This paper discusses group activities in an Oral Presentation Class. A large number of Japanese learners feel anxiety about their oral ability in official presentations. In the class, learners presented in groups which became gradually larger until presenting to the whole class. The purpose of this procedure was to reduce psychological anxiety of learners. The results of surveys targeting the learners' views on peer learning were analyzed. The learners considered the gradual increase in group size favorably and felt that it was necessary to practice their presentations repeatedly. It seems that gradually increasing the group size for presentations reduces learners' anxiety.
