Stalled it with a negative angle of attack?

Why do you assume that the attitude of the airplane has anything to do
with its angle of attack?

The attitude created by the the tail dropping after the nose wheel
impacts the ground creates the positive angle of attack; airplane flys
again... Terrified student crams the stick forward, lowering the
attitude AND angle of attack and flys the airplane into the ground with
the wing unstalled.

Hopefully the student after repairing the $170,000 airplane will receive
instruction on maintaining the proper attitude after the "bounce."

Since I fly mostly aerobatics I do test the relationship between
attitude, angle of attack and speed rather frequently but those cases
where you can, in reality stall the wing while nose down hardly apply in
this case.

Now if you told me the student was attempting an outside snap roll on
takoff, then we would be there... nose down, stalled (and dead).

That may have well been what happened, though it's certainly possible
to have a nose down attitude and have the AOA exceeding the critical
AOA.
