Over the last twenty years the internet has increasingly been used in school settings as a vehicle for researching, presenting, discussing and delivering learning. While there are numerous technical type manuals about how to use the internet and best practice books written by experts, there are few publications that present rich and in depth case studies of teacher routine use. This book through its six case studies analyses what teachers think of, and how they use, the internet. A theoretical framework drawing on constructivist principles, community of practice concepts, and activity theory informs these cases. This book provides detailed examples of "real" practice in "routine" classroom settings and should be especially useful for school leaders as they develop plans to use ICT in their schools and for teachers who will implement these plans. Other teacher professionals including those in pre-service education should also find this book useful.
