This book is authored during 2020 Pandemic-Lockdown when schools and colleges were closed, but education was open. Technology took charge and reached education to the doorsteps of students. Educational technology proved its point. The book is presented in a unique way of looking at educational technology to help teachers integrate technology based on the scientific principles of learning. Focusing on millions of teachers already in service who didn’t have a course on educational technology and the young teachers in preservice teacher education programmes, the volume is constructed into four tiers. The first tier comprises foundational learning—the Inheritance of Pedagogy; Introduction to Educational Technology; Understanding Self as A Teacher, The Science of Human Learning; Taxonomies of Educational Objectives; Communication Theories, Models and Practices, Instructional Design, etc. The second tier provides a profound learning experience on different pedagogical strategies, like Direct Instruction, Teaching Models, Programmed Instruction, Individualised Instruction, Differentiated Instruction, and Team Teaching. The third tier addresses technology integration in education with Flipped-Blended Learning Design, Online Education, Open and Distance Education, ICT Skills for Teachers, ICT Tools and New Technologies, and Models of Technology Integration in Education. The fourth tier deals with larger issues and implications, namely, What Research Says to Teachers, Comparative Policies and Strategy Frameworks for Educational Technology and Environment Building for Technology-Integrated Education. The leading scholars have commended the book as ‘an unprecedented contribution to the education community’, ‘a handbook of educational technology’.
