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…

Describes a study of high school students that investigated the use of microcomputers to teach principles relating to the design and interpretation of graphs. Results related to student achievement, higher order thinking skills, and behavioral protocols are discussed. A sample assignment sheet and test questions are appended. (66 references) (LRW)
