Eric Jensen suggests that IQ is not static. It can be changed! This is really very important when looking at children in impoverished and traumatic situations. Place-based learning is a highly effective way to help these students make the connections they are missing in the rest of their lives. I highly recommend reading his books: Teaching with Poverty in Mind: What Being Poor Does to Kids' Brains and What Schools Can Do about It and Teaching with the Brain in Mind. If you are a principle, the staff training sessions are very powerful!
