This book is based on the syllabus of the 2-year B.Ed Programme designed by Kerala, Calicut, and Mahatma Gandhi Universities of Kerala State. It is hoped that this book would be equally helpful to prospective teachers of teacher education institutions and to the teachers in pre-service and in-service training in the teaching-learning scenario. It will also help practising teachers and teacher-educators to update their knowledge and deal with context-based understanding and analysis of their classroom experiences. The author has tried to provide some basic ideas and strategies to help teachers in the development of concepts in Educational Technology among their students and hopes that this book will serve the purpose of teacher education programmes.
