3.5.3 Interview

Interview was conducted to gain the secondary data collection method for this research. Interview can also be referred as a dialogue between an interviewer and the interviewee to get information needed. According to McMillan 1992:132, interview is a form of data collection in which questions ar e asked orally and the subjects’ responses are recorded. In this research, the interview was conducted with the eighth grade English teacher of SMPN 4 Jember to get the data about the way of teaching speaking at the school, the English text book used, and the teaching media which have been used by the teacher. Besides, a list of questions related to the data needed was prepared first as a guide during the process of the interview.

3.6 Data Analysis Methods

Having conducted the speaking post-test, the researcher analyzed the respondents’ speaking scores. The speaking scores were analyzed to find the mean difference between the experimental group taught speaking by using Board Games and the control group taught speaking without media, Board Games. It was analyzed statistically by using Independent Sample t-test on SPSS Statistical Program for Social Science with 5 significant level convidence interval 95. The procedures of applying Independent Sample t-test on SPSS to analyze the data were done as suggested by Lund and Lund 2012:1 as follows. a. Opening the SPSS program in the computer b. Setting the Variable View based on the data obtained c. Entering the data in Data View d. Selecting Analyze in toolbar menu, choosing Compare Mean afterwards and selecting Independent Sample t-test e. Resetting the Independent Sample t-test dialogue box to make sure the variable was put in the right way, entering the Post-test Scores into Test Variables box and the Group into Grouping Variable box, defining the grouping variable by setting 1 for the experimental group and 2 for the control group, then clicking Option to set the confidence interval into 95 and clicking continue f. Clicking OK to run the test g. Interpreting the result of the computerized test by looking at the Levene’s Test for Equality of variances column. This table was used to know whether or not the groups had score variability h. After reading Levene’s Test for Equality of Variances column, then the researcher had to look at the large column labeled t-test for equality means. Moreover, the formula of t-test is as follows: Notes : X 1 : Mean score of the experimental group X 2 : Mean score of the control group X 1 : Individual score deviation of the experimental group X 2 : Individual score deviation of the control group N 1 : The number of the respondents in the experimental group N 2 : The number of the respondents in the control group Christensen, 2006:415 t = X 1 - X 2 X 1 2 X 2 2 X 1 2 – + X 2 2 – N 1 N 2 N 1 + N 2 – 2 1 1 + N 1 N 2 40

CHAPTER IV. RESEARCH RESULTS AND DISCUSSION

This chapter presents the research activities including the teaching and learning process in both the experimental and control groups. The results of secondary data, the homogeneity analysis, and the try-out test are also revealed further. The primary data as the core of the research result are explained along with the data analyses which led to the hyphothesis verification. The discussion elaborates the explanation of the research result underlying the research.
