In a first year seminar of mechanical engineering program, 71 students handcrafted 5 “Stirling engines for DIY beginners (SE4DIYB)”, and all of the 5 SE4DIYBs carried out non load operation with heat using steam. It had taken from 7.5 to 9 hours. In SE4DIYB, both heat exchangers of hot end and cold end are made of aluminum sheet pans which are called hyoujun bat-5-gou in Japan. Students carried out all of processes in the handcraft of SE4DIYB, except for gluing pattern papers on a polyvinyl chloride sheet. Explanation of SE4DIYB handcraft was done by the pattern papers printed by MS-Word and a document. Stuff did not explain how to make SE4DIYB. Assembly of SE4DIYB was assumed to be taken 3 hours. Non-cognitive skills effected on the amount of time spent on handcraft of SE4DIYB. Not all the students had read those explanations. And, students did not communicate openly and frequently.
