Solomon, you had me! I struggled a bit with how many teachers were needed. What you describe in many ways is Montessori. There the children often teach one another. They learn and grow alongside a teacher that mostly oversees their work. It is an incredible setting much like you described.
I have four children that went to a Montessori school through 6th grade. They learned to be self-directed learners. This way of seeing the world has had an incredible impact on their life and also my husband and I’s.
It’s funny how something so simple to implement as a Montessori school is never considered in the current K-12 public education system. It promotes intrinsic learning which is key for a high quality of life.
