In almost any course working with students to develop just a really excellent lesson is a great performance task. So much of what I feel like we've asked students to do in the past, just wasn't didn't have an all a real audience, and wasn't something they could see themselves needing to doing in the future. It's so great hearing you talk about these things and I want to let people know who are listening that you have provided us with a rich set of resources because we're barely giving the surface here. What where do we start in order to not just get so overwhelmed that we kind of shut down?
