Abstract
Previous research has suggested that the frequency of instructor participation in online discussion forums can affect student participation and subsequently their learning results in online courses. However , the different approaches of instructor participation and their effects have not been well studied, particularly in MOOCs of very large class sizes. This research investigates how instructor participation via posting vs. replying in online discussion forums affects student participation in MOOCs. Our results show that instructors mainly participate through replying rather than posting. However , instructor posting is more effective than instructor replying on enhancing student participation, and this advantage of instructor posting over replying increases with class size. Class size negatively moderates the positive effect of instructor replying, but not that of instructor posting. These findings implicate the necessity of a well-planned participation strategy for instructors to engage in MOOC discussion forums.
