Intellectual or Academic Development?
Intellectual development can be fueled partially by academic development. The latter has been classically and is still largely focused on amassing knowledge, information and acquiring particular skills (reading, writing, math, scientific concepts and thinking, historical perspectives and such). Academic development is driven by standards-based curricula and test-taking. It is thus extrinsically motivated and driven by external goals. Academic development can lead to intellectual development of a specific kind — namely being exposed to ideas and concepts, remembering them and knowing specific skills. The intellectual development fostered by academic work is essential but it is not whole, not complete in how it enriches a mind. It is but one part. And, it is not personal or uniquely aligned to the intelligence in every unique learner.
This distinction is important and ever more so. Most schools focus on academic development and while it leads to a particular type of intellectual development, it should not be considered the whole of what a child's mind needs. Our education needs to focus more on intellectual development that is focused on broader cognitive skills, abstract thinking and also on the unique ways in which every child is truly intelligent. This is to say, every child is intelligent whether or not she is academically successful.
