In this quasi-experimental study, there was Scientifics investigation which was done in manipulation on independent
variable.
63
In this study the researcher would use two classes to be tested. The first class would become the control group, and
another one would become the experimental group. The experimental group was conditioned to use flip learning
method, while the control group was using the habitual method used by the teacher.
Depend on statement of Asmadi, the experimentation was done to compare the two classes in which the control group
was generally taught by the conventional or usual procedure, and the experimental group was used the new method of
learning.
64
Both groups would be treated with the same procedure, and given pre-test and post-test before and after the
treatments with the same sets of the test. In this study, the researcher applied cluster sampling
technique by taking two classes in population. Afterward, the experimental and the control group were decided by the
researcher. The pre-test would be given to both groups to find out their ability in recount text before treatments. This would
be a measurement to both groups about how good they arrange sentences. Later, the researcher gave twice of treatments to
experimental group. The different classes would be taught in conventional method without EdPuzzle and the experimental
group would be taught by using EdPuzzle.
B. The Presence of the Researcher
In this study, the researcher played role as the teacher and data collector. The researcher gave the pre-test, treatment,
and the post-test, so she mixed up directly with the research object learners. She also was a full observer on the process of

E-learning implementation. In addition, this research had been known and permitted by the head master and the research
object.
C. Research Variable
In this experimental study, both of dependent variable and independent variable had clear dissimilarity. The
explanation about how the two kinds of variable associated one to another, there was a cause-effect relationship in experimental
study.
Dependent variable was the effect derived from treatments from EdPuzzle learning. Meanwhile, Independent
variable was similar to the cause which means that the media or the materials became the cause of the impact given after the
treatments.
65
It could be concluded that dependent variable was the effect on recount writing which appears after treatment
using EdPuzzle and independent variable was the EdPuzzle itself. In data analysis, the researcher would calculate the mean
and standard deviation to know about how effective EdPuzzle in use.
D. Population and Sample
1. Population
The population of this study was the learners on SMPN 1 Mojoanyar which was located on Jln Raya
Mojoanyar no.2 Mojoanyar. The school contact numberis was 0321 510062. For the details, there were four classes
for the entire class grade. In every class, there were 34 students. The classes which the researcher applied in the
research were two classes comprising VIII A and VIII B.

2. Sample
The samples of this research were two classes: VIII A and VIII B. The reason why the researcher take
those classes as a sample because both of those classes have resembled ability in English, this statement was taken
from the recommendation of the teacher on that school.
In addition, since this was a quasi-experimental research, the researcher used a purposive sampling. She
gave assignment to every eighth grade of the classes, and the results two classes ;VIII A and VIII B would be the
sample, both of the class have same total students; 34 students for each and they have resembled competence in
English. The researcher applied purposive sampling because he could not randomize the students to be the
sample in the population to represent in the study. The class would be separated into two groups, one would be
the experimental group, and another would be controller group.
