For the past 15 years of lecturing research methods in various universities in UK, South Africa, Kenya, Namibia, Tanzania, Ghana and other parts of the world the computing and informatics students always borrows text books from social studies or business. You could not get one which is purely written with expert from the field. This semester my class for research methodology in computing and informatics was having 780 students, and was not directly text book for them. Next year I have more than 1200 students, I would like them to have this book as a text book. It has been written for 4 yrs. More than 15 universities in Africa will directly have this book as text book in their libraries. I have been teaching in these universities, and this book is highly needed
