It seems to me that transformational education is not easily defined because the construct brings together two words which are in themselves complex and difficult to define, especially in a short sentence. How can we know that the reader or listener is bringing together the relevant underlying suppositions we have in mind to create a meaning like ours?
Education is about change, growth, and development. What happens when we qualify this with a word that implies a radical change in form? Must transformational change be dramatic and cataclysmic? Can it be in fits and starts or even incremental? Does it mean a complete change in form or is something less all-encompassing also in view? These and many other questions are on our mind and leave us shy of anything that has the appearance of being a definitive and final one-sentence definition.
