The Effect of the Laboratory on the College Students' Understanding and Knowledge of Physical Science, Final Report.
Crawford, Eugene; Backhus, DeWayne
This paper presents the procedures, results and conclusions of a study designed to determine whether three different methodological approaches to the laboratory for a general education physical science course would lead to the same behavioral outcomes. Students enrolled in the physical science course were randomized into one of three laboratory treatment groups; a highly structured scheduled lab, an audio-tutorial type free lab, and a loosely structured home lab. Behavioral changes were assessed through instructor-written unit tests and the Test On Understanding Science (TOUS). Data were obtained for 140 students during the first experimental period, and for 195 students during the second experimental period. The results indicated that (1) no significant differences existed among the lab groups in terms of their cognitive knowledge of science, (2) for the first experimental period, no significant differences existed among the groups with respect to their understanding of science as measured by TOUS, (3) for the second experimental period, significant differences existed among the groups on TOUS scores, and (4) the free lab and home lab groups scored significantly higher on TOUS than the scheduled lab groups.
