perhaps, since you're suggesting it's useful, you can tell me what subjects taught in a K-12 education necessitate the teachers challenging the system?
i'd consider perhaps high school literature and history teachers, but beyond that?
Math? Instead of teaching kids to memorize formulas and just apply to them to contrived examples, teach kids how match actually works in the real world and its applications. Great TED talk on this very matter:
- Civics/Politics
- Science (especially in districts that don't want to teach students about the theory of evolution)
- "Technology" (I had a computer teacher in HS who said F it and let us play around with hacking our test routers)
So we have math, literature, social studies, and science.
