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 original technology used in the 1970s, but there was no clear idea how to use computers in the 1980s. Researchers later emphasized combining pedagogy with technology and focusing on language methodology over computer skills. By the 1990s, computers revolutionized CALL by allowing integration of text, sound, pictures and video. The document concludes that technology is now indispensable for education and an important complement to language teaching and learning. It also outlines 10 principles of good CALL, including adapting to learners, harnessing rather than serving technology, and helping learners learn better.
