A Test of Effectiveness of Courseware in a College Biology Class
At Colorado State University we designed an experiment wherein approximately half of a class of 184 students in a semester, first-year biology class was placed in a traditional hands-on, experiential laboratory for two hours per week and the other half was placed in a facility with Macintosh computers to view courseware for the same time period. Computer-presented tutorial and simulation of biology laboratory concepts proved to be as good as or better than traditional approaches in increasing student academic performance. The courseware-using group performed better ( p < 0.05) than the traditional laboratory group in overall lecture examination scores, when the pretest scores of the two groups were factored in. Curiously, attitudes in regard to the use of the courseware showed a striking negative trend in this experiment.
