This is a book to make you think. Based on Steve Wheeler's blog of the same name, it includes topics like “measuring learning in the digital age”, a curriculum for the 21st century and digital identities. Although Wheeler is an academic, he is that rare bird, someone who writes in a way that is both engaging and understandable. This book will provide not only enjoyment in itself, but a wealth of topics to discuss with your students.
