A very different approach, emphasizing the spoken language, became popular in the middle of the twentieth century. It involved a systematic presentation of the structures of the L2, moving from the simple to the more complex, in the form of drills that the student had to repeat. This approach, called the audiolingual method, was strongly influenced by a belief that the fluent use of a language was essentially a set of “habits” that could be developed with a lot of practice. Much of this practice involved hours spent in a language laboratory repeating oral drills. Versions of this approach are still used in language teaching, but its critics have pointed out that isolated practice in drilling language patterns bears no resemblance to the interactional nature of actual spoken language use. Moreover, it can be incredibly boring.
