This book highlights the potential and the challenges of corpora in language education with a particular focus on the teacher's perspective. For this purpose, the study explores the relevance of the corpus approach to central paradigms underlying contemporary language education. Furthermore, a critical analysis investigates the persisting gap between research findings and their implementation in teaching practices. As a result, key factors in advancing the popularisation of corpora in language education are identified. A survey and a case study verify this gap and, importantly, underline the pivotal role of adequate teacher education if corpus-based language teaching is to make any significant impact on current teaching practices. The table of contents includes the following: (1) Corpus linguistics; (2) Corpora in language education; (3) Language awareness; (4) Learner autonomy; (5) Authenticity; (6) Data-driven learning; (7) Popularisation of corpora; (8) Language teacher education; and (9) Concordancing software. A survey, and questionnaire are also included.
