The document discusses the evolution of computer-assisted language learning (CALL) through three phases: 1. Behavioristic CALL in the 1950s-1970s was based on behaviorist learning theories and involved repetitive drills without much authentic communication. 2. Communicative CALL in the 1970s-1980s incorporated more authentic communication based on the emerging communicative language teaching approach. 3. Integrative CALL from the 1980s onward utilized the internet and computer-mediated communication to facilitate collaborative writing and sharing of multimedia materials between students and classes.
