“Great teaching is the ability to distinguish between what can and needs to be explained and what cannot be explained. The working of a computer needs to be explained as it is made by the human mind. But a butterfly need not always be explained. A butterfly has to be seen with gleaming eyes of wonder as it is a natural expression of life and not of the mind. Great teaching is more like a craft than a technique. To evoke the curiosity in the learner, to care for the learner and to take the learner on a journey of discovery are some of the most critical elements of this craft.”
