In this study, middle school students, from 7th to 9th grade, who already completed section of the 'force and motion' are targets. Based on the survey of the students following conclusions are obtained using by 'before and after' of repetition learning. First, through the pre-test results and measured the degree of concept, repetition learning was found to be effective. Second, through the post-survey after repetition learning science concerning was increased rather than before learning. Students who do not like physics appear to be better awareness of interests and improved self-confidence. Third, to achieve a higher learning effect, 'force and motion' section has to be studied through 7th and 8th grade rather than learn in just one fixed section. Improved confidence through the repetition learning effect should contribute learning effect.
