Computers play several important roles in language learning including acting as a teacher or tutor by providing materials, guiding students, and giving explanations. Research has shown that computers and language learning are closely related and that information technology has penetrated all areas of life including education.

The document discusses how methods of language teaching have changed over time and research now shows that computer-based instruction is better than non-computer methods.
