This study employed a quantitative research design to examine the predictive relationships between social presence and course retention as well as final grade in community college online courses. Social presence is defined as the degree of one's feeling, perception and reaction to another intellectual entity in the online environment. Course final grades included A, B. C, D, F, I, or W. Course retention was defined as successfully completed a course with an A to C grade. The results of the binary and ordinal logistic regression analyses suggest that social presence is a significant predictor of course retention and final grade in the community college online environment. Two effective interventions are recommended: establishing integrated social and learning communities; and building effective blended learning programs. (Contains 8 tables.)
