which the characteristic feature was the predominance of small group work by pupils without continuous teacher direction. Two pairs of pupils from each of ten classes were recorded for a single class session using two independently…

The complexity of today's research laboratories requires a completely controllable environmental surrounding. Research facilities require carefully controlled temperatures, relative humidity, and moisture, and must be free of interference from air-borne sound, mechanical vibrations, and electrical sources. Also desirable are special power…

This presentation of suggested layouts and specifications has been prepared to be of service to school boards, architects, teachers, and administrators who are planning new schools or making renovations to existing structures. The recommendations cover many of the facilities that have been observed in schools throughout the province, and which…

Discusses the need to develop laboratory practical examinations in chemistry which attempt to measure students higher order thinking skills and conceptual understanding rather than simply their laboratory skills. Examples of examination questions being used in general chemistry laboratory courses at the State University of New York at Cortland are…

Reports on the session at the New England Association of Chemistry Teachers meeting on chemistry laboratories in March 1987. Speakers included Leonard K. Nash and Audrey Champagne on values and goals; Howard Ende on regulation; Stanley Smith and Jerry Bell on the uses of computers; and Miles Pickering on the human dimension. (CW)

Describes a molar volume-molar mass experiment for use in general chemistry laboratories. Gives background technical information, procedures for the titration of aqueous hydrogen peroxide with standard potassium permanganate and catalytic decomposition of hydrogen peroxide to produce oxygen, and a discussion of the results obtained in three…

SCIENS is a Middlebury College (Vermont) program designed to excite minority student interest in the natural sciences and to provide students with training and research experiences. The program, encompassing three summers, involves core instruction for high-potential 11th-grade students, summer research in college laboratories, and internships in…

Expresses concern over recent actions by coalitions of neighborhood activists and animal rightists in the San Francisco area that are seeking to block new biology laboratories. Argues that costly delays and disurption of research could result. (TW)

This description of microcomputer-based laboratories (MBL) for science focuses on experiments with a motion detector by non-science majors at Tufts University. Exercises had been used previously with sixth grade middle school students, indicting the effectiveness of MBL for students with a wide range of abilities. (Author/LRW)

Recounts the problems of a high school chemistry program in safely storing and disposing of chemicals. Describes the school's new system of inventorying and dating all chemicals, using warning stickers, isolating certain hazardous substances, and cataloging references to the use of each chemical and its container. (TW)

Addresses the history and philosophy of accident prevention in chemistry laboratories. Presents the results of a statewide survey done in Colorado designed to investigate the etiology of academic chemistry laboratory accidents in institutions of higher education. Patterns of accident characteristics identified by the student are discussed. (TW)

Describes the construction of a low-cost (about $70.00) alternative to the commercial fraction collector. Outlines the separate parts of the collector and provides a schematic of electronic circuitry of the instrument. Lists special items required for the development of this project. (TW)

Determined that an instructional unit on laboratory safety could increase student safety knowledge and reduce the number of unsafe behaviors. A list of unsafe behaviors which were observed with the 333 students is included. A recommendation that positive attitudes toward safety be developed is given. (DH)

Student-centered approach of scoring the concept maps consisted of three elements namely symbol system, individual portfolio and scoring scheme. We scored student-constructed concept maps based on 5 concept map criteria: validity of concepts, adequacy of propositions, significance of cross-links, relevancy of examples, and interconnectedness. With…
