Research Problem Rationale/Significance/Why? Conceptual Frameworks Data Collection & Analysis Validity Limitations 2
Research Problem TP CP SP CL CL: cognitive load; CP: cognitive presence; SP: Social presence; TP: teaching presence 3
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? 4
Perceived learning Learner 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 5
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? 6
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 Hypotheses 7
WHY? 8
The CoI Framework 9
CL Theory 10
Working Memory 11
Data Collection Correlational Prediction Design Context: A fully online LDT program + 4 elective courses Purposive sampling Participants: off-campus professionals Instrumentation: o The CL survey o The CoI survey o Learning satisfaction & Perceived Learning Survey o Demographics Survey Participants Instructors 12
Data Analysis Differences between the courses/sections: 2-way ANOVAS Research Questions: Standard + Hierarchical Regression o Bonferroni adjustment p =.016 o Assumptions: No outliers (IVs & DVs) No Multicollinearity and Singularity Normality, Linearity, & Homoscedasticity Independence of errors 13
What if an assumption is violated? 14
Multicollinearity 15 a p <.01(2-tailed) Kozan & Richardson (2014) Presence Type Teaching Presence Social Presence Cognitive Presence Teaching Presence a / a /.730 a Social Presence a /.563 a Cognitive Presence -
Validity 16 Controlling for important variables (LS & PL) Is this a real CoI? Temporal precedence History Effect Low Temporal validity CROSS VALIDATION
Limitations Purposive sampling = similar programs only Low ecological validity Elective courses Subjective rating scales Correlational not cause-and-effect Fixed order of the surveys 17
