Here is an activity from Justin Slocum Bailey that can transform a classroom. I would suggest that the teacher start with the student in the class that is the least likely to get a compliment. For two reasons: to show that it can be done and so that the student doesn’t have to sweat it out til the end.

Every summer for the last ten years something magic has happened in Agen, France. Teachers from around the world have gathered in a friendly little town in southwest France and particpated in what many of them have called a life-changing experience. They come together because they have heard of a different way of teaching languages, a way of creating stories with their students and building a different kind of classroom. They come with open hearts and open minds and they leave with smiles and warm memories and many new friends. That is the magic of Agen.
