Parents can and do learn along with their kids.
I did.
And both my sister-in-law and my best friend went to college for teaching degrees.
Imasked them both the same question and that was whether a teaching degree actually taught them to teach. Both of them, separately, told me no, nothing in their teaching degree prepared them for classroom management, or taught them HOW to teach, that you were expected to learn as you go as a teacher
My best friend, who is excellent at math, said that she’d have been far better off with a real math degree than the watered down crap they gave her for her teaching degree. She said it was not rigorous or thorough enough.
Any parent could have become a teacher if they chose. It’s not a matter of intellectual ability, but of commitment to see the student learn and no one has a greater vested interest in that than the parent.
It’s also common knowledge that the students who do the best in school are the ones with the most parental involvement, which in effect means the parents were essentially doing the home schooling using school materials, and the school is taking credit for it.
I was insulted when W. made TX schools send out an agreement to parents to help kids learn to read. Our kids were reading before K. One kiddo had a horrible K teacher who was so very angry at how advanced kiddo was. Why angry?
We happened upon a church pre-school (6 hr./wk) where the parents were involved with their kids’ education. All but one from that pre-school class graduated HS with honors. I taught middle school and could point out which students attended that little school and had parental support. Early parental involvement, a good foundation and it’s almost a guarantee the child will succeed.
