It's odd because there is a time and a place for everything including osmosis of some things. And with forced efforts like universal pre-k whereas kids should be learning socially and spatially they are instead packed into gridded rows with worksheets, and yet, don't come out the other side digested properly. Duh?
The key is avoiding the extremes and striking the right balance. My elementary school education was not as rigorous as currently being required, BUT, it covered the basics throughly and covered more than a sufficient amount of the basics and then some. And we were tested with weekly tests, quizzes, and mid-terms and finals, versus just one big massive blob these days or homeworks that become tests. IOWs, what was so wrong with the way we were all taught? I like the goal of improving things and I don't think standardization in and of itself is evil, but, the goal has been too deep in bureaucracy and too long with non-educators.
