The issue of softening educational standards, I think, lies almost entirely with our touchy-feely attitude that we can't hurt anyones self-esteem. We can't give "F" grades because that means failure and it hurts little Johnny's feelings. Well, guess what? JOHNNY FAILED! He failed to master the material even at the lowest level (you just have to remember 60% of everything you're told... not that hard), hence he failed the subject.
Some schools are getting rid of grades completely, moving to a check minus, check, check plus system that aren't descriptive at all. With no fear of failing, there's also less drive to succeed. Why bust your butt to get that check plus when you can sit on your ass and get that standard check? Cause you know they'd do it on standard bell curve with the lower 20% being check minus, the top 20% being check plus, leaving the other 60% to the middle. So now you only have to master 21% of the material to "pass".
I'll leave the blame on this one to the far left in their eternal quest to make absolutely everything equal. To them there's no such thing as being smarter, dumber, stronger, weaker, faster, slower, taller or shorter than anyone else. Well guess what? Some kids are dumb. Some kids are destined to become janitors, or McDonalds workers, others are destined to become doctors, astronauts, executives etc... Am I smarter than the guy who works at the convenience store and can't string together a coherent sentence or tell me where on the map Iraq is? Eh, maybe not... he may be a mass of untapped potential. But chances are I am smarter than he is... or at the very least I work harder than he does (as I have a High School diploma and he does not... not to mention a college degree).
I am smarter than some people, dumber than others. I almost failed statistics in college, while my friend aced it. At the same time I schooled him in calculus. If the far left had its way, we'd all get a pat on the back and averaged grades because we're all just as good. I admit I'm a statistics moron, it's like greek to me. It doesn't hurt my self-esteem. In fact having the distinction of what I'm good at (computers) and what I'm not (a great many things) has allowed me to better define myself. I feel better about myself as a result because I *know* where my strengths and weaknesses lie. This is what our education system right now is trying to eliminate.
