Education in Africa has a lot of issues of concern. The quality of education due to large numbers of pupils in class is one of the concerns. This book unveils some of the issues dealing with theory and applications involving large classes in African schools, particularly, in Kenya. My sincere gratitude goes to my supervisor who encouraged me to write this book. Through his supervision, advice and fair critique, I was able to draft this document. I will always be indebted to him for his support and friendship. It has not been easy but the constant support you accorded me propelled me to this extent. Be blessed always. The text is a research based text and is very interesting to general readers and researchers alike.
