Research indicates that the educational effectiveness of Microcomputer-Based Laboratories (MBL) may be due to the real time nature of the experience. This article describes a study where kinesthetic feedback was completely removed by giving students only visual replications of a motion situation. If simultaneity of perception is the important…

Describes the implementation of a new microcomputer-based laboratory (MBL) curriculum focusing on motion into a physical science course for preservice elementary teachers at Indiana University. Reports the results of tests administered to teachers before and after the motions unit. Discusses implications for instruction. (LZ)

Graphs of objects in motion are frequently used in introductory high school or college physics courses since they offer a valuable alternative to verbal and algebraic descriptions by offering students another way of manipulating the developing concepts. If graphs are to be a valuable tool for students, then the level of the students' graphing…
