 What is feedback? Well, it's really interesting when you look at that from who's asking the question. When you ask teachers, what do they mean by feedback? Typically they talk about two of the three feedback questions and that is where am I going and how am I going. And they spend a lot of time saying that their role is to give students comments, give them critique, give them constructive content, this whole notion of how they're going relative to where they're going. When you ask students what is feedback, almost to a T they say feedback is helping me what to do next, the third feedback question. So my answer to your notion about what is feedback, it is about those three feedback questions. Where am I going, how am I going, or where to next. But the focus is different depending on what you ask. And another way of looking at what is feedback is if you have a concept of where you're going and if you know where you are now, then feedback should be aimed to reducing that gap between where you are now and where you're aiming to. This is why we put a lot of emphasis on telling students up front what success looks like so they can be part of the feedback cycle.
