ABSTRACT
It was stated in the opening chapter that the basic idea which runs through this book is that change is more likely to be effective and justifiable when it is carefully planned with clear and reasonable pur poses in mind and when the curricula thus devised reflect what is practically possible and not just theoretically desirable. As new teachers come into the profession and as existing teachers learn more and develop new ideas, so educational practice is constantly changing. The changes which teachers seek to introduce into schools reflect their efforts to improve in some way the education they are offering to their pupils.
