This book is a result of research done in Morogoro region in Tanzania. The research was investigating practice of Professional development in Open and Distance learning programme under Adult education programme. The results shows that, there is professional development going on in form of meetings. The research results revealed that, this mode has not been effective. There is high need for professional development though means to meet those needs have been limited due to several problems. There has been several challenges facing practice of professional development in adult education centres. These include insufficient time, funds, readiness by teachers themselves, no permanent teachers, lack of clear goal during meetings and insufficient management commitment in the process. This is a good book for adult education practitioners as it gives experience of what is going on in the real environment of open and distance learning programme in adult education. It can be helpful as it has proposed new practice model for future Professional development. I recommend expert in education to use this experience in improving teaching and learning process.
