Computer Assisted Language Learning (CALL) uses computer technologies like word processing, presentations, simulations, and multimedia to promote language learning. CALL includes using the internet for activities like email, chat, and browsing the World Wide Web. Teachers use CALL because it can interest and motivate learners, provide more access to information, allow flexibility in instruction, and better support individual learning styles and strategies. One use of CALL is for drill and practice, where computers provide stimulus, receive student responses, and give immediate feedback, following behaviorist learning principles. While CALL has potential, it cannot replace teachers, and its effectiveness depends on how it is used to meet language learning goals for individual students.
