I know about education; I'm in the field too.
The real problem in modern education in the USA is that the Republicans entered into the issue. I'm not saying their ideas are all horrible; but that the political fight was so much smaller so the teachers and schools were not in the middle of a political culture war. You see, what really started the mess was that public polling showed voters ranked education higher in priority than in the past and that turned it into a two party political football. The rest is a bunch of policies and ideas which have zero basis in reality and everything to do about sounding good, getting votes, and political BRANDING. SO BOTH PARTIES WORK TO DESTROY IT like everything else they touch these days. That has harmed the system greatly which only reflects the broken political system, just another thing that precedes the collapse of a once great democracy.
Furthermore, education is not a business. You can't turn education into an easy statistic like sales and students are NOT customers!! They are not supposed to be happy customers with a "your #1" sticker handed out to everybody and every parent is immune from criticism. The culture is all fucked up; used to be the student was to blame, now the special snowflakes are perfect and the teacher is always the problem.
Yes, technology needs to be PROVEN before it's allowed to be used. SCIENCE should decide everything. That means parents (voters) will be pleased. automated tests have yet to be intelligent. I can interview a student and assess them quicker and more accurately than any static test plus they can't ever fool me. But in the land of lawsuits somebody will be upset they didn't get their "your #1" sticker... while the multiple choice exam allows many times more to sneak bye or undeservedly fail.
We can't even adjust school hours to fit best with sleeping patterns of the children when that stuff has been known forever.
Science says that middle school kids shouldn't even be educated conventionally. They need emotional development training and stuff so out of the norm many people would revolt. Most education problems are psychologically based and their parents and environment are HUGE factors. If you apply developmental psychology instead of acting like it doesn't exist, you would turn poor performing students, future criminals, and fragile suicide kids into good students and functional adults. Naturally, parents would be upset because they'd have responsibilities, something which they avoid like everything today.
Parents want free daycare. Some need it too. Snow days not only cause parents to call in irate, but it also means some children DO NOT EAT.
There is so much wrong which has so much more impact-- but we only can discuss a FEW issues and wave some shiny new toy in the public's eye... like they were children.
