Professor Ken Robinson's underlying thesis is that our education system trains people for things which were important during the industrial revolution, but fails to train them in the most important skill for the 21st century -- creativity. The original book came out about ten years ago, which is when I first heard Robinson speak on the subject, and this revised edition is updated with experiences and ideas that came to him in the intervening years, many as a result of testing his ideas in the USA.
This is a hugely entertaining, warm and human book, and gains substantially from the additional perspective. Robinson's voice is infectious, and his self-deprecating and ironic style can catch you by surprise. This contributes greatly to the enjoyment you get from the book, and takes nothing away from the points he is making.
If you have never considered the issues of what education is for, and what it should be for, or of how creativity could be built into the system, this book will be a real eye-opener. If you've been wrestling with these issues for some time, then returning to Robinson in his revised form will be refreshing and bring new perspectives.
