I've met a lot of people literally incapable of learning unless it was 1-on-1 instruction, and in every case they also couldn't or wouldn't do basic math. Teaching math to a class of kids must be brutal.

It's pretty rough, and it's why I think we need to completely revamp the education system.  Grouping by age makes no sense, and the need to establish good teacher-student relationships means that getting new teachers every year is a huge waste of time for everyone involved.  The current system is super inefficient, and most of the good practices are based on teachers going out of their way and doing unpaid work to improve the learning environment or teaching practices.
