The current research investigated how students' perceptions of their professor's personality, as well as student gender and age, in online and face-to-face courses, predict undergraduate students' course satisfaction. This study was quantitative and non-experimental. Participants included 73 undergraduate students in both online and traditional college course rooms. Data analysis was completed via SPSS using stepwise and multiple linear regressions and Pearson correlations. Findings showed student perception of their professors' extraversion correlated with student course satisfaction at 0.05 level (p < 0.001; F(72) = 2.947). There were no significant results regarding the predictor variables of student gender, course type, or age. Further research is encouraged with interest in these and similar variables, as well as to address current study limitations.
