Implementation of PBL (Project Based Learning) is important for engineering education. However, PBL programs have the problem that it is difficult for teachers to manage class and to set the standard for student evaluation. Furthermore, students’ problem-solving conclusions may be weak and may not have educational effects. To solve these problems, project themes were limited to one set by the company. Furthermore, in order to improve the level of problem solving for students, the project aims to design products as an outcome of problem solving. After the project, about 60% to 90% of the students felt that the 12 abilities defined by the Ministry of Economy, Trade and Industry in the “Fundamental Competencies for Working Persons” improved their abilities. This paper describes the development project of paper toys and paper crafts using special stickers that can be freely attached and removed as many times as possible, by 4th grade students of Kanazawa International College of Technology, and its educational effects.
