refers to representative of the total students chosen from the population in which the researcher judges that they provide the data needed. In this research, the
researcher believed that they were able to give the data needed to the researcher to complete the data.
D. Instruments and Data Gathering Technique
In this research, there were two instruments to collect the data from the students. Those two instruments were used to obtain the data were questionnaire
and interview as follow.
1. Questionnaire
Questionnaire is one of data gathering instruments in which the respondents answer several questions or respond in the form of writing
Best Kahn, 1986. From the statement, it can be seen that instrument is an important role in a research in order to obtain the data from the students.
Questionnaire is divided into two types, close-ended and open-ended. According to Ary, Jacobs, Sorensen 2010 open-ended questions are used where
the researcher want to know deeper about the questions. It allows the individual more freedom of response because certain feeling or information may be revealed.
While, close-ended questions are used when the researcher hopes for specific answer and the possible responses is limited.
In this research, the researcher used close-ended questionnaire. There were 22 close-ended questions and 2 open-ended questions in the questionnaire. In this
research, the researcher used likert scale in the questionnaire. Likert scale is a scale with a number of points that provide ordinal scale measurement
35
Wiersma, 1995. There are some likert types can be used by the researcher. Ary, Jacobs, Razavieh 2002 state
“likert-type items let subjects indicate their responses to selected statements on a continuum, from strongly agree to strongly
disagree.” The researcher chose five levels from strongly agree, agree, neutral, disagree, and strongly disagree. Please see Appendix 3.

2. Interview
In this research, an interview was used to complete the data from the questionnaire. According to Best and Kahn 1986, interview is like an oral
questionnaire. Interview provides opportunity to in-depth information and clarifies unclear answers Wiersma, 1995. In this research, the interview result was used
to clarify and strengthen the students‟ responses in the questionnaire. Based on Ary et al. 2002, there are two types of interview: structured and
unstructured. The researcher used structured interview in order to get structured data or ordered data needed. The researcher took six students out of sixty-eight
students to be interviewed from the same respondents. The researcher chose three students who had positive response and three students who had negative response
toward the implementation of the weekly public speaking. Based on Wiersma 1995, the researcher recorded the interview and then typed the
recording between the researcher and the students since tape recorder can retain
36
the entire oral communication. The result of the raw data of open-ended questions was put in the appendix. Please see Appendix 6.
