Zull explores the brain and determines that in order to get ideas about learning we need to look within the brain (Zull, 17). He also draws upon the research done by David Kolb, who suggests that learning originates in concrete experience, requires reflection, developing abstractions, and actively testing those abstractions (Zull 18). Simply put, learning is a scientific method.
Zull believes that in order to better understand learning, we need to know where it happens, and what parts of the brain it happens in. He does not want us to assume that learning only happens in one place. Zull believes that the learning cycle is about life itself (Zull, 48). And that regardless of what we think, our brains are always learning and taking new shape, its just a matter of accepting and wanting those changes.
