CHAPTER 3. RESEARCH METHODOLOGY

This chapter discusses the research methods applied in this research. It covers research design, area determination method, respondent determination method, operational definition of the terms, data collection method, and data analysis method.

3.1 Research Design

The design of this study was quasi experimental research. This design used two classes taken from the whole population randomly based on the result of the homogeneity test. The first class was used as the experimental group and the second class was used as the control group. In this research, the experimental group was given treatment, in which the students were taught grammar, especially tenses, using NHT technique, while the control group did not receive any treatment using NHT technique, but the group was taught through lecturing technique. Afterwards, both classes were given post-test. The result of the post-test was analyzed using t-Test formula. The research design can be illustrated as follows: Group Treatment Posttest A X O B O A : The Experimental Group B : The Control Group X : The treatments - : No treatment O : Post-test for both the experimental and control groups McMillan 2006:175 http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id http:digilib.unej.ac.id The procedures of the research activities were as follows. 1. Administering the homogeneity test to the population all of the seventh year students of SMPN 2 Balung, Jember, in the 20112012 academic year. 2. Determining the two groups that will be used as the experimental group and the other one as the control group. Based on the result of the homogeneity test analyzed using ANOVA, it was known that the result of „f ‟ was higher than that of the F table. That meant that the population was heterogeneous. Therefore, the researcher needed to take two classes which had the nearest mean score. Class VII C and VII B were chosen as the experimental and the control classes respectively because both classes had the nearest mean score. 3. Constructing Lesson Plans for the experimental and control groups. 4. Conducting the treatment, that was, teaching tenses using NHT technique to the experimental group, while the control group was taught tenses using lecturing technique. 5. Administering the post-test to the experimental and control groups. 6. Analyzing the collected data from the post-test using t-test formula to know whether or not there was a significant effect of NHT technique on students‟ tense mastery achievement. 7. Drawing a conclusion based on the data analysis to answer the research problem.
