1. Data Collection
There were six lecturers from English Department of Sanata Dharma University Yogyakarta to be interviewed for the investigation of this study. The classroom
instructions given by the lecturers who taught particular courses were the primary data for this study. The data were collected in the classroom when teaching-learning
process was underway by using recording techniques and notes. For the first step, the writer attended each class, one by one, those six lecturers
gave lecture. It started from the class of “Lecturer 1” who taught Introduction to English Test INTET, “Lecturer 2” who taught “English Structure” after that,
“Lecturer 3” who taught Stylistics, and then “Lecturer 4” who taught two different courses, which are Language Research Methodology and Pragmatics, followed by the
History of Modern Thought course taught by “Lecturer 5, and finally “Lecturer 6” who taught Interpreting. The process of gathering the whole data needed a couple of
weeks because the writer had to adjust to each lecturer’s teaching schedule in class. After finished doing the first step, which was attending each class, for the next
step, in each class where those lecturers gave the lecture, the writer used a voice recorder on the smart phone to record the interaction, such as explanations,
instructions, or conversations, each lecturer had in the classroom. The process of recording was done without the lecturers’ acknowledge. Besides, the writer was not
caught recording by the lecturers in the class. Therefore, the recording process went unnoticed by the lecturers. As the recorder on the smart phone recorded each
lecturer’s interaction with the students, the writer occasionally took notes on what the PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
lecturers said if there was any code-switching detected. The process of gathering the data in each class started since the class was begun until the class was over.
Furthermore, all the interactions each lecturer had in the classroom from the voice recorder were transformed into the script for the analysis.
As known, the process of gathering the data was not only from the classroom instructions, but also from the interview with the lecturers. The interview was done
by using interview techniques, recordings, and notes. The process of gathering the data from the interview was a bit different from gathering the data in the classroom
instructions, though the techniques were similar. For the first step, the writer made an appointment with each lecturer to be interviewed. Along with that, the writer
explained the topic of this study, so the lecturers knew why they were interviewed. As known, the interview was held mostly in the lecturers’ offices. Further, before the
interview began, the writer prepared the notes, a pen, and smart phone for recording the interview. When the interview started, the smart phone recorded the interview.
Meanwhile, the writer took notes on the lecturers’ answers. The questions asked to the lecturers in that interview were like, for example, “Why do you think about code-
switching in the classroom?” and “Why did you use it in class when you were lecturing?” As the interview finished, the data, especially from the voice recorder,
were transcribed into written form, into the script, for the analysis. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
