I thought everyone knew the word escarpment. At least everyone in their '60s who watched Johnny Weissmuller's Tarzan movies. While talking to my Granddaughter who is attending college right now, I have noticed the lack knowledge the kids are graduating high school with today. They don't seem to be able to use pen and paper to figure out math problems. All my grand-kids are allowed to use calculators in school which is something I was never allowed to use in school. The don't even know much history and a lot of it they do know seems to be different than what I was taught or even lived through. They don't seem to be taught proper grammar or sentence structure either. I think the kids today are being taught how to play the system and get good grades without learning even the basics. My granddaughter graduated with very high grades and seems to have learned very little.
