The Effects of Instrumentation of Freshman Chemistry Laboratory on Achievement and Interest in Chemistry.
Ledbetter, J. C.
This report presents the procedures, findings, and conclusions of a study designed to determine the effects of instrumentation of freshmen chemistry laboratory on achievement and interest in chemistry. Students in each of 80 matched pairs were randomly assigned to the two types of laboratory. One group used instrumented laboratory techniques and the other used the conventional laboratory techniques. Pretests and posttests of achievement and interest were administered to the subjects. Analysis of the data showed no significant differences between the two groups in (1) ability to recall terms and concepts, (2) ability to apply chemical principles and theories, (3) ability to apply chemical theories and principles quantitatively, (4) knowledge of electrochemistry, and (5) ability to balance oxidation-reduction equations. Findings concerning interest were not considered adequate to give a meaningful interpretation. The investigation concluded that both types of laboratory techniques provide equally well for learning laboratory techniques. (LC)
