I appreciate this article because it helps to dispel what you rightly call a myth. As Aristotle noted over two millennia ago, we are rational beings, and rationality includes both creative and analytical aspects. These are both components of what it is to be human. Thus, gearing our learning to encompass the entire person rather than segmenting it out into creative vs. analytical components seems the make sense to me.
As an example, I heard a presentation recently where the link between music and learning was discussed. A CAT scan of the brain of someone listening to music engaged the entire brain, not just one hemisphere of it. Of course, we all know from our own experience that including music can greatly enhance the learning experience and effectiveness for the learner. Hence, it follows that the best learning experiences engage the entirety of a person rather than attempting to segment it into an exclusively creative or analytical endeavor.
