This paper describes a trial educational program that combined the "Jigsaw method" with the "PBL (Problem Based Learning)". In PBL program in Ibaraki KOSEN, there are some problem caused by a difference in skill level between "Robot club students" and "Non-robot club students". I tried to solve these problems, so I combined the Jigsaw method with the ordinary PBL and gave some small lectures to "Non-robot club students" based on Jigsaw method. As a result, 4 groups completely succeed in assigned problem about a line trace robot.
