Audio-Tutorial Tapes as Aids to College Chemistry Pre-Registrants: A Pilot Study.
Boyd, Vivian; And Others
Between 40% and 50% of Chemistry 103 registrants at the University of Maryland at College Park earn D, F, or W grades. Registrants for Chemistry 103 were randomly selected to participate in a pre-course refresher consisting of listening to as many as seven audio-tutorial tapes on the basic concepts and calculations of chemistry. Records were kept of who listened to tapes and how many tapes each student requested. Chemistry 103 final grades were examined for three groups: (1) students (N=13) who listened to at least one tape (users); (2) students (N=34) who were asked to participate but who chose not to listen to tapes (nonusers); and (3) a nontreatment comparison group (N=49). The results revealed that 64% of users earned a final grade of A or B or C while only 45% of nonusers and comparisons received at least a C grade; the difference was not statistically significant. There were no differences among groups in terms of academic persistence. These findings support further study of the use of audio-tutorial tapes on the basic concepts of chemistry prior to taking the chemistry course as an effective way to help students do well in chemistry. The fact that students who chose to use the tapes also earned higher grades in other courses, however, suggests that motivation and academic ability may account for performance differences in Chemistry 103.
