FACULTYSHACK: And to give students a product that they wanted that would engage them in the kind of thinking that you wanted them to do?
SIZER: Right.
So overall his theory is not what is taught but how it is taught. Unlike Sizer E. D. Hirsch's idea is that Knowing stuff will help you understand. You need to know a certain amount of information in order to achieve. So its really the opposite of Sizer idea. Hirsch theory generated from his sons principal. He went to complain to the principal and his reply was,
“Our kids don’t need to learn about the Civil War. What they are learning at P.S. 87 is how to learn about the Civil War."
This is the similar theory to the way Hirsch wants students to think. It's all about the Product!!!
