The purpose of this study is to explore the essence of motivation and experience in students that participated in self-design seminar as a form of convergence education emerging from University. For this purpose, six engineering students participating in self-design seminar in Korea were selected by snowball sampling method and interviewed in-depth, focusing on their experiences. As a result, participants experiences in self-design seminar were classified into three categories. Category 1 was related to the motivation for participating in the self-design seminar, and it appears that they take part in self-design seminar as ‘invitation’, ‘possibility’, and tool for ‘achieving goals’. Category 2 was an experience that occurred during the course of participating in the self-design semester, learning and designing by ‘learners’ themselves, learning real ‘collaboration’ with the team members and in conflict and resolution, and evaluating the ‘pressure’ on reports. Finally, Category 3 showed the characteristics of ‘learned’, ‘changed’, and ‘trying’ to relate to the knowledge and direction of life learned from reflection of the participants experiences after the participation. The results of this study emphasized that providing opportunities for diverse experiences from middle and high school, sharing the concept and role of professors in convergence education, and the necessity of the convergence education in the university and the innovation by the self reflection.
