When was the last time you were actually in a classroom?
Or is this something you were just told and don't actually have a real clue.
I teach History everyday, I'm there to teach and not to preach. I put the facts out and how a student digests that info is on them.
As for math, there are a lot kids doing advanced math. The need for calculators speeds up that ability to teach these kids this. Gone are the days of a instructor working out a problem on a 12X20 black board for days on end. It's not practical.
As for your assessment of English and Language arts, you're so far off its unreal.
As for proper punctuation, I can tear your post apart as you've made several errors.
Again, this all begins in the home. You're not happy with the the current state of education, take an active role in it. In the end, your children get the education you pay for and are willing to provide.
