An examination was undertaken of a programed-study procedure employing behavior theory concepts in teaching undergraduate course material. Study units were constructed, containing a specific reading assignment and study guide questions. When the student felt himself to be ready, he was given a test. Progress through the course was contingent upon satisfactory performance. This procedure was used in 13 courses, enrolling 850 undergraduate students and taught by six faculty members over a time period of 18 months. The effects of the procedure were assessed in terms of (1) performance on hourly exams, (2) degree of participation in the program, and (3) student attitude toward programed study. The project involved (1) the refinement of programed study technique, and (2) the testing of the procedure's range of usefulness. The results of the investigation indicated that the programed-study procedure produced significantly better performance in all courses taught within the Department of Psychology and in about a third of the non-psychology courses. Student attitude was generally favorable toward the programed-study procedures. The appendices include the questionnaire used in assessing student opinion and an outline of the development of a programed course. (Author/MF)
