Mastering Subject Matter Through Audio-Tutorial Techniques for Teaching Biology. Final Report.
Sparks, Phillip D.
College biology students, using an audio-tutorial format, participated in a study in which instructional time and quality were structured to accommodate for differences in students' abilities to attain their potential (mastery strategy). Students in the experimental group who failed to achieve 80 percent on an evaluative checktest for a subunit were required to participate in some corrective measure: repeating the study of the subunit, studying the objectives, reading a portion of a manuscript, conferring with the instructor, or some combination of these. The control group was not required to achieve mastery on any of the subunits. At intervals during the course both groups were examined and the composite score of the exams, The Biology Achievement Test, was compared for the groups. Both groups had been pretested, with analysis of covariance used to account for initial differences in the two groups. The achievement of the experimental group significantly exceeded that of the control. Although students in the experimental group spent significantly more time in course work, primarily in the laboratory, than did those in the control group, they also exhibited a more positive reaction to the course.
