4.2 The Data Analysis
Data analysis shows the analysis of the result of the activities given during the experimental research, both for the experimental group and the control group,
and also the t-test computation.
4.2.1 The Improvement of Students’ Writing Achievement
Treatment is needed in an experimental research and it is only given to the experimental group. It is usually used to make the students easier catching the
learning material, so they can improve their learning achievement. In this experimental research, the treatment was the use of the video clips as media for
teaching writing narrative text. There were two kinds of the video clips. They were video clips coming from Avril Lavigne and Emily Osment.
Then, the analysis was done to find out the improvement of students’ writing achievement after being taught writing narrative texts using video clips as media
and without using video clips as media. The analysis would be divided into two parts. The first part of the analysis was about the comparison between the total
score of the elements of good writing of the experimental group and the control group. The second part of the analysis was about the comparison between the
result of the pretest and the posttest on the elements of good writing of the experimental group.
4.2.1.1 The Comparison between the Total Score of the Elements of Good Writing
of the Experimental Group and the Control Group Based on the Boardman and Frydenberg’s essay evaluation 2002: 180, there are
five major elements of writing. They consist of content, organization, grammar,
53
word choice and mechanics. As a result, to find out the improvement of students’ writing achievement after being taught writing narrative texts using video clips as
media and without using video clips as media, the analysis was made based on the total score of the elements of good writing in the pretest and the posttest for the
experimental group and the control group. 4.2.1.1.1
The Pretest Results
Figure 4.1 The Column Chart for the Pretest Result of the Elements of Good Writing
The column chart above was about the pretest result of the elements of good writing. It showed that the total score of each element of good writing for the
experimental group was almost the same as the control group’s one like listed below:
1 Total score of content for the experimental group
: 658 Total score of content for the control group
: 644 2
Total score of organization for the experimental group : 658
54
Total score of organization for the control group : 637
3 Total score of grammar for the experimental group
: 589 Total score of grammar for the control group
: 591 4
Total score of word choice for the experimental group : 381 Total score of word choice for the control group
: 372 5
Total score of mechanics for the experimental group : 223 Total score of mechanics for the control group
: 225 It can be concluded that there was no significant difference and no
improvement between each aspect in both groups. In other words, the experimental group and the control group had the same quality in English subject,
especially in writing narrative texts. As a result, it was possible to do the experimental research in those groups.
4.2.1.1.2 The Posttest Results

Writing
The column chart above was about the posttest result of the elements of good writing. It showed that the total score of each element of good writing for the
experimental group was higher than the control group’s one like listed below: 1
Total score of content for the experimental group : 745
Total score of content for the control group : 714
2 Total score of organization for the experimental group : 737
Total score of organization for the control group : 681
3 Total score of grammar for the experimental group
: 666 Total score of grammar for the control group
: 635 4
Total score of word choice for the experimental group : 432 Total score of word choice for the control group
: 418 5
Total score of mechanics for the experimental group : 266 Total score of mechanics for the control group
: 246 The total score of content, organization, grammar, word choice and mechanics
for the experimental group was higher than the score of the control group. It means that there is an improvement in each element for both groups, but the
improvement of the experimental group is higher than the improvement of the control group. In other words, there is significant difference among each aspect.
