This research sought to understand the mental proof schemes that students possess, and to determine if these schemes progress when the Moore method is used in teaching a mathematics course. This study is significant in two major ways: First, it confirmed the mental schemes of proofs proposed by Harel & Sowder. Second, the study examined the effect of the Moore method on students’ learning and appreciation of proofs. Using a qualitative analysis design the study showed that the Moore method has positive affects on students’ conceptualization of mathematical proof, their self-confidence in their abilities, their appreciation of the relevance of proofs, and their ability to think autonomously. The Moore method allowed students to experience mathematics first hand. They built a coherent body of knowledge in which they created their own proofs. In memory of my mother Aminah and my father Yousef ACKNOWLEDGMENTS This dissertation could not have been written without Drs. Genevieve Davis and Michael Mikusa who not only served as my advisers but also encouraged and challenged me throughout this research project. They and Dr. Ulrike Vorhauer patiently guided me through the process, never accepting less than my best efforts, and for that I thank them. I would like to acknowledge the Foundation for the Advancement of Education and the Moore’s Legacy Project for the great resources they provided about R. L. Moore and his teaching method. This project would not have been possible without the help of John Neuzil for allowing me to collect the data from the course he taught. I am also thankful to the participants in this study --- Shannon, Ryan, Zack, and Chris. Their willingness to participate and donate their time was invaluable. My much gratitude and appreciation goes to my wife, Iktimal Alamin, for her support and encouragement. I am thankful for the moral support and encouragement that my sister Khadijeh and my brothers Yacoub and Yasin have provided throughout my educational career. In addition, I am thankful for the support of my close friend Waleed Abukhaled and the support and encouragement of fellow educator Paul Baiotto, M.A. iv TABLE OF CONTENTS Page ACKNOWLEDGMENTS ................................................................................................. iv LIST OF FIGURES ........................................................................................................... ix CHAPTER I.
