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…

The impact of enhanced observation or enhanced prediction on scientific reasoning about heat energy and temperature problems was investigated. Instruction was successful in improving prediction and observation skills in the microcomputer-based laboratory environment. (CW)
