The document traces the evolution of computer-assisted language learning (CALL) from the 1960s to the present. It discusses how the language laboratory was the initial technology used in the 1970s, but there was no clear idea how to use computers in the 1980s. Research in the mid-1980s emphasized that CALL requires knowledge of both pedagogy and technology. Principles of good CALL emerged, emphasizing that CALL should be learner-centered, adaptive, engaging, and help learners learn better by harnessing technology to meet their needs based on research.
