This study investigates the predictors of students' course evaluations and course grades in online team-based learning marketing courses during the COVID-19 pandemic. In Study 1, eighty-three undergraduate students taking a variety of team-based learning marketing courses at two different universities participated in an online survey. Multiple regression analysis results indicate that higher team satisfaction and instructor engagement are associated with higher course evaluations, while conscientiousness and the number of course visits predict course grades. Study 2 with additional sixty-seven students found that loneliness and working hours are associated with lower course grades. The implications of this research are discussed.
