The idea behind these Work It Out videos is so simple but so important. For so many years we have just assumed that students know how to use formulae and interpret diagrams. This is just not the case. Some complex abstract thinking is required to understand these techniques (not sure if this is the right word). This abstract thinking is hard to learn, and it is rarely taught.
