But only a few students will actually be motivated enough by classroom math to learn enough to later program games or drones. Most students develop an allergic reaction to anything that even reminds them of the horrors of school math.
You are right- which is why maybe a dual approach would be optimal- if you don't show intrinsic interest, you are self-condemned to the passive classic approach.
If you allow yourself to get involved (there must be of course those offerings, in some fun alternative).. i guess, it should be allowed for those involved in project schooling to train and recruit those stuck in passive schooling. This project system has a vulnerability though, it breeds specialists. So a teacher should encourage projects tackling different subjects and demand that everyone contribute to a project with calculus for example.
