In past studies by the author regarding university students' learning and development, mainly three results were found; first, there was too little time for out-of-class studies regardless of the recent trend of hard studies in the classrooms. Second, nevertheless, those who studied hard outside classes felt they were developing; and third, the particular ways they spent outside classes were effective in acquiring new knowledge and skills. Through these results, this study examined university students' learning and development from a college life perspective. Past results implied that, if you would like to examine student learning and development, you should approach not only classroom studies but out-of-class studies and extra-curricular activities, too; that is, students' whole college lives. The survey was administered nationwide in November 2007. A total of 2,013 students participated (988 first year and 1,025 third year students). The analyses were done by using four student types (Type 1 to Type 4) which were determined using cluster analysis with scores of college lives. The main result was that Type 3 significantly felt more of their development than other types through many different activities, including in-class and out-of-class studies. Type 4 students, who enjoyed their college lives without being much involved with out-of-class studies, were as satisfied with their college lives as Type 3 students. However, Type 3 students scored significantly higher than Type 4 students on future perspectives, acquisition of knowledge and skills, etc. I concluded that well-balanced activities including studies were important for student learning and development.
