Education is like a lot of others things. Failures and lack of success can be blamed on many factors and many groups. But, in the end, personal responsibility is the major factor. In the case of education, parents and the kids themselves. There are many poor quality teachers, but most are capable and competent. Many are excellent. But what do they teach? Remember the 3 R's? Reading, wRriting, and aRithmetic. That use to make up a major portion of education and was beneficial in every day life. If you master those, you can get by. May need to put more emphasis on those before moving on to all the other stuff.
First response to educational problems is to spend more money - hire more teachers, give them raises, build new buildings, etc. Throwing money at a problem just wastes money. If that were the solution, we would be in great shape. We don't get our money's worth in terms of what we spend per student compared to other countries. At least I have read that.
I attended the smallest school in my state. Less than 100 students in the high school. No choices of classes, everyone in each grade took the same classes. Too small to offer more choices. Hard to get the best teachers or opportunities in such a small school. But was able to go to college, get an engineering degree and graduate at the top of the class. Personal responsibility - expect to do well and put the effort in. Look for people to help you instead of looking for someone to blame for things.
Our daughter went to public elementary school. We were not real happy with what was happening there - a couple of excellent teachers, but a couple of real duds. The system treats everyone the same, good or bad. The real world should reward the best and penalize the one's that don't perform. We were thinking about home schooling. This was years ago when home schooling was not very accepted and was viewed with hostility by some. We visited the middle school and the high school to help with our decision. They were very proud of a couple of their programs. One was to require the students to take home an egg shell for the weekend and bring it back on Monday without breaking it. One was to take home a doll that would regularly cry and require attention. These programs were supposed to teach responsibility. No discussion of the 3 R's. This school district was one of the top districts in the state.
Our decision was made and our kids were home schooled. At that time, you had to get "permission" from your local school district in order to home school. We were told that they would probably not be able to go to college, not be eligible for scholarships, and would be irreparably harmed by our actions . After a few years of the home schooling, our daughter asked what was required to finish. My wife gave her a list of courses and books and told her that when she finished those and passed the tests for them, she could "graduate" from home schooling. She finished high school at 15 while also taking college transfer courses at the local tech school. She attended the local state university for two years and took only the necessary courses to allow her to apply to vet school. She was accepted to vet school when she was 18 and graduated with high honors when she just turned 23. Remember that our school district had warned us that we were doing irreparable harm to our kids. I did brag a little in this, but to make the point that success in education is a personal responsibility and a responsibility of having kids. If we turn our kids over to the government or the "system" for the whole of their education, we get what we have.
