I am most fortunate to have both Dr. Antoinette Minniti and Dr. Attila Szabo as my Directors of Studies. In the first five years, Dr. Szabo guided me all the way through the registration as MPhil/PhD student, successfully transferred to PhD studies and to the final stage of thesis submission. When I had a difficult time for the completion of this thesis, I was most fortunate to have Dr. Minniti stepped in and offered her assistance. Without both o f their unconditional support, it would be impossible for me to complete this work. May I take this opportunity to express my deepest appreciation to both of you. I would also like to thank my supervisors Dr. Clive Williams and Dr. Ellen Billet for their continuing support, help, guidance and patience. Appreciation also goes to Dr. Chris Slade from the Faculty o f Education at the Nottingham Trent University, for her valuable comments in response to my first year report in May, 2002. Thank you very much. I had wonderful support from my friends and colleagues at the Hong Kong Institute of Education with whom I have shared experience and have had the chance to discuss and share ideas. A special thank goes to Dr. Edward Chow for assisting me in the data analysis.I would also like to acknowledge those schools, principals and P.E. teachers for allowing me to collect data, their assistance were paramount in the completion of this study.Last, but not the least, I am highly indebted to my wife, Michelle, and my daughters, Natalie and Karen for their love, patience, and unending support throughout my programme of study.
