The University of Aizu, in collaboration with the University of Waikato, has been investigating the use of open source, server-based software for the enhancement of English language instruction in Vietnam. In this paper, we describe recent educational, technical, and English language reforms in Vietnam which have facilitated a new approach to the teaching and learning not only of English, but also Computer Science concepts. The paper concludes with a brief discussion of the efficacy of using open source tools and highly structured instructional approaches for English language teaching in developing nations.
