Computer-assisted language learning (some definitions)

Michael Levy (Computer-Assisted Language Learning: Contexts and Conceptualization, OUP, 1997) defined CALL as "the search for and study of applications of the computer in language teaching and learning". It is a field which has been constantly evolving both in terms of pedagogical changes and technological advances. To the possible advantages of multimedia applications, the use of the Internet has added real and global communication (how to learn with Computer Mediated Communication is a growing field of investigation) and a huge amount of materials, linguistic data and online resources. New web 2.0 tools (blogs, wikis, podcasts) are offering new possibilities to communicate, collaborate and share learning and knowledge.
Ken Beatty (Teaching and Researching CALL, Pearson, 2003) gives a broader definition of CALL that takes into consideration its changing nature: "any process in which a learner uses a computer and, as a result, improves his or her language".
A further definition for CALL can be found in the Wikipedia article:

Computer-assisted language learning (CALL) is an approach to language teaching and learning in which computer technology is used as an aid to the presentation, reinforcement and assessment of material to be learned, usually including a substantial interactive element.
