Mr Miyagi was wrong

He's a great character, top bloke and Karate machine, but Mr Miyagi from The Karate Kid isn't a good teacher.



Sure, Daniel-san kicks ass at the end of the film (spoilers!), but his sensei's training methods are ordinary.

Why?

Because wax the car, paint the fence and scrub the deck were missing vital elements of effective training.

There was little supervision...
There was no continuing encouragement...
Most importantly, there was no partnership from doing it together.

When teaching someone how to do something, you need a generous dose of all three components.

Or else, whilst the trainee might pick up the skills via osmosis, they'll think you're a jerk.
