Instrument and Data Gathering Technique

26 learning teaching activities. It means that the student teacher shows the interest in teaching. The neutral influence means that there are three effect of motivation but the student teacher is not really sure whether shehe will become a teacher or not. The negative influence means that there is no effect of motivation shown during the teaching practices. After the data were collected, the researcher analysed the data. The data were analysed using coding. According to Moleong 2013, coding is a process to make the categorization and to describe the implication and the details from each category. It was done in four steps: 1. The interview data which were in the form of recordings were transcribed into a written form in three columns. The first column was the original speech. It consisted of the questions from the researcher as the interviewer, and the answers of the student teachers as the participants. In this part, the researcher transcribed every single word given by the participants. 2. The researcher made the first coding in the second column. The first coding summarized the information given by the participants. 3. In the last column, the researcher made the categorization of the first coding. The categorization was made based on the points related to the problems in this study. 4. The categories from the coding then were classified based on the research problems. They were combined with the findings from the classroom observation data. The categories were used to describe the finding in chapter IV. 27 In order to establish the trustworthiness of this study, the researcher used the triangulation. Guion 2002 stated that triangulation is a method used by qualitative research to check and establish validity of the study. This study used the data triangulation which involved the use of different sources of data or information. The sources of data used in this study were the classroom observation, the student teachers as the participants in the interview, the researcher who interpreted the data, and the supervisor of this study who gave advice for the data analysis. After gathering the data from the classroom observations, the researcher conducted the interview. This interview was aimed to gain the insight on what has been found in the classroom observations. After finding the same data from the two sources, the researcher consulted the findings to the supervisor. By involving these sources of data, the validity of this research was established. The researcher made some tables to classify the findings based on the categorization. The first classification was about the productive and disruptive student s’ behaviours based on the theory of Ormrod 2011, Browne 2012, Kuhlenschmidt and Layne 1999, and Aly and Gracey 2013. Table 3.2 shows the classification of the student productive behaviours in the classroom.
