This study concerns the design and development of online instruction and specifically targets interaction and communication between online learners. Facilitating appropriate and meaningful interactions in designing instruction is a major goal for anyone developing a course, especially an online class. The data for this study came from the online courses offered at one of the major Rocky Mountain University. The research subjects and courses were taken from the College of Education, College of Business, College of Arts and Sciences and College of Health Sciences. The findings of this study suggest that the interactivity in an online class depends on the discipline it belongs to and hence, future research must focus on explaining the overall interactions within a discipline.
