D. Data Gathering Technique

In conducting this qualitative research, the researcher employed two major techniques to gather the data needed. The techniques were observation and interview. The interview was conducted twice. The first interview was conducted on February 4 th , 2010. The aim of the first interview was to get the information about what classroom language functions which were used by the Biology teacher. The second interview was conducted on April 1 st , 2010 and the aim was to get any data about the difficulties that the teacher had in applying classroom language functions in bilingual class. Both of the interviews were conducted after the teaching and learning activity so it did not disrupt the interviewee’s routines and the researcher had made a special appointment with the participant. Before conducting the interview, the researcher as the interviewer stated the purposes of this research and why the researcher chose biology teacher as the participant. The questions must be made as briefly as possible if no then the questions could bias the participant’s answer. The participants could give information as many as possible during the interview process and the questions given also could be added if it was needed. The result of the interview was recorded both in a MP3 player and also written down on the paper as a note. The data obtained in the interview I were used to answer the research question number 1, meanwhile, the result of interview II were used to answer second research question, which was the Biology teacher’s difficulties in applying classroom language functions in English. 34 As stated before, in order to complete the data, the researcher also conducted observations in X1 class until X6 class when there is a Biology class. The reason of why the researcher used observation as a data gathering technique is that because observation provides more objective information related to the research topic Hancock and Algozone, 2006.The results of the observations were transcribed in a form of observation sheets and fieldnotes which were used to support the data to answer the research problem. In this study, the researcher also employed video recorder during the observation. The purpose was to crosscheck the data obtained from the fieldnotes. Besides, it was also used to complete the data to make them more reliable. In addition, some points which were missed from the observation were added by watching the result of the video recording and vice versa. Related to that data completion process, there are some other benefits that the researcher may get since the researcher employed video recorder during the observation as stated by Marshall and Rossman 1989. They state that “research- filming is a powerful tool for inquiry into past events. Film has the unique ability to capture visible phenomena objectively”.
