This article addresses how mentoring can move the student teachers' process of learning towards constructive teaching forms. An underlying assumption of such an approach is the need to understand what pupils know and say. The focus in the article is on how Sara, a cooperating teacher in Norway, encourages student teachers to start their student teaching by developing a mindset where seeing the kids is in focus. She does so by designing and taking care of natural learning situations, and by assisting them to develop their habit of seeing through their own teaching.
