Using data collected from a sample of 52 engineering faculty members at the University of Puerto Rico at Mayaguez, we explore the relative impact of faculty members' personal characteristics, computer self-efficacy, and attitudes toward the Internet on integration of electronic communication in teaching. The study reveals that computer self-efficacy in using the WWW is the only predictor of integration of electronic communication in teaching courses. Our results also show that computer self-efficacy in using the WWW was related to attitudes toward the Internet, age, and gender. The results suggest that these variables need to be considered when planning training programs or differential staffing for reconciling faculty and their integration of electronic communication in teaching courses.
