I went to a Clinton Anderson workshop (he's a horse trainer, in case you were unaware) in June. He said something that I thought was brilliant. "Frustration begins where knowledge ends." Even though he was talking about horses, I thought this really applied well to students--or anyone else for that matter. A good example of this, at least in my classroom, is when kiddos are reading. When do the behaviors start? At their frustration level. Where does their frustration begin? Where their knowledge ends. Anyway! What are your thoughts?
