I have a pretty short, but powerful tip for you this time around.
What happens when you're asked a question? Makes you think, right? Makes you learn more, right? And what happens if you're told something you already know? You get frustrated that your "teacher" doesn't recognize that you already know what he/she is telling you. Think about that the next time you're instructing. What would happen if you asked more questions than you currently do?
Instead of "Look further ahead," you might ask, "How far ahead are you looking?"
Instead of "Squeeze the brakes hard," you might ask, "Are you squeezing the brakes hard, or stabbing the brakes?"
Instead of “Hit the apex,” use, “Are you hitting the apex?,” or “Where’s the apex?”
What do you think? Would this make you a better instructor? What other questions could you ask?
