Although foreign language instruction has seen a big surge in the integration of technology- enhanced forms of delivery of knowledge and interaction, research focusing on the value of computer- mediated communication (CMC) in the language classroom has not been extensive and has not received wide coverage. This article examines and outlines general findings regarding the educational capacity, benefits and limitations of three major CMC tools (text-based chats, discussion boards and wikis) for enhancing foreign and second language acquisition processes. Some insights are offered into the importance of specific CMC tools for supporting the collaborative nature of learning and learner autonomy, fostering students’ reflection and critical thinking skills and affording higher motivational gains and engagement in the language learning process.
