This book brings together current thinking on informal language learning and the findings of over 30 years of research on captions (same language subtitles for the deaf and hard-of-hearing) to present a new model of language learning from captioned viewing and a future roadmap for research and practice in this field. Language learners may have normal hearing but they are ‘hard-of-listening’ and find it difficult to follow the rapid or unclear speech in many films and TV programmes. Vanderplank considers whether watching with captions not only enables learners to understand and enjoy foreign language television and films but also helps them to improve their foreign language skills. and Teaching will be of interest to students and researchers involved in second language acquisition teaching and research, as well as practising language teachers and teacher trainers.
