This book examines principles and strategies for use in achieving the successful mainstreaming (this book published in 1985 and since then the word 'mainstreaming' has been replaced by the phrase 'inclusive education') of students. The authors examine such things as principles for curriculum planning and the basic organisation and change that make inclusion work. Throughout the book, the basic questions of When does inclusion work? Why does it work? How does it work? have been asked. Numerous case examples illustrate the complexities involved in inclusion, the relationship of the process to the culture of schools and many other critical issues affecting the integration of regular and special education.
