Research Method Method and Design of the Research

validity test of post-test, there were 26 valid questions from 30 questions which were gained. Based on the standard of reliability test, 0.4-0.59 means the reliability of the test was medium, meanwhile 0.6-0.79 means the reliability of the test was strong, and 0.8-1.0 means the reliability of the test was very strong. In this research, the score of reliability test of pre-test was 0.8 which means that the reliability of pre-test was very strong, meanwhile the score of reliability test of post-test was 0.66 which means the reliability of post-test was strong.

E. Data Collection Technique

Technique of collecting data in this research was pretest and posttest that was given to both experimental class and control class. In this research, the researcher gave pre- test to see students’ basic capability in reading before using Question Generation Strategy in reading class. The next test was post-test which measured the difference of the students’ score between the experimental class and control class after given the treatment.

F. Data Analysis Technique

The researcher used statistical calculation to find out the differences between students’ score in experimental class 8B which was taught using Question Generation Strategy with students’ score in control class 8A which was taught using silent reading method. In this research, there are four tests which were calculated; normality test and homogeneity test, hypothesis test, and effect size test.

1. Normality Test

Normality test was done in both classes; the experiment class and control class. Normality Test was used to know whether the data from the sample group which was examined comes from the population of normal distribution or not. The normality test was calculated using Kolmogorov-Smirnov technique with requirement as follows: - If the significance scores of Asyim Sig 2 tailed 0.05, the data came from the normal population
