Despite the advent of the kindle and e-books, educational books are still best bought in paper. Here is my recommendation to support your own research and development.
An Ethic of Excellence
A superb book. Many schools are searching for that mystical jump from good to outstanding. In this book Ron Berger outlines how children are encouraged to explore projects and that the excellence/outstanding is a culture that is developed over many years. He used the collection of portfolios of examples of the very best work. These were then used each time a project was started. Examining these portfolios was an active process where the best features or characteristics were highlighted. Ron Berger shares these stories with a wonderful narrative voice that carries you easily through the text. Great book."...Drawing from his own remarkable experience as a veteran classroom teacher (still in the classroom), Ron Berger gives us a vision of educational reform that transcends standards, curriculum, and instructional strategies. He argues for a paradigm shift - a schoolwide embrace of an "ethic of excellence." A master carpenter as well as a gifted teacher, Berger is guided by a craftsman's passion for quality, describing what's possible when teachers, students, and parents commit to nothing less than the best. But Berger's not just idealistic, he's realistic - he tells exactly how this can be done, from the blackboard to the blacktop to the school boardroom....." from Amazon.co.uk
