The curriculum consists of a storybook and instructional manual. The curriculum is structured so that children are made aware of problematical concepts in their own life, and then required to practice judge relations of concepts on their own experience.

This is a departure from the way that philosophy education has been traditionally thought. New philosophy education has a strategy as children develop reasoning in the thinking by themselves thorough cycle of revision of thinking.
