Microcomputer-based laboratories (MBLs) refer to a laboratory where a microcomputer gathers and displays data directly from the environment. Program listings for a response timer (using game paddles) to illustrate the nature of MBLs are presented. (JN)

Describes a program in which senior engineering students are given the opportunity to design, make, and test apparatus intended for an upper-level teaching laboratory. Discusses such projects as a vapor compressor test stand with refrigerant mass flow measurement, a double-walled concentric annular heat pipe, and a vacuum filling station. (TW)

Discusses the use of microcomputers in science education: (1) computer-assisted instruction; (2) testing; (3) data processing; (4) simulation; (5) teacher assistance; and (6) data collection. Gives educational applications of microcomputer-based laboratories, pointing out advantages and disadvantages. Outlines current drawbacks and makes…

Pinpoints common areas of neglect in considering science safety. Familiar hazards are discussed, with special consideration of improper chemical storage, old and unlabeled chemicals, and faulty circuits and equipment. An appendix lists basic safety rules and presents a checklist for general laboratory safety. (CS)

Presented is an inspection form developed for use by college students to perform laboratory safety inspections. The form lists and classifies chemicals and is used to locate such physical facilities as: fume hoods, eye-wash fountains, deluge showers, and flammable storage cabinets. (BT)

Civil lawsuits brought for injuries to students are a source of growing concern for teachers, and especially for science teachers. This paper outlines some basic principles by which science teachers may protect themselves from lawsuits, before and during the time that students are engaged in experiments or lab work. Courts in this country have…

Examines the influence of both teacher and pupil use of science equipment on Nigerian students' attitudes to science. Test results from students in 36 secondary schools indicated that schools making considerable use of science equipment, particularly with girls, were associated with more positive attitudes to many aspects of science.
