Online courses can be interactive or completely dead, all depending upon the instructor. One factor is true for all online courses, however. They are all much more reading intensive than the classroom setting. There is more work because all learning must be demonstrated through writing and assignments. There is basically no interaction with peers when taking an online class. I took two online classes this past semester and one was great, the other was terrible. The great class was an English class. We had weekly readings and essays and our instructor gave excellent feedback. He made sure to communicate how you could improve your papers and responded very quickly to emails. The other class I took was history. We also had weekly quizzes, but the instructor never communicated to one student in particular. I never received any feedback. I emailed her with concerns about some of my quizzes, and she never emailed back. I had to find out her office hours first and go to her office before she would help me. Overall, the quality of online classes are very subjective based on which instructor you get.
