Just as a pilot is "ahead" of his airplane, an instructor should be "ahead" of their student. After teaching dozens of students I have noticed that they all tend to loose control at the same point in certain lessons. As they step out of thier car I already know when they are going to loose control that day. This is because I have seen it happen so many times. Early on it will be right turns, later watch out for base to final in a right pattern, there is a funny spot just past the threshold right before th airplane passes them by when landing. Anyone that has intsructed for any period of time knows where all the stumbling points are. If you tell the student what is about to happen, and how this is about to become tricky, they don't panic. If you are right there talking them through they will do fine. Now you have introduced the student to the phenomenom , let them experience it successfully and helped create self confindence in themselves and trust in you.

Instruction is not standing beside the student in silence and claiming that you will leap into action should something go wrong.
