a couple of things............
sometimes the instructor does stalls at a high AOA just because they enjoy them...........but it makes the inexperienced student feel nervous (to say the least) - but it can help to emphasize the teaching and learning points of the stall so not always bad..............
Also I find when I am practicing stalling and recovery that if I talk about what I am seeing/doing it helps................
so:
Approaching the stall - look for Nose high attitude, decreasing airspeed,lack of control effectiveness as you approach the stall
Stall itself - see that nose pitches down even with stick/yoke held back, buffet as airflow separates, high sink rate (see VSI), possible wing drop...........
Recovery - apply full power, control column/yoke centrally forward, wait until you have flying speed and rising............. recover from the dive and return to wings level, reduce the power and settle back to your normal attitude
It will also show the examiner that you know what is happening (situational awareness) and how to cope with it. As others have said - more practice at stalling and recovery is a good way to help remove the fear a bit.
I was always taught 'I hear - I forget' , 'I see - I remember' and 'I do - I understand'
Hope this helps
