Another important support for chang

Another important support for change was the use of outside experts, withan example being given of one Japanese expert pressing teachers to includestudents’ anticipated solutions in their lesson plans, to consider how many suchsolutions were likely, to think about how they would treat incorrect solutions(Perry & Lewis, 2009). Our own experience at the international conferencereferred to earlier (Doig et al., 2009) showed that participants were themselvesonly able to find a couple of possible solutions and were sceptical that the grade3 students would be able to come up with different solutions to the problem ofdividing three pizzas equally between four people. The five children whoparticipated the following day in fact found 16 mostly different solutions.
