Teaching English as a Second or Other Language (TESOL) is a multifaceted academic discipline requiring training in linguistics, language acquisition, language pedagogy, methodology, materials development, testing and research, curriculum and syllabus design, programme administration and cross-cultural communication. This series of advanced textbooks in TESOL comprises individual volumes addressing an identifiable subfield within TESOL in more depth than would be covered in an introductory textbook to the area as a whole. Each volume is designed for use alongside taught module-length topics on TESOL degrees. As a whole, the series provides a comprehensive introduction to the subject.
