There were three informants involved in the in-depth interview of this study. The interviews were done in Indonesian to enable teachers to state their responses
more clearly even though some responses were answered precisely in English. The first interview was conducted for Inu on April 1, 2013 followed by Lilin on April 6,
2013 and the last was Anggi on April 9, 2013. The questions remained the same exploring teachers‟ background, professional coursework, contextual factor, and
classroom practice. The description of the interview questions can be seen in Appendix 1. From the interviews, two big classifications emerged, i.e. individual
beliefs and shared beliefs. Individual beliefs are these owned by each teacher differently meanwhile shared beliefs are those held by more than one teachers.
3.4.1.1 Construction of in-depth interview questions guideline
I prepared a list of interview questions guidelines based on the various theoretical sources. The questions were classified into four categories as stated in the
theoretical framework, i.e. schooling, professional coursework, contextual factor, and classroom practice. The schooling part covered information related to the experience
of the teachers who became the research participants when they became the learners of English. The schooling part identified the nature of a language and the benefit of
learning it. Furthermore, the professional coursework section contained information about the teachers‟ experience when they became teachers in relation to keeping their
professional development. Meanwhile, the contextual factor part presented perspectives which were not directly related to the teaching and learning process but
might influence the teachers‟ teaching practices. The last part, classroom practice
provided data on how the teachers implemented techniques in developing successful
learners‟ parameters. In conducting the interview, I used lists of questions as the guidance in throwing the questions to the informants and gave snowballing responses
toward the required clarification answers. The sample of questions is presented in Table 3.1 and the complete questions can be seen in Appendix 1.
Table 3.1 Sample of questions in the in-depth interview Category
Questions
Schooling How do you define a language?
How about the nature of English? Professional
coursework How do you teach effectively and efficiently?
How is the concept of learning in your classroom? Contextual factor
Have you ever been the participants of a teacher‟s forum? Classroom practice
How do you develop your students‟ communication skill? How do you develop your students‟ grammar
competence?
The questions were provided in Indonesian and I conducted the interview in Indonesian as well in order to ease the informants in giving the answers since even
though they are English teachers it is often difficult to express their mind in English. Considering the qualitative study with snowballing technique, not all lists of
prepared questions were rigorously used. They were adapted and adopted based on the situation so adding and omitting occurred if necessary. The adding actions were
done when I needed more clarifications toward the answers. Meanwhile, the omitting actions were done when the teachers already stated or implied the information which
was not asked yet.
