Suggests an apparatus to improve the measurement of the mechanical equivalent of heat. Describes the materials needed to construct the apparatus; the methodology of an experiment to measure the heat gained by lead shot falling through a distance of 100 meters; and the calculations made to register that gain. (MDH)

Presents one way, using simple materials available in hardware stores, to obtain accurate measurements of gravity acceleration in student laboratories. Analyzes a time-of-flight measuring scheme and discusses the experimental arrangements to make the measurements. (MDH)

Scoring guidelines are given for four forms of the practical skills tests of the Second International Association for the Evaluation of Educational Improvement Science Study conducted in the following countries in the 1980s: (1) Hungary; (2) Japan; (3) Korea; (4) Singapore; (5) Israel; and (6) the United States. (SLD)

Develops the idea of fractals through a laboratory activity that calculates the fractal dimension of ordinary white bread. Extends use of the fractal dimension to compare other complex structures as other breads and sponges. (MDH)

The Milwaukee School of Engineering (MSOE) in Wisconsin has entered into a partnership with industry to fund continuous upgrading and expansion of its laboratories. The program has succeeded because of industry's need to hire work-ready graduates who have experience with the companies and with the latest technology. (MSE)

Attitudes and policy developments in the United States on use of animals in education are reviewed, and the legislative position outlined. The influence of science competitions and national teacher associations on practice is discussed. The common invasive experimentation on sentient animals by young and inexperienced students is provoking…

Describes the Knowledge Gateway Project at Wenatchee (Washington) High School, which combines computer technology with a problem-solving approach to teach communication and information processing skills to at-risk students. Networked Macintosh workstations are described; and the use of electronic mail to communicate both within a local area…

The debate on the educational value of dissection versus the value of animal life is examined. Interactive videodisc (IVD) technology is described in light of its potential for laboratory simulations. The design of the IVD-based dissection simulation, The Interactive Frog Dissection, is presented. (KR)

Description and review of recently introduced computer software focuses on word processing in non-Roman character sets for the MacIntosh, courseware developments using recordable CD-ROM drive, desktop video and graphics equipment, and a language lab management package. (CNP)

Criterion-related validities of 2 laboratory practitioner certification examinations for medical technologists (MTs) and medical laboratory technicians (MLTs) were assessed for 81 MT and 70 MLT examinees. Validity coefficients are presented for both measures. Overall, summative ratings yielded stronger validity coefficients than ratings based on…

Described is a program in which students learn about spectroscopy and instrumentation to solve a chemical forensic mystery. Infrared and nuclear magnetic resonance (NMR) spectroscopy, refractometry, and chromatographic techniques were used. An example of a mystery case is included. (KR)

Listed are 75 computer software programs which are available for use in teaching physiology at the high school and college level. Included is a brief description of each and an address for obtaining additional information. (CW)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Detailed are the construction of a demonstration car, apparatus and procedures used in the demonstration, and the analysis of the effects of car braking. The cases of rear-wheel and front-wheel braking are considered. (CW)

This study used the Science Laboratory Environment Inventory and skill and attitude measures to investigate associations between student outcomes and classroom environment for high school chemistry students. The nature of the classroom environment accounted for appreciable proportions of variance in both cognitive and affective outcomes beyond…
