A few months ago, I was talking with several people at a conference about my usual obsession with evidence-based work in learning. Part of my point was that there seemed to be a missing profession across education that is present elsewhere: an engineering complement to the science already available. An editor from the Chronicle of Higher Education was nice enough to suggest publishing the ideas in an op-ed, and so I did.
The key thing is that the natural world behaves the way it does whether we know the evidence about it or not. It's a shame not take into account our best possible understanding of what really goes on, when we're trying to build/do things at scale.
We're working hard at Kaplan to get more and more of our work tied in with what's known about learning - working hard at becoming a "learning engineering" education organization.
