The idea of "learn, unlearn, re-learn" begins with us. We have to unlearn our traditional methods of teaching and re-learn how to teach effectively in this new world. This will require great humility (i.e., teachable-ness), an acceptance of some trial-and-error in our approaches, and a consistent willingness to examine our practice, especially our errors, to learn through the process. I hear many schools claiming money as the biggest challenge. While I do not underestimate the influence of financial resources, I believe the more challenging obstacle may be ourselves and our willingness to become the learners in order that we may grow into effective teachers.
