The purpose of this paper is to study the self-directed learning experiences of mature students in liberal arts courses at universities. In this study, the above mentioned experiences were analyzed through focus group interviews, as a qualitative research method, targeting five mature students enrolled a B liberal arts course at university. The results of this study are as follows. First, at the time of entering university, the research showed that mature students attempted learning at university with high school friends, attempted learning at university immediately after completing high school courses, attempted learning at university as a driving force for life, and attempted learning at university for the purpose of acquiring qualifications. Second, at the time of their application for liberal arts courses, the mature students chose liberal arts courses based on the department's collective timetable and the liberal arts policy in relation to the distance education provided by the university. Third, during the liberal arts courses, the mature students learned with classmates through competition and cooperation, through effort of repetition, through joyful participation, and through empathy understanding. Fourth, at the time of evaluation of liberal arts courses, the mature students grew through a belief in themselves, through the realization of the value of learning, and through their sastifactions with life as it pertained to their communication with their families. Fifth, in the preparation period for the next semester of university, the mature students challenged themselves by auditing other university classes and by engaging in extracurricular activities. The suggestions based on the results of this study are as follows. First, it is necessary to overcome the restrictiveness and rigidity of the existing university liberal arts courses by linking them with lifelong education. Second, it is necessary to provide continuous learning opportunities for mature students through advanced programs and in-depth programs in liberal arts courses. Third, it is necessary to promote learning motivation for mature students by strengthening the relevance of university courses with the real lives of their learners, as well by strengthening the interactions of students in liberal arts courses. Fourth, it is necessary to build a learning environment in which mature students can learn autonomously.
