Let’s turn this on it’s head..”If home school/religious school/private school don’t learn, then they are failures. Every method of teaching has failures. If you’re goal is 100% success, everyone is a failure. Or are you going to tell me that every home schooled (or private school, or religious school) student succeeds?
Your last sentence “Obviously, the government institutional schools aren’t teaching. It’s the parents who are.” is simply not true. Even though I and my wife helped at home, I will guarantee you that I did not teach my kids algebra, trigonometry, or biology. The teachers at their high school did, just as their elementary and middle school teachers did most of the teaching in their subjects. The fact that we helped them study at home in no way refutes that.
How do you **know** that it was the teachers who taught the math? Where are the studies? How do you **know** that the school didn't just send home the curriculum? Certainly, your children did homework IN THE HOME from textbooks. With testing the child before the class, immediately after class, and then after studying the chapter and working the problems in the home, it is impossible to know where the child acquired his knowledge.
Personally, having a goodly amount of math and math based science, I testify that 95% of the math I learned I taught myself. The teacher was there merely as a reinforcement. The real learning took place **before** class by studying the chapter and working the problems, and then again after class by working the problems again and again.
This is an assumption on your part.
Without testing the child before class, immediately after class, and then again after studying the text and doing projects in the home, it is impossible to know who did the teaching or where the learning occurred.
If you’re goal is 100%
Every method of teaching has failures.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I can’t chase a strawman of your creation. At no time did I state that my goal was 100% success.
The success rate in the government’s inner city institutional school is considerably less than 100%.
