I think what schools should do is besides teaching what to do, they should teach them why. Obviously, the most important is because it’s what G-d said. Some people though need other reasons before they reach that level. They should explain how it helps us connect to Hashem. That way, they help them build the Ahavah, which helps them to do things with kavanah. And when talking about aveiros, mention about a disconnect, and then teshuva which connects again.
Both parents and teachers can do this
