Book excerpt: Corpus Linguistics for English Teachers: New Tools, Online Resources, and Classroom Activities describes Corpus Linguistics (CL) and its many relevant, creative, and engaging applications to language teaching and learning for teachers and practitioners in TESOL and ESL/EFL, and graduate students in applied linguistics. English language teachers, both novice and experienced, can benefit from the list of new tools, sample lessons, and resources as well as the introduction of topics and themes that connect CL constructs to established theories in language teaching and second language acquisition. Key topics discussed include: • CL and the teaching of English vocabulary, grammar, and spoken-written academic discourse; • new tools, online resources, and classroom activities; and • focus on the "English teacher as a corpus-based researcher." With ready-to-use teaching vignettes, tips and step-by-step guides, case studies with practitioner interviews, and discussion of corpora and corpus tools, Corpus Linguistics for English Teachers is a thoughtfully designed and skillfully executed resource, bridging theory with practice for anyone looking to understand and apply corpus-based tools dynamically in the language learning classroom.
