In past decade, the use of ICT in schools increased exponentially. However, ICT integration in teaching is still utilized at a low level. While many ICT professional development programs for teachers focus mainly on developing teachers' technical competency, the effect of their attitude, perception and emotion towards ICT integration is usually neglected. In this book, a social approach to professional development of ICT integration is argued to be important to improve ICT integration. A research was conducted to look at issues of ICT integration from the teachers' perspective and to explore the impact of peer support in enhancing ICT professional development. Based on the research findings, this book draws the focus on developing teachers' intrinsic motivation towards ICT integration. Peer support is found to be an enabler of intrinsic motivation. A sustainable peer support enhanced professional development model is thus developed. This book should help shed some light on developing ICT professional development programs for teachers and should be especially useful to teachers, professional developers and school leaders who want to lift ICT integration to a higher level.
