Abstract
A new obligatory subject, Computer Programming IV, is organized in the Department of Informatics, Faculty of Engineering, Yamagata University. The purposes of the subject are as follows: (1) Attachment to each laboratory for bachelor thesis was usually at the initial stage of the student's fourth academic year. This subject actually moves up the attachment because students are tentatively attached to a laboratory for this subject. The interval to complete their bachelor thesis is extended by half a year. (2) In each laboratory, students cooperate with each other to complete their project. The project becomes capstone design which JABEE (Japan Accreditation Board for Engineering Education) is recently emphasizing. We not only explain the introduction of this subject, but also report some case studies.
