“…Others question whether the instructor should facilitate online discussions, because they feel it may be too time-consuming to oversee discussions properly and may unintentionally develop discussions that center on the instructor's comments (Correia & Baran, 2010;Light, Nesbitt, Light, & White, 2000). As a result, peer facilitation-in which students collaboratively control the discussions in an OLE (Bull, Greer, McCalla, & Kettel, 2001;Hew, 2015)-was proposed because students may increase their cognitive engagement when they recognize that their instructor is less engaged (Belcher, Hall, Kelley, & Pressey, 2014), and they may feel more comfortable asking for help, discussing their experiences, challenging and negotiating ideas, and sharing their views in a peer-facilitated online discussion rather than an instructor-led one (Bull, Greer, McCalla, & Kettel, 2001). According to Clarke and Bartholomew (2014), research on the role of the instructor has been inconsistent; they argue that discussions should be moderated, but how much moderation is needed from the instructor and the extent to which the instructor's participation matters is unclear.…”
