This document discusses the history and evolution of computer-assisted language learning (CALL) from the 1960s to present day. It traces the development of CALL from early behavioristic approaches using mainframe computers to current integrated CALL using mobile devices and online exchanges. The document also examines different CALL approaches and pedagogies, emphasizing the importance of teacher attitude and shifting control to learners. It argues that modern networked environments and virtual exchanges can enhance language learning through asynchronous and synchronous dialogue.
