By showing them the approach, teaching them the benefits and showing them the results? By giving them more information, so they can want to adopt the same mindset themselves? Because not all teaching, showing and informing is "brainwashing"?
But this guy is not a teacher; he's a coach. This is math-sport. Teachers can't just abandon the part of the class that doesn't already show demonstrated aptitude and/or commitment.
The football team is to the gym class as the math-sport team is to the math class.
All the more argument why adopting the mindset is better than adopting the specific approach or program. The approach might be good for competitive-level math, but bad for the classroom. The mindset will allow teachers to adapt those ideas so they can be appropriate for the classroom.
