By adopting a historical perspective, this edited collection of papers takes a fresh look at a key concept in applied linguistics, that of innovation. A substantial introduction advocates historical re-evaluation of this notion via exploration of its rise to prominence, while the ten subsequent chapters present in-depth case studies of apparently successful as well as ineffective innovation(s), from the early eighteenth to the late twentieth century. Language learning/teaching developments in Brazil, China, England, France, Germany and Italy are considered along with ‘global’ innovations in language learner lexicography, while the languages considered include Chinese, English, French, Italian, Latin, Portuguese and Spanish. Various types of primary source material are utilized, illustrating the possibilities of applied linguistic historiography for both students and academics new to the field. The book questions ideas of perpetual innovation and progress, supporting the adoption of more critical perspectives on change and innovation in applied linguistics and language teaching.
