You're the real heroine here.
I haven't been in our teacher's union for 35 years. Got fed up with them a long time ago.
Too bad the parents associations don't get on those inept teachers. It IS the ineptitude of the individual instructors who turn off the kids.
Parents have FAR more power than they realize. It takes some time to fight with the school and district, but it CAN be done.
Non-public schools are where the "expelled" students go - they don't just disappear into a vacume; the law requires that they go somewhere.
And I'll tell you - it's a LOT of fun to teach history to a kid who's every answer is to shout "NO" at the top of his lungs. No is a perfectly good answer - now, tell me why.
We need more people in this country who can say "NO".
Join it. Work your way up. Do a conservative takeover.... It's the only way we'll ever take our country back.
