A Comparison of Grades Achieved, Attrition Rates, and Teacher Evaluation in a Traditional General Biology Course Versus a Non-traditional, Audio-tutorial Biology Course.
Belzer, Thomas J.; Conti, Michael R.
In the fall semester of 1972-73, two general biology classes were offered and taught by the same teacher. One class received lecture material in the traditional manner, attending three one-hour lectures each week. The 82 students in this class were designated the control group. The 52 students in the other class, known as the experimental group, received lecture material by working independently at a learning center, using cassette lecture tapes and other audiotutorial materials and equipment. This group also attended a discussion session with the instructor once each week, the session being used for informal discussions only and for administering examinations. Test scores, final grades, and attrition in the control and experimental groups were compared at the end of the semester using statistical techniques. Results of the study showed that: (1) both methods of instruction were equally successful with respect to test scores and final grades; (2) attrition rate was high in both classes--experimental 38 percent and control 31 percent; (3) teacher performance was rated slightly higher by the audiotutorial group; and (4) teacher performance improved slightly with the new method of instruction. Tables provide the study data. The appendix is a copy of the Student Evaluation of Teachers form. (DB)
