So, do you have kids? If not, it doesn't invalidate your observations, but it definitely puts you at a disadvantage. You just have no idea what you don't know until you spend 24/7 raising a child. I have two kids. They both learn differently and at different rates. As a result, we teach them differently. However, we are still teaching them what is appropriate to their specific stage of development (I call that age appropriate, but you may not). So, I totally agree that learning should be unique to the individual, but I also think there are very real and distinct stages of growth that each individual goes through and for learning to be most effective it needs to take that into account.
