Paul Lubbers, a USPTA Professional, gives this seminar presentation on how to establish a model for error detection and correction in a student’s strokes. Some of the questions he answers include: How do you observe? How and when do you correct? What type of feedback do you give the player? Lubbers also discusses how to know and relate to the player, and he gives an example of a common error, lack of depth and pace on forehand, and explains how to correct it.
