We are developing an education method to raise ability for design of the product depending on social needs. To that end, it is useful that students cooperatively experience the process consisting of specifications development, designs, productions, and evaluations. Therefore we carried out the design education of the complex problem by the collaboration work through the design production of the small vehicle. Specifically, the student carries out design production of simple vehicle at third grade. Furthermore, they perform high level design production in graduation study of fifth grade. As a result, at third grade, all groups organized for training were able to manufacture vehicles and these were able to run carrying a person. Three people among them jointly designed and produced a vehicle at fifth grade.
