I quit an executive position at the Knowledge Network to start a business based on my own experiences and University Education.
From my Father (born 1920) to my son we've been handled in various ways by the school system to facilitate peace, attention, and learning.. My son's was the worst experience so I'll briefly tell his story (I told you about the Orwell app and adverbs) I'm feeling guilty. My son was taught basic math by my Father. At the same time he was learning to read with me. He read "Animal Farm" at 4. Starting grade 1, he was ahead so it was decided he and his friend should do math by themselves. They finished grade 7 by the end of grade 2. What to do? Put him back into grade 3. He didn't try again until university.
Now a new fad has arisen pre k curriculum which might change things.
I partly created early-to-learn.com 3 years ago. It's not monetized. Now I'm attempting to run the gamut and unfortunately slowly create early-to-read, early-for-numbers and some really weird ones. These are all designed to present the research both good and bad, give parents and others the material available, create lesson plans and much more. I may be dreaming but it's a possible way to improve the learning experience for some students plus I have 2 grandsons.
