This paper introduces a case course with videoconferencing as a way of Synchronous Computer Mediated Communication (SCMC) for foreign language education in Japan. Research questions were to see the effects of videoconferencing on the learners' speaking ability and general English language proficiency, and also to see how the learners' international posture changed over time. Eight pairs of Japanese university English as a Foreign Language (EFL) learners experienced two semesters of 9-10 videoconferencing sessions per semester with an English teacher living in the Philippines. The task for the pairs was to discuss a social issue together with the teacher once a week. Their goal was to exchange mutual ideas on the designated topic. To lower the anxiety of speaking English as well as to practice discussion with fellow Japanese students, there was a 90-minute preparation period prior to each videoconferencing session. Pre-tests and post-tests results showed significant improvement in fluency, particularly in the amount of speech, and complexity of their speaking abilities. The learners also demonstrated progress in English proficiency. Their international posture stayed at a high level, but did not change much. However, their increased interest in working or participating in volunteer activities overseas was observed. The results indicated that the instruction based on videoconferencing helped improve learners' language and their global mind as a part of international posture. [For full proceedings, see ED564162.]
