This book is a collection of research work done in different parts of the worldwith one common goal – to enhance teaching and learning through technology. Content interaction and learning support are some of the key issues in the book. Many of the contributors worked together, so to speak, in cyber space as a result of technological advances. Many got to know one another through conferences we attended since the late 90’s. Many of the ideas in the book were presented at ICT2006 and ICT2007. The conference attracted about 300 researchers and practitioners around the world annually. One of the authors of Chapter One was indeed a keynote speaker from the conference.
