Has math, reading, or sex changed much in the past 20 years?
Personally, I'd be thrilled if schools around the country used textbooks from 1950.
But these books are just filled with a bunch of words. There are no pretty photos, graphics, and inserts relating the material to minorities, women, and liberal bias. Surely, you not want these things to fall in the hands of our dear children!!
Try the books from the 30's and 40's. They were really hard and so were the teachers. To graduate from high school in those times was more than equivalent to getting a college degree. It was much tougher yet in the early 1900's. To get out of high school then they had a final test that many college professors these days could not pass.
So would I. I've gone online and visited used book and even antique stores to find some good old-fashioned math textbooks, but I just can't find them.
So, yeah, I would be upset if my kids school were using texts from the 80s, the height of the garbage period.
Similarly, schools have returned to real reading, and sounding out words. Texts from the 80s were based on sight reading, and hence are worthless.
Not that this has anything to do with sex ed, of course...
