The document discusses the history and development of computer-assisted language learning (CALL). It describes the early phases of CALL which focused on repetitive drills based on behaviorist learning theories. Computers were well-suited to administering repeated drills and providing immediate feedback. Later, CALL integrated multimedia and became a tool for stimulus, discussion, writing, and research rather than just drills. Computer-mediated communication further advanced CALL by allowing sharing of documents, graphics, sounds and video to facilitate collaborative work.
