This document discusses the roles of teachers, students, and technology in computer-assisted language learning (CALL). It states that the teacher's role is no longer only providing information to students, but also informing and training students on new distance learning technologies. The student's role is to take responsibility for their own learning and become an autonomous learner. Technology takes on multiple roles as a tutor, information source, speaker, and interactive tool. It facilitates new contexts for learning where students have more control over content, time, and place of study. The document provides references and mentions a website for English language learning using this method.
