This text discusses the theory and practice of several important areas of cross-curricular work in primary schools. It uses the National Curriculum Council's categories of themes, skills and dimensions to examine what is involved in such practice and to consider its current status in schools and future possibilities.; Providing practical suggestions for more well- established areas such as environmental studies, it also examines topical but under-represented themes, skills and dimensions such as media education, pupil self-assessment and discipline. The authors argue that cross-curricular practice both contributes to National Curriculum requirements and gives these requirements overall coherence. Cross- curricular practice also enables children to develop the knowledge, skills and concepts that are of value in coping with, and enjoying, the complexities of the 21st century. Suggestions are provided on how to provide leadership and stimulate staff interest in these areas by reviewing existing policies, teaching and resources.
