Abstract: Web 2.0 tools and social networking approaches give unique opportunities for students across national borders to communicate and collaborate. They are especially suitable for fostering foreign language learning and intercultural understanding as well as 21st century skills as they give authentic learning for students to practice the above skills. This paper describes a case of a joint telecollaborative class between a class in Karoli University, Hungary and that in Kanda University of International Studies, Japan, The students in two classes compare and contrast information on a selected topic and collaborate on final presentations. In the class, both an asynchronous communication tool (i.e., Facebook in this case) and a synchronous tool (i.e., Skype in this case). In addition, a collaborative tool (i.e., Google Docs) and a presentation tool (i.e., VoiceThread) were used both synchronously and asynchronously. The observations found that students would use those collaborative tools progressively as they gained more experiences.
