Even more, it confuses unconsciously learned skills and skills learned by repetition. Repetition is not always the best or the only way to learn those skills that get mastered at an unconscious level (though it's definitely an important way to achieve unconscious mastery at some things). These sorts of skills often involve physical activity, movement, writing and coordination generally. If a person begins with "poor form" in such a skill, repeating the activity only makes the poor form more ingrained.

Alternative method include something directly guiding student physically and practicing in such a way that you get immediate feedback if you are wrong.
