If you’re training candidates for example for B1, B2 or C1 or whatever level of English within the Common European Framework for languages, why not conducting all the class in that language?
Yes, also announcements, arranging dates, logistics… all that is real communication, which complements the stuff proper of those levels of official examinations.
If we do so, our students will have a pretty chance of real communication in the classroom.
Thus we could “live” in that language, and we’re offering a naturalistic context for also real communication: it may be one of the best ways of training, right?
From the very meeting at the beginning of the class to saying good-bye, and recesses too. / Photo from: o-TWO-PEOPLE-TALKING-facebook www huffingtonpost com
