Teaching math to average students without examples of real world applications is a waste of time. I think a lot of potential careers in science have died over the years because examples of its use that might get the juices of excitement flowing never surfaced.
I had to take physics three time in my life. First time was in high school. The teacher was okay if you were a natural math wiz — I flunked out. The second time was in tech school. Again the teacher was uninspiring — barely passed. The third time was in colledge. It was an applied physics course. The teacher was notoriously tough, but super inspiring. I got straight A’s and loved it.
