Research Problem
TP
CP
SP
CL
CL: cognitive load; CP: cognitive presence; SP: Social presence; TP: teaching presence
4
Research Questions
How well TP, CP and SP predict intrinsic/extraneous / germane CL at the end of a fully online learning experience?
What presence is the best predictor of intrinsic/extraneous/ germane CL at the end of a fully online learning experience: social presence, teaching presence, and cognitive presence?
5
Perceived learningLearner satisfaction
These relate to both each other and the presences
(e.g., Akyol & Garrison, 2008; Arbaugh, 2008; Fredericksen, Pickett, Shea, Pelz and Swan, 2000; Richardson & Swan, 2003; Shea, Li, Swan & Pickett, 2005)
2 important variables
6
Can the presences still predict intrinsic/extraneous/ germane CL significantly at the end of a fully online learning experience after controlling for learner satisfaction and perceived learning?
What presence is the best predictor of intrinsic/ extraneous /germane cognitive load at the end of a fully online learning experience after controlling for learner satisfaction and perceived learning?
7
At the end of a fully online learning experience:
TP + CP + SP CL (Hypothesis 1).
(TP + CP + SP ) – LS CL (Hypothesis 2).
(TP + CP + SP ) – PL CL (Hypothesis 3).
(TP + CP + SP) – (LS + PL) CL
