摘要：More and more courses are no longer based on the examination results to evaluate the effect. As the main participants, students are paid more attention to, especially their mental feelings. This paper explores the mediating effect of self-efficacy and the mutual relationship between personality traits and course subjective well-being. A questionnaire was conducted among 310 students in the course “comprehensive experiment of management”, correlation and regression methods were used to investigate the relationship between variables. The course participation role, gender, family origin and subjective character identification all significantly affect the course subjective well-being. Openness has no significant correlation with course well-being, neuroticism has a negative correlation, and extroversion, agreeableness, conscientiousness and self-efficacy have a positive correlation. Self-efficacy has a complete mediating effect between neuroticism and course well-being and a partial mediating effect between extraversion, agreeableness, conscientiousness and course well- being. The course subjective well-being of students is influenced not only by their innate personality traits but also by their acquired self-efficacy.
