Research Report on College Level Physical Science for Non-Majors.
Schellenberg, John P.
This research report focuses on an experimental study comparing two laboratory approaches to a college level physical science course for non-majors. An approach using contemporary topics was compared to an approach using standard topics. The three dependent variables were achievement of subject content, scientific attitude, and understanding the nature of science. The data analysis showed no significant difference between treatments. The study used design features intended to control possible teacher effect. Of these, a treatment monitoring instrument used to measure congruence between intended and actual treatment proved very useful. It showed on a second trial of the experiment that one of the laboratory instructors did not follow the intended treatment. This was valuable in the analysis of data for that trial. It is strongly recommended that such monitoring techniques be included in this type of experimental design. (Author/DS)
