Abstract
Problem-based learning program for mechanical design provides to improve engineering sense of students. In this program, a wide range of theoretical and practical problems related to manufacturing are prepared for the students. Several approaches and solutions to the problems are proposed by the students, or suggested by their supervisors. A lot of discussions and considerations are repeated in this procedure as just-in-time education. The procedure requires a huge amount of time and effort to the supervisors, but it will give good opportunity and experience to the students for improving their engineering sense.
