What i am understood about the chapter is like; we must learn in the home correctly. In my opinion is difficult to the teachers in the school teaching correctly because, if a student is wrong is more difficult to explain to him/her to the correct way. Or viceversa, I remember a lot of teachers that speak awful, and I sayed to him: teacher is like that, and the teacher is like oh yes sorry. I am wrong and then like in a couple of days the teacher sayed the same all the time. But how the teachers can be wrong, is supposed that they have to be in the correctly. So the teachers can give us an appropriate knowledge in the school.
