Regular readers know that I am a big advocate of Task-Based Language Teaching. In this video Dr. Rod Ellis discusses some of the problems/issues/misconceptions in TBLT. One of my favourite parts is task complexity, another is teacher education, though the latter is rushed through much more than it ought to be.
If you like this video, or just don’t have an hour to spend on it (which is a shame), you can have a look at my previous post on how to actually do task-based teaching, which is a rough and dirty guide.
