Expositions: Corpus Linguistics in EFL Language Teaching: Insights From Research and Practice

Corpus linguistics can provide curriculum developers and teachers with theoretical foundations and guidance when deciding learning objectives, identifying materials and methods, and evaluating learner outputs. In this Exposition piece, we discuss how corpus linguistics can inform EFL language teaching in the areas of materials creation, skill development (reading, writing, speaking, and listening), and evaluation, with special attention given to lexico-grammar and vocabulary. We also provide examples from courses delivered at Waseda University to illustrate these approaches.
