brain scanA short time ago, the NY Times put out a fascinating story with pictures of scans showing what happens in the brain when solving a math problem.  They indicated four distinct steps: encoding (downloading), planning (strategizing), solving (performing the math), and responding (typing out an answer)

The steps themselves should come as no surprise to anyone who has taught math. Our lead instructor, Elayn Martin-Gay, has been teaching these steps in our award winning videos for over 20 years.  Science is just starting to describe what great teachers have known for decades and probably centuries.  I would like to see what the brain looks like during the fifth important step: checking the answer.
