Copied from a message board, where someone asked "how important is it to be like a teacher when homeschooling?"
I think it's important to recognize that institutional schooling represents a sort of contracting out of the academic education portion of the responsibility for raising a child, and that this is a relatively recent practice in the scope of human history. The idea of having separate roles for "teacher" and "parent" is a little artificial.
Imagine if you will that the government began providing universal free meals for children. Cafeterias would be set up in neighbourhoods and three times a day children would be delivered there to receive the meals cooked and served by trained nutritionists. These nutritionists attended special training in handling the cooking needs of large groups, and in managing the crowds of children, their table manners, their social behaviour during meals and so on. This quickly became the norm, with almost all children reporting to their nutritionists for their meals. If you as a parent decided to feed your children at home that would be allowed but considered a little unusual.
So if you decided to feed your kids at home, you would not say "It's important to be clear about my dual roles -- at certain times I'm their mom, and at certain times I need to act like their nutritionist. I need to learn how nutritionists act in order to successfully feed my kids at home."
A little silly, don't you think?
I see the distinction between "being a mom" and "being a homeschool teacher" in a similar light. They're not separate roles. We tend to see them as separate because culturally we have made an artificial separation, assigning the roles to different people. If they're not going to different people, they don't need to be different.
