A study was conducted at Phillips County Community College to examine part-time students' and adjunct faculty members' perceptions of effective instructional behaviors and strategies. A teaching effectiveness survey was distributed to a random sample of 225 part-time students enrolled in spring 1984 and to 54 adjunct faculty members, asking them to specify which of 48 instructional behaviors/strategies were most effective in helping students learn and to indicate the skill areas in which part-time faculty needed staff development opportunities. Study findings, based on responses from 43% of the students and 76% of the faculty, revealed: (1) there was a high degree of similarity between faculty and student perceptions of effective instructional behaviors/strategies; (2) creating an atmosphere of acceptance, treating students fairly, and including recent developments in the field were the top three strategies/behaviors for students and were within the top eight for faculty; and (3) students and faculty generally disagreed on the staff development needs of part-time instructors, with students rating providing up-to-date developments in the field, advising students about career opportunities, and encouraging original thinking most highly and faculty members rating course planning; providing printed handouts; and using films, tapes, and slides most highly. The survey instrument and recommendations for staff development planning are included. (HB)
