Re teaching the stall exercise with PP vs white board.
I only teach with white board and do not allow my FI students to use PP.
Why ? because for the last three PPL what I taught on the ground exercise was significantly different because what worked for the guy with an engineering degree would have been useless to the guy who ran a landscaping business, and what would have worked for him would not have been the right lesson for the professional motor mechanic....
The white board format allows an infinite number of ways to present while the use of PP encourages rote repetition at the expensive of understanding.
Just because it is new and on a computer does not mean it is better.....
