In my exploring of knowledge and in the course of completing my dissertation,
many individuals have assisted me. I would like to acknowledge wholeheartedly their
assistance, cooperation, and encouragement which all contributed in making this study
possible. Without them, this study would not have been completed.
First, my sincere appreciation goes to Dr. Saengchan Hemchua my advisor. She
has guided me through the completion of the doctoral program and through this
dissertation. Dr. Hemchua always listened to me patiently and carefully, and challenged
me to think critically. She has constantly provided me with encouragement and support. It
is an honor for a student like me to have had Dr. Hemchua as an advisor during my
research and a role model for my forthcoming teaching profession.
My sincere gratitude also goes to my research committee, Dr U-maporn
Kardkranklai and Dr. Walaiporn Chaya, for their professional and insightful comments
and for trusting my capacity as a researcher and my responsibility. Their guidance kept
me alive throughout the ongoing research. They gave me a lot of recommendations and
an invaluable feedback to my qualified work. As my appreciation, my respectful heart
goes with them forever.
I also wish to thank Dr. Ubon Dhanesschaiyakupta and Dr. Saiwaroon
Chumpavan for their insightful comments which they kindly shared as external members
of the committee.
Appreciation is extended to the Foreign Language Department at Nuannordit
School for their permission to conduct this study. I am also indebted to the teachers and
students participating in this study. Without their patience, cooperation, and attention to
this investigation into new knowledge, this study could never have been completed.
