As a result of the Corona19 virus, the real-time remote classes were conducted at all universities in Korea in the first semester of 2020. This study analyzed factors that affect the real-time remote class satisfaction and the intention to sustain the remote class of university students through a survey of 420 students from a university in a metropolitan area. Social presence, class quality, learning usefulness, and student interaction perceptions felt by students had positive effects on satisfaction. Physical usefulness, perceived ease of use, professor interaction perceptions, and demographic factors did not have effects. Satisfaction has positive effects on the intention to sustain class. Expectation of learning effect, intimacy between class members, and the quality of the lecture system were three factors that positively affected the satisfaction and the intention to sustain class. It was concluded that professor’s efforts to create a class community in which students feel intimate with each other are necessary for the development of the real-time remote class and if class quality is poor, such as learning contents and learning environment, students will prefer face-to-face class at the university.
