The Educational Development Questionnaire (EDQ), a 60-question rating scale, was designed to measure the teaching behavior of adult educators in terms of Malcolm Knowles' descriptions of andragogical (self-directed) and pedagogical learning processes. The EDQ was first used during 1978 winter classes by 961 students who rated the teaching behavior of 74 randomly selected instructors at four North Carolina two-year colleges. Factor analysis yielded seven factors which accounted for 25% of the total variance: student involvement, instructor control, distrust and detachment of the instructor, professionalism, counseling, individual inattention, and organization. All factors with the exception of student involvement had been identified in previous adult education research as dimensions of student-perceived teaching behavior. Identification of aspects of student involvement in the design and operation of educational programs as a separate factor is particularly significant, since this is a primary difference in Knowles' concepts of andragogy and pedagogy. A second phase of the analysis determined that students perceived more controlling behaviors or conditions in curriculum classes than in continuing education classes. Further research using the EDQ or a modified questionnaire including student involvement items and a broader sample of educators may lead to a clearer difference between teaching behaviors of the two groups. The EDQ may also help improve adult teacher self evaluation. (MEK)
