1. Testing Requirement
a Normality Test
Normality test is done on two classes; those are experimental class and control class. Normality test is used to know whether the data
from both sample groups which is examined comes from the population of normal distribution or not.

The writer uses SPSS v.18 for Windows to do normality test which is Analyze-Descriptive
Statistic-Explore-Plots-Normality Plots with Tests, the steps as follows:
10
1 From the menu at the top of the screen click on Analyze then
Descriptive then Explore.
2
Move all of the data into the Dependent list
3
Under Display ensure that there is only a tick next to Plots.
4
Click on the Plots tab to open the plots dialogue box.
5 Under Boxplots click None, and remove any ticks under
Descriptive. Place a tick in Normality plots with tests. Under
Spread vs. Level tick none.
6
Click Continue, and then OK.
b Homogeneity Test
After normality test gives indication that data is distributed normally, so it needs to do homogeneity test. It is used to know the
similarity of the two conditions or population. If the significant value ρ 0.05, it means that the population has similarity.

The writer uses SPSS v.18 for Windows to do homogeneity test which is Analyze-
Compare Means- One Way ANOVA- Option- Homogeneity of Variance, the steps as follows:

1 From the menu at the top of the screen click on Analyze then
Compare Means then One-Way ANOVA
2 Move the data from experimental class into the Dependent list
and the data from control class into the Factor
3 Under Contrast and Post-Hoc ensure that there is a tick next to
Options.
4
Click on the Options tab to open the options dialogue box.
5
Place a tick in Homogeneity of variance tests.
6 Click Continue, and then OK.

c Specification of Interview
After conducting the research and getting the result. The writer does the interview to the selected students from the technique of
simple random sampling. This interview questions are related to what question that is needed to be asked, how to arrange the question, how
long the interview will be done, and how to formulate the questions.

Moreover, Patton explains the six kinds of question that can be an orientation in formulating the interview questions as follows:
1. The question which is related to the experience
2. The question which is related to the opinion or value
3. The question which is related to the feeling
4. The question about knowledge
5. The question which is related to the sensory perception
6. The question which is related to background or demography

G. Hypothesis Test
For hypothesis test, the writer uses t-test to find out whether there is significant difference between experimental class and control class in this study.
