I believe one major aspect of learning ballroom dancing is training muscle
memory. To this end, it seems that using mainly verbal instructions, which
most instructors use, is not a very efficient method.
Wouldn't it be better to have some computer controlled mechanical device
attached to the student that limits his/her motion to the correct one as
he
repeats each dance step, or sounds a beep near the area where the student
makes a mistake (e.g. head facing wrong direction, arm too low...)?
Another method is based on the assumption that you can train someone to
judge dancing much faster than training the person to dance. Once you
trained the person to judge dancing, all you have to do is give him a
mirror
or a camcorder to see himself learning to dance, and he should be able to
judge and improve himself, right?
