Interesting chapter, he is right in his approach, I was married to a b*tch of a teacher, she was just cruel hence now being an ex, she did however say in every class you have three sides of a pie , one are the bright kids ,one are the slow kids and the other are the average kids, you cannot teach all three successfully, so you teach to one group, and in every scene you always have two groups who loose out, there can be no winners, especially when the class sizes are around 40 kids. A sad reflection of society
