Recent changes in the content of some Secondary School courses in mathematics have been brought about chiefly to bridge a discontinuity which is often found between the mathematics presented to undergraduates and the examination requirements for sixth forms. It is mathematicians who have been the leading advocates of change at this stage. There has been no such pressure from Secondary Schools to Primary, though the discussions on new Secondary programmes have roused a considerable interest among Primary teachers and have already begun to influence the changes which are taking place in so many Primary Schools and at such great speed.
