He has been my pillar, my hope, strength and joy throughout this process. Through his Grace, nothing in this study was too difficult to do and no deadlines too tight to meet. It is God Almighty's doing: In a space of four years, I am taking home this, Doctor of Philosophy (PhD) in mathematics education: a Master's degree in Research-Sociology and policy planning; and postgraduate certificate in mathematics education. But God works through people, I felt his presence through the unwavering support of: my spouse, Dalmas Menya and my three beautiful girls-Michelle, Gabrielle and Noelle; my parents, siblings and other family members; my church community; my Facebook fans, many of whom were my school friends in my early years of education; my newly found friends and colleagues from Sheffield Hallam University; my fellow commonwealth scholars; my supervisors, Prof Hilary Povey and Dr. Gill Adams-two ladies with hearts of gold and the best supervisors one could ever wish to have; and the noble participants, from the three schools where I carried out my field work. And He also works through institutions: through, Forum for African Women Educationists (FAWE) I was privileged to be nominated for the Commonwealth Scholarship and through the Commonwealth Scholarship Commission (CSC), I was honored to be awarded a full scholarship to undertake this study. It has been a beautiful journey, characterised by, persistence, prayers, cheers and hardly any tears. Galvanized by His Grace, we "rocked" this PhD, with a sole determination of using it as a tool for improving quality of mathematics education in my beloved continent Africa. Indeed, Africa is now one step closer to actualizing the vision of shaping a citizenry with demonstrable zeal, passion and prowess in mathematics.
