I think most people look at education through very-nostalgia-filtered glasses.
Very few people would argue that medicine or technology in the 70's was better than today; because most of us are simply consumers of the end products. But we all went to school and that makes us think we understand education.
The fact of the matter is that the theory behind teaching changes, the subject matter changes, and the classroom composition changes.
In the 'old days' when I was in school (graduated high school in 1982):
- lessons were taught in one way, lecture style with with learning expected to happen by rote memorization. We KNOW that this is not the optimal way for everyone to learn and now most teachers try to incorporate multiple methods of learning.
- handwriting was taught (although I never learned cursive) as a necessary skill. Today that is not the case, but I did not get classes in computers or French.
- classes did not include kids with any kind of mental or physical disability. My wife has taught elementary school for 30+ years and she routinely will have 1 or 2 kids on the autism spectrum in her class, along with a couple of kids who don't speak English and maybe an ADHD kid to boot.
I live in Vancouver (Canada). I
generally trust the government, who set the curriculum, to always have the best interests of the kids in mind (even when I disagree with their politics). The worst that I have seen in the past 20 years was a government that cut the real budget which resulted in larger classes and fewer teachers. Even that government did not do anything that changed the actual content of the curriculum in a adverse manner.
It does happen in Canada, recently the newly elected government in Ontario scrapped an updated Sex Ed curriculum that was created by experts to replace a very old and out-of-date curriculum. This was pure politics, basically pandering to social conservatives; yet, they are backtracking on bits of it, as everyone recognizes that you need to teach modern information not stuff that is 20 year old.
If what I read about the US system is correct your education is much more politicized. It is unfortunate as politicians are rarely experts in anything except getting elected and drinking deeply from the public trough! :-)
Anyway, this will be my first and last word on this topic...I don't want to bore you all to death with my walls of text!
