As mentioned before, the research has been conducted at the three high schools in Haiphong city namely Thai Phien High School, Le Hong Phong High School (in the city) and Kien Thuy High School (in the countryside). At each school, the researcher chose randomly one 10th Grade class, in which the number of the students is fifty. Also, six to eight teachers of the English staff at those schools are also selected by chance in order to get the objective data. Among those teachers, some have had many years of teaching (more than 10 years); some others have just experienced teaching for few years. Therefore, the total participants of this study are 150 students of 10th Grade and 20 teachers at the three selected high schools in Haiphong city, both in the urban and rural areas. All the participants took part in the survey by responding to the two kinds of questionnaires, one for the students and one for the teachers. Besides, some teachers are also invited to take an informal interview so as to get a complete look into the research issues.
