The purpose of this study is to explore the structural relationship among satisfaction of human relations, interaction with the faculty, cooperative learning, and institutional commitment of university students. In particular, the mediating effect of faculty-student interaction and cooperative learning in the relationship between satisfaction of human relations and institution commitment was examined. Data from 83,773 students attending 113 universities participating in 2019 K-NSSE were analyzed, and a structural equation model was employed. According to the results, the quality of human relationships perceived by students had a positive effect on interaction with professors, cooperative learning, and institutional commitment, respectively. In addition, the greater positive perception on the quality of human relations led to more interactions with professors and cooperative learning, which in turn had a positive effect on students institutional commitment. The results suggest that human environments formed by campus members’ relations can be an important factor that positively influences student s academic and emotional growth and development. Therefore, universities need to make efforts to establish a positive human environments, that is, building university community, in order to promote learning and growth of students.
