That's a good tip GB; both as a memory aid and for making the FOIs meaningful.
It's a shame that many people see the FOIs as just something you have to do to get the ticket. More than 70 years of well-founded research lies behind them; and when applied will help you to be a competent and professional flight instructor.
Lot's of CFIs hone their flying skills quite quickly once they have a few hours under their belts. Same can't be said for the teaching bit in my experience. In fact, quite a few get lazy and worse.
