The use and evaluation of videodiscs in the chemistry laboratory

Abstract

Description of videodisc technology and an evaluation of its application to the classroom.

Images imagination, and chemical reality

“…This is illustrated in Figure I, which shows the effect of replacing a line drawing of a beaker (6) with a digitized photograph in a typical CAI program. The use of a videodisc player connected to a microcomputer makes it possible to select randomly any of 54,000 still video images or to combine them to give up to 30 minutes of full motion video (7,8). These TV pictures can be mixed with computer-generated text and graphics on one screen, either by an overlay card in the computer, such as the Micro-Key System1 or by a special monitor, such as the IBM InfoWindow (9).…”

“…Figure7. Students learn about the solubility of various metal salts by asking the computer to show them the result of mixing various solutions.…”

Inquiry Learning with Videodiscs and Computers: An Innovative Teaching Method for Horticulture Courses

“…d) In addition to vast storage capacity, videodiscs provide multiple ways of accessing information, including opportunities for repetitious practice, multiple examples, different problem types, and simulated experiences (Gindele and Gindele, 1984;Smith and Jones, 1986;Hannaway et al, 1988). e) Videodiscs can add interest, and stimulate enthusiasm and motivation due to the intrinsic appeal of visual images, stimulations, feedback, individualized instruction, and games (Malone, 1981;Russell et al, 1985).…”

Changing views of NMR: automated high-resolution NMR with a sample changer

“…New educational approaches such as computer simulation (5) or interactive videodisks (6,7) offer an attractive, less expensive option to fundamental NMR education. For example, an NMR interactive videodisk project that teaches fundamentals has recently been described (7).…”
