Computer Assisted Language Learning

A definition of CALL

Computer Assisted Language Learning (CALL) is often perceived, somewhat narrowly, as an approach to language teaching and learning in which the computer is used as an aid to the presentation, reinforcement and assessment of material to be learned, usually including a substantial interactive element. Levy (1997:1) defines CALL more succinctly and more broadly as "the search for and study of applications of the computer in language teaching and learning". Levy's definition is in line with the view held by the majority of modern CALL practitioners. For a comprehensive overview of CALL see ICT4LT Module 1.4, Introduction to Computer Assisted Language Learning (CALL): http://www.ict4lt.org/.

A brief history of CALL

CALL's origins can be traced back to the 1960s. Up until the late 1970s CALL projects were confined mainly to universities, where computer programs were developed on large mainframe computers. The PLATO project, initiated at the University of Illinois in 1960, is an important landmark in the early development of CALL (Marty 1981). In the late 1970s, the arrival of the personal computer (PC) brought computing within the range of a wider audience, resulting in a boom in the development of CALL programs and a flurry of publications. Early CALL favoured an approach that drew heavily on practices associated with programmed instruction. This was reflected in the term Computer Assisted Language Instruction (CALI), which originated in the USA and was in common use until the early 1980s, when CALL became the dominant term. There was initially a lack of imagination and skill on the part of programmers, a situation that was rectified to a considerable extent by the publication of an influential seminal work by Higgins & Johns (1984), which contained numerous examples of alternative approaches to CALL. Throughout the 1980s CALL widened its scope, embracing the communicative approach and a range of new technologies. CALL has now established itself as an important area of research in higher education: see the joint EUROCALL/CALICO/IALLT Research Policy Statement: http://www.eurocall-languages.org /research/research_policy.htm.
