This description of the use of "probeware," i.e., hardware which connects to a microcomputer and works with the software to measure factors such as temperature, light, or motion in science laboratory experiments, uses as an example an experiment which would involve the measurement of pendulum motion using the "Precision Timer II" software program. Strategies for classroom teachers to become involved with probeware are suggested, additional available probeware is discussed, and information on the providers of workshops and training programs is provided. The 19 reference items listed include the names and addresses of software distributors and organizations providing training, as well as journal articles and books. (EW)
