It seems to me like a process that begins with an initial evaluation to see where the educator is at when they begin teaching their course that is followed with periods of monitoring then evaluating. Initial evaluation is important in teaching and learning because it tells the leader what to teach, who needs to learn it, and how best they will learn. Count those two sense.
Evaluating should be a given. Teachers are always learning and they think you should too. A Good teacher wants to know how to be better. Monitoring? It has been a long time since I went to school so I am confused about what that would be.
