ABSTRACT
In the three previous chapters, the important role of variation in opening up possibilities for a particular learning (or the development of certain capabilities) to take place was described and exemplified. We also illustrated that the way in which we experience or understand something depends on which features of it we are aware of and can discern simultaneously. Thus, when different aspects of the same thing are discerned and focused on, different ways of understanding will result. More powerful ways of understanding amount to a simultaneous awareness of those features that are critical to achieving certain aims.
