Recent years have seen extensive efforts in many countries to ensure that the right to educational opportunity is extended to all members of the community. As this has happened it has become increasingly apparent that traditional forms of schooling are no longer adequate for the task. Today’s pupils live in a world of remarkable interest and excitement. Many have opportunities to travel, whilst even those who do not are accustomed to a rich diet of stimulation through television, films and computers. In this sense they present challenges not faced by earlier generations of teachers. The pupils of today are, therefore, demanding and discriminating; they also, of course, bring to the classroom experiences and ideas that can provide important foundations upon which lessons can be planned.
