Many language teachers use Information and Communications Technology (ICT) in their classrooms to create tasks, quizzes, or polls with general online learning platforms. Few teachers have experience, however, of incorporating online corpus tools in their teaching or assessment practices. This paper will explore how autonomous learning can be fostered by gradually introducing freely available lexical databases, online collocation dictionaries, pronunciation guides, concordancers, N-gram extractors, and other text analysis tools for vocabulary building, skills practice, or self-checking. Tasks used with English as a Foreign Language (EFL) undergraduates and teacher trainees on a Master's Teaching English as a Foreign Language (MA TEFL) course will be presented. I will also explain why having some familiarity with linguistics research can enable teachers to use these applications more meaningfully.
