Although several studies of the student-perceived teaching behavior of postsecondary educators have recognized student participation as a dimension of teacher behavior, few, if any, of these studies specifically describe the instructor's involvement of students in the design and operation of an educational program. The Educational Description Questionnaire, which contains items describing student involvement behaviors, was developed for this study to test the hypothesis that students perceive these behaviors as a dimension of teacher behavior. It was administered to 961 students by seventy-four instructors in four two-year colleges. Factor analysis of each of the sixty items on the questionnaires identified student-involvement behavior as a significant factor. Further research on the student-perceived behavior of postsecondary educators should include items that describe student involvement behaviors.Several studies have used survey questionnaires and factor analysis to identify dimensions of student-perceived teaching behavior among postsecondary educators. Studies by Gibb (5), Isaacson (7), Solomon (16), Deshpande (4), and Croft and Cotter (3) have identified from four to fourteen dimensions of student-perceived teaching behavior, and at least one factor identified by each of these studies contained items describing the student's participation in the learning situation. Gibb called this factor Friendly Democratic Behavior; Isaacson called it the Group Interaction dimension ; Solomon called it Lecturing versus Encouragement of Broad, Expressive Student Participation; Deshpande called it the Interaction factor; and Croft and Cotter called it Class Participation. The items in each of these factors describe the amount of student discussion, the amount of student freedom to do things in new ways, and the amount of student freedom to express opinions.Malcolm Knowles has indicated, however, that some instructors may use teaching behaviors that are designed to increase student involvement in the learning process beyond that which is recognized by the preceding studies. In three books and several articles, Knowles (8, 9,10,11,12, 13) describes a set of teaching practices that he calls &dquo;andragogy&dquo; -a process for helping students to become self-directed learners. The andragogical educator, according to Knowles, involves students in a process consisting of the follow-MICHAEL A. KERWIN is an Instructor
