A great introduction to mindset from Jo Boaler.

Mindset is incredibly important for kids with disabilities in mathematics.  Too often, kids with disabilities are given the impression that they lack the ability to do complex mathematics.  And, perversely, when kids are labeled LD, they are often told that they are “smart” but their brains are not “wired” to read easily, or do mathematics easily.  In this sense, we are constructing fixed mindsets for kids.  We tell them that kids with LD are smart, and that their abilities in some areas are fixed at a high level, and their abilities in other areas are fixed at a low level. When we know how destructive fixed ability mindsets can be, why do we purposely create them in kids with LD?
