This study explores the extent to which subjective norm beliefs of online learners shape perceptions of ease-of-use and usefulness for the use of course delivery systems. Subjective norm beliefs represent the influence that instructors, mentors, and peers have on students to use the course delivery system. The results show that instructor and mentor influences are significant contributors to students' perceived usefulness of the course delivery system. However, only mentor influence is significant to students' perceived ease-of-use of the learning system. These results indicate the importance of the instructors' roles in shaping impressions of the value of using the course delivery systems and the potential underutilization of peer influence to shape behavior in online courses.
