Instructor presence is required for social presence to occur, and social presence is necessary for cognitive presence (Akyol & Garrison, 2008; Garrison, et al., 2001; Shea & Bidjerano, 2009). Furthermore, Shea & Bidjerano (2009) purport that “teaching presence predicts variance in cognitive presences directly” (p. 545). As an example, they found that when the instructor focused and participated in discussion, teaching presence correlated to higher cognitive presence.
Instructor presence leads to social presence which leads to cognitive presence.
