Education is a technology that is built upon the natural phenomena of the human brain. It is only though changing the structure and function of this organ that we learn. Some experiences change the brain quickly and permanently; some experiences change the brain slowly and reversibly. Regardless of the outcomes a teacher plans, the results of the teaching experience depends on the nature of the experience for the learner. Regardless of what we expect, some experiences will be temporary or permanent based on the physiology of the brain.
