Six teachers participated in semi-structured interviews, which the researcher used to collect qualitative data (see Appendix F for more information). The researcher used teachers’ semi-structured interview to get data for research question 1 is to find out teachers’ perspectives on the coursebook’s evaluation in their course of teaching.
The aim of the interview was also to get data for research question 2, which was to opinions of teachers at private English centres on the suitability of the Everybody Up level 2’s package in terms of teaching speaking skills.
In order to get a good representation of the respondents' characteristics, the researcher purposefully selected the teacher participants based on their experiences with using the coursebook. For getting in-depth information and having an comfortable meetings, the interviews were conducted in Vietnamese which is the mother-tongue of the reasearcher and the teachers. The interviews were held via voice calling. The researcher conducted the interviews when the teachers had free time.
Each interview took approximately 20 minutes. The purpose of the semi-structured interview was to find some themes of the seeting of the study. By combining quantitative and qualitative data, this technique can enhance the conclusions.
According to Mackey and Gass (2005, p.173), a written list of questions as a guide,

including a freedom to survey, can be used to probe for more information in a semi- structured interview for the researcher.
There are two parts in the semi-structured interview. The first part was designed to collect teachers’ general information and teaching experience with the coursebook. The second part was designed with questions focusing on collecting data to clarify findings from research question 1 and answer research question 2. The semi- structured interview questions were presented in a table and were focused on the two research questions of the study. Research question 1 was expanded into 4 detailed questions relating to the findings of the questionnaires. Research question 2 was expanded into four detailed questions relating to the weaknesses explored in research question 1. The semi-structured interview questions and their aims are presented in the following table:
