As you work through the module, you will be invited to complete a number of teacher development tasks, all on the topic of TBL. The tasks you are asked to do are all examples of task types that you could use (with appropriate modifications) with language students. For this reason, I recommend that you do at least some of these tasks with a colleague, if at all possible. That way you will get a much better feel for tasks from a learner's perspective. You will also be able to see sample material designed for students to illustrate ideas and to provide the data or material for some of the teacher tasks.
