Practice makes Practice
For about 15 of 25 years I have been a teacher I also coached a few different sports -field hockey, basketball, and soccer - in the after school hours. A coach's "success" is generally measured by the record of winds and losses racked up on game days. But teams and coaches put much more time into practicing than they do in the games that "count." At its most basic, the role of the coach is to teach your student/players the set of skills that they will need to take the field on game day and win. In many senses, not all that different from the role of the teacher in the classroom. Like the coach, in theory, we have lots of days of practice and then a game day that "counts." But in school practice, it often doesn't seem to work that way.
