Abstract
Alexander, Schallert, and Reynolds's (Citation2009/this issue) what, where, who, and when framework situates different perspectives on learning in different places in this multidimensional space and by doing so helps us to better understand seemingly disparate approaches to learning. The framework is in need of a fifth, why dimension. The why dimension helps to place learning within an evolutionary and cultural perspective and to better understand students' motivation to learn and their preferences for what, where, and how to learn.
