Language teaching came into its own as a profession in the last century. Central to this phenomenon was the emergence of the concept of "methods" of language teaching. The method concept in language teaching—the notion of a systematic set of teaching practices based on a particular theory of language and language learning—is a powerful one, and the quest for better methods was a preoccupation of teachers and applied linguists throughout the 20th century. Howatt's (1984) overview documents the history of changes of practice in language teaching throughout history, bringing the chronology up through the Direct Method in the 20th century. One of the most lasting legacies of the Direct Method has been the notion of "method" itself.
