How much time does it take to teach an online course? Does teaching online take more or less time than teaching face-to-face? Instructors, department chairs, deans, and program administrators have long believed that teaching online is more time-consuming than teaching face-to-face. Many research studies and practitioner articles indicate instructor time commitment as a major inhibitor to developing and teaching online courses. However, while they identify the issue and provide possible solutions, they do not empirically measure actual time commitments or instructor perceptions when comparing online to face-to-face delivery and when comparing multiple iterations of delivery. The results of this study show distinct differences in developing online courses relative to developing face-to-face courses and distinct differences in teaching online courses relative to teaching face-to-face courses. The data from this study can be used by instructors, administrators, and instructional designers to create higher quality course development processes, training processes, and overall communication.
