One of the most "striking" techniques demonstrated was when the teacher or student would comically hit a student over the head with an artificial daisy whenever he or she made a pronunciation miscue. The presenter remarked, in fact, that in all her years of teaching pronunciation she had never had a student complain about being corrected. And, after just an hour in the presence of that presenter, I don't doubt that . . .for a minute.
Two reasons most of what was presented was pretty much "in-applicable" to most of us in the audience. First, rapport. The presenter was one of those gifted teachers who almost instantly creates a safe and yet wildly creative milieu where learners will engage in extraordinary risk taking and not be threatened in the least. Second, and related, was the fact that many of the techniques demonstrated required that kind of "wide open" classroom setting to work effectively and especially--efficiently, in the first place.
The point: so often what can be done in a dedicated pronunciation class or language lab, with all its relational and situational constraints and social contracts, cannot be done in an integrated classroom setting where pronunciation is taught or attended to only piecemeal or occasionally or on a more impromptu basis. As research has demonstrated convincingly, instructors and students alike do not generally feel comfortable with much of how pronunciation is taught today. With good reason.
The affective and emotional context of pronunciation teaching is critical, even more so than for many other aspects of language teaching. In a dedicated "dramatic" class, strange things may work well; in an integrated "classless" setting, the rules and consequences can be very different. The "take way" from the dramatic, engaging workshop: Very little . . .
