If I may be so bold, I disagree. I have a child who needs this interaction and learns best this way. It provides the structure, pace and immediate feedback that he needs.
I doubt that your child is sitting at a desk with you standing in front of him for five hours a day lecturing. If so, you’ve just recreated institutionalized schooling at home. I don’t believe that that is what you are doing, even though you may be interacting with your child several hours a day.
