Effects of Audio-Visual Supported Instruction and Instruction without Audio-Visual Support on Student Grade Point Average. Learning Theory and Applications.
A study examined the effect of audiovisual-supported instruction on student grade point average. Two groups of students in economics classes taught by the same instructor served as the sample population for the study. The first group, consisting of 36 students, received four 1-hour lectures each week. The second group, consisting of 32 students, received minimal lecture material and heavy exposure to audiovisual media in the form of graphs, cassette lecture tapes, films, and other related materials. The grade point averages, pre- and posttest scores, and attrition rates of students in the experimental and control groups were compared. This comparison revealed that both methods of instruction were equally successful with respect to grade point average. Attrition rates were low in both classes--8.5 percent in the experimental group and 10 percent in the control group. Results clearly indicate that audio-visual aided instruction is effective; however, future studies and experimentation in the area of instructional methods will be required. (Detailed breakdowns of the study data are appended. (Author/MN)
