I am very excited about this approach to learning/teaching mathematics! Neuroscience provides a user-friendly scaffold upon which we are able to more efficiently build our capacity to communicate vital principles and strategies therein. The concept of varying only what I want the learners to notice is very effective and simple! Furthermore, I used to think that examples were chosen in a slightly more random way, and that they had only to increase in complexity in order to properly illustrate the principle/strategy being taught. Now, I will more systematically chose the examples that I use in instruction, and so provide richer opportunities for the learners to explore the variable of focus, and it’s relationship to the concept as a whole.
