This study would not have existed without help, encouragement and cooperation of many people. My family, my friends, my colleagues, my professors and many others whom I cannot mentioned have helped me a lot in different ways to finish this research. After the almighty Allah, and with deepest appreciation, I would like to thank Dr. Mohammad Al Rasheed, the Former Minister of Education in Saudi Arabia who gave me the opportunity to pursue my higher education in the USA. I am indebted to Dr. Al Rasheed to help bring my dream into reality. I would like also to thank Dr. Rabea Jan, the Chairman of Computer Department at Jeddah Teacher College for his belief in me. Rebea means Spring in Arabic and Professor Rabea is like spring in his care, help, and passionate. Both Dr. Al Rasheed and Jan have a great impact on my life.
