> What are some of the reasons why the kids think the teachers are bad?

I'm not the parent, but my guess if any is that it has to do with the teachers' educative background. They're basically trained to teach biology as biology only, mathematics as mathematics only, etc. without putting 2 plus 2 together and spelling out the day to day usefulness.

A corollary question with a similar answer might be why the education system in just about every country (all?) is stuck with "traditional" course separations, as in maths, physics, biology, literature, etc. ¯\_(ツ)_/¯
