The educational support programs offered at the Niko Niko Room of the Center for School Education and Research of Hiroshima University enable university students to support school children with their studies, especially arithmetic. Effects of the educational support programs of 2014 on university students were examined in this study. Sixty-two students answered questionnaires before and after the programs. Of the 62 students, 24 students did the actual study support and 38 students observed the study support done by other students. Students who did the actual teaching were taught and supervised by supervisors. All students participated in case review sessions where the group reviewed each case. Through their participation in the programs, both the students who did the actual support and who did the observations formed “assessment” and “teaching skill” abilities. Students were especially able to better their ability in understanding where the school children were troubled, and correcting the wrong thinking process the school children had. Overall, university students were satisfied with the educational support program where they were able to interact with the school children, and to experience actual teaching.
