<p>
In the process of completing my graduation paper, I have received a
great deal of help, guidance and encouragement from teachers, friends and my
family.
First of all, I would like to express my sincere thank to Haiphong
Private University – an ideal environment, which gave me the chances to
learn and practice during the last 4 years.
Second, I would like to express my gratitude to my supervisor Mrs
Nguyen Thi Thuy Thu, M.A who has generously given me benefit of her
wisdom and varied experience in English teaching method and who made
valuable suggestions, careful detailed and critical comments. Without her
help, my research would have never been successfully completed.
Besides, my sincere thanks also are sent to other teachers of Foreign
Language Department, at Haiphong Private University for their valuable
lectures and instructions during the 4 years which helped me much in
completing my research. I also would like to send my thank to teachers and
students at Hai Phong Popodoo English School where I’m working in for
giving me endless support and stimulating encouragement as well as helping
me fulfill the survey questionnaires.
