This paper describes the implementation of blog system in an international distance course between Japan and Taiwan. In the study, blog was used as a tool to encourage students' reflective learning and communication. Findings suggested that blog was effective for students to document their learning, share experience and knowledge, have direct interaction with peers especially internationally. Students preferred blog over the LMS where this course builds an course Web site and they proved to use blog in developing their e-learning experience. We proposed the use of blog could lead to a technologically enhanced support for instructional strategy that serves as an informative model for other Web-assisted international courses
