I can’t speak for everywhere else, but I have my own theory as to why the school system in my home town blows, and my poor grammar skill are going to shine in the next several sentences.
In one word POLITICS. In my home school district they have a history of not necessarily hiring the best people available for open positions. However, there is a direct correlation between those hired and their relationship to members of the school board, the district superintendent, or current faculty. To me it is disturbing the sheer number of sons, daughters, nieces, and nephews that have been hired the last several years. I could be wrong, but there is a definite pattern.
I am a product of our education system and the older I get the less impressed I am of my educational experience. I am by no means a genius, but I wasn’t very challenged in grammar school. Unfortunately, this caused me to develop poor study habits, and I paid the price in high school and college. I still managed to graduate with an engineering degree despite taking a few years off in the middle of my college education.
The thing that burns my backside the most about the whole thing is despite holding a B.S. in engineering, and completing more math classes than I care to remember I am not qualified to teach in the public school system in Illinois. I can, and have, taught classes on the college level, but because I do not have an education degree it a no go in the public system.
