Vocabulary learning such as exercises or daily tests is a burden for some students with low motivation for learning. This research focuses on whether repeated practices are effective or not for middle and lower level students. To examine this, I planned lessons that the students touched target words frequently and looked at the result of tests which were done before and after lessons. As a result, it was cleared that repeated practices were effective. In addition, it was figured out that the students felt importance of the explanation by teacher, using short sentences and repeated practices, by the questionnaire after this research.
