The best way to go is as you say, raise class sizes to 30 pupils, and fix the curriculum. Get down to the basics of reading, writing, arithmetic and citizenship. Eliminate all of the soggy feel good BS like “black history month” and the like.
Lose tenure, and make them “at will” employees. They stray off the curriculum, they get fired, period.
These POS’s are so obnoxious because they know they can’t get fired without significant effort and some sort of “cause”. Poor performance, a crappy attitude, being a stinking communist, just isn’t enough (though it should be).
Funny thing was when my wide was a teacher she was all gung ho for the NEA line. Now that she’s a principal, she wants tenure gone, and wholesale firings of entire school staffs.
She’s also finding out that many long seniority administrators (tenured ex-radical communists) need to shown the door as well. Many of them simply refuse to document the egregious actions of these crappy teachers and view the school as a “make work country club” for adults, the children/parents be damned.
My wife was a teacher and brought Jesus directly in the class room. They all love her today.
What we need beyond your great ideas is corporal punishment for high schoolers administered by certified disciplinarians who are exempt from suits and who are monitored on video as they swat the crap out of the unruly. You Don’t have to do it more than 5 times to shut everybody up!! Take some gang banging POS and pound his fat ass with 4 swats from some big jock coach who has sovereign immunity and it is back to education rather than tattoos and babysitting. WE LOST THE SCHOOLS AFTER INTEGRATION BECAUSE WE WERE AFRAID TO SWAT BLACK KIDS!!! ohhhhhhhh truth hurts. Swat the little bastards of alllll races if they do not conform to the rules!!! You might save one from a life in prison!! And he might learn some Shakespeare. My God this system sucks.
