However, users often lose their motivation for learning during the process of study. In this research, we employ games as one of ways to refresh learners during learning. Experiments are conducted to evaluate the effect of playing games during the rest time between learning. In the experiments, participants are separated into three groups: one group plays a busy game, one plays a calm game, and one plays nothing in the rest time. Then, they are asked to solve numerical problems as many as possible in a predetermined time. Using these groups’ experimental results and questionnaires, we assess effect of these games. 1. ࡣࡌࡵ ࡇࡀ࡛ࡁ㸪⪁ⱝ⏨ዪၥࢃࡎᴦࡋࡴࡇࡀ࡛ࡁࡿ㸬ࡲࡓ㸪 ⌧ᅾ㸪ࢡࣛ࢘ࢻࢥࣥࣆ࣮ࣗࢸࣥࢢࡸࣈ࣮ࣟࢻࣂࣥࢻࡢ ⩦᪉ἲ࡛࠶ࡿ࢚ࣥࢱ࣮ࢸ࣓ࣥࢺ࣮ࣛࢽࣥࢢࡀᏛ⩦ពḧࢆ ᬑཬຍ࠼࡚㸪ࢫ࣐࣮ࢺࣇ࢛ࣥ㸪ࢱࣈࣞࢵࢺ࡞ࡢࢹࣂ
