This notice holds great resonance for me as a teacher. I know I am guilty of this; pushing pupils through exams by teaching them exams and not the strength of enquiry. These days I pursue opportunities to divert away from exam questions and towards the world, finding it interesting. The sign is on a noticeboard in The Beanstalk, a nursery school my three children went to where I now teach ten year olds to prepare for selective entrance exams. Funny how the world turns around.
