their speaking. The process of the treatment would be explained further in the Chapter IV using the result of the research
er’s field notes see Appendix 10.
5. Conducting the Post-test
After conducting the pre-test, the researcher gave treatment to the students. The treatment was done by implementing Scientific Approach in KTSP. The final
result of the treatment was measured by post-test. Similar to the pre-test, the students had to make a persuasive speech to persuade their friends on the theme
“students shouldshould not smoke in school area”. The post-test was assessed by using the same rubric used to assess the pre-test see Appendix 6.
F. Data Analysis Technique
In this study, the researcher used 5 steps on the data gathering technique, which were questionnaire, FGD, pre-test, and post-test, and field notes.
1. Questionnaire
The questionnaire in this study is used a likert scale Ary, Jacob, Sorensen, 2006 which is also used by Ferianda, 2013 in his thesis. A likert scale
is a topic in a form of statement and the respondent should choose whether they strongly agree, agree, disagree, or strongly disagree. The scoring technique will be
presented on the following table:

Table 3.4 Scoring Grade for Questionnaire
To find out the choices of the respondents, they had to circle the answer. The researcher had calculated the results and presents it in a form of percentage with
the formula below:
x100
X: the total number of students based on the degree of agreement
n
: the number of all students
2. Statistical Hypotheses
The researcher collected the scores of the pre-test and the post-test as the data of the research. The data was calculated manually by using formula of the
paired sample t-test Supranto, 2009. First, the researcher would calculate the standard deviation with formula:
Ho: the mean score of post-test is equal or less than the mean score of pre-test Ha: the mean score of post-test higher than the mean score of the pre-test
Ho is refused if t ≥ t table; α: 0.05.
