Transfusions for mathematics teachers

Extract

We need occasionally to be fired by contact with better minds than our own, to observe excellent teaching and thinking to remind ourselves of what they are like. For such excellence is the ideal we all should seek. It is so easy to have one’s spark attenuated year by year by the dull monotony of ritual in a school’s monastic life—so that one hardly notices.
