had a significant progress. They improved their understanding of narrative text significantly.
Also they could do the task easier faster than before. The students’ participation also was observed
to know the students’ enthusiastic. In the end of this phase, the students were given the second post action
test. The following was a result of students’ score of post-action test 2.

X̅ = Σx
n
Which X̅ :Class average score
x : Total Score N : Total student
by using that formula, so it resulted the following class average score of post-test 2
X̅ = Σx
n X̅ =
= . From the calculation above, there was class average score of post-action
test 2. That was 82.57.
2. Persentage of KKM of Post-action Test 2
P = F
n x
which P : Percentage of post-test KKM 2
F : Amount students who get score ≥ 75
n : Total students So:
P = x
P = 91.43 From the calculation above, it stated that percentage of post-test KKM 2
was 91.43.
3. Class average score improvement from pre-test to post-test 2
X̅post test − X̅pre test = 82.57 – 65.14 = 17.43
Percentage of average score from pre-action test to post-action test 2 : P =
y − y y x
Which P2 : Percentage of average score improvement from pre-test
to post-test 2. y2 : Class average score of post-test 2.
y : Class average score of pre-test. It means that:
P = . – .
. x
= .
. x
= 26.75 From the calculation above, it stated that percentage of average score
improvement from pre-action test to post-action test 2 was 26.75.
4. Reflecting
Based on the results of cycle 2, showed that students’ progress was
significant. The researcher also discussed the result of the implementation of the modified action and decided whether the action should be continued or not. Based
on the observation which had been done in teaching narrative text by using story mapping method The students got easier to understand the text. So that way, the
researcher decided that the implementation of story mapping in teaching narrative was successful and the research could be ended.
B. Interpretation 1. Pre-action Class
The students were given some treatements before implementing Classroom Action Research. They were: Observation, questioner, interview and pre-action
test. Its aim is to know the condition of the students, classroom, also the teacher. Based on the data collected, it resulted some points. Generally, the condition was
not ready to do teaching learning process. It effected that teaching learning process was not effective. It could be shown on the result of pre action test which
class average score was only 65.14. Meanwhile, English KKM score is 75. It means that students were on the serious problem. They needed a special
treatement. Also, the result of observation sheet said that many students less motivativation of studying in the class. It may be caused by environment factor,
such as teacher, media also the technique used. The data above were got from the research before implementing CAR. It
was based on the Sugiono opinion in his book about the aim of research that methodological research basically is a scientific way to get the data for certain
purposes.

2. Cycle 1
In this cycle, all preparation were done. Such as; making lesson plan, time table, making teaching materials, preparing post-action test 1 form. It started
implement Classroom Action Research which using story mapping in teaching narrative text to improve the students’ understanding at second grade of MTs
Tarbiyatul Falah Bogor. There were some treatements applied in this step. To know the result of first cycle, it was applied questionnaire sheet also the students
were provided by post-action test 1. This was to measure the students’
achievement of first treatment. And the result said that there was an improvement of the students’ achievement of understanding narrative text. It was supportd by
the data gotten.

Sugiyono, Metode Penelitian Kuantitatif Kualitatif dan RD, Bandung: Alfabeta, 2008, p. 2.
The students could improve their score on post-action test 1. Based on the data that class average score was 75.43, which score was higher than before. It
means that there was an improvement for about 15.79. To make sure about the effectiveness of the technique and to maximize the result, so it was decided to
continue to the second cycle.
3. Cycle 2
In this cycle, the researcher did what he did in the first cycle. This steps is to strengthen the students’ achivement of understanding narrative text by using
story mapping. In this cycle, the students also were provided by post action test, which purpose to get the final result achivement. To show the result of the
research, here are some graphs of students’ achivement during implementing classroom action reserch in teaching narrative text by using story mapping.
It stated that class average score before implementing CAR was 65.14, and after implementing CAR it gets improvement. T
he students’ improvement of post- action test 1 was 75.43 and 82.57 of post action test 2. It indicates there was an
improvement of students’ achievement of English class. Its improvement was so significant, which in the first post-action test was 15.79 and the most
significant improvement was 26.75 of the second post test. Thus, the calculation of KKM improvement also occurs significant
changes. Before implementing CAR, the students who achieve KKM standard was only 22.86. It indicated there was
a serious problem of students’ achievement in English class. Based on the data, after applying story mapping of
teaching narrative text in the classroom, it resulted a significant improvement. It stated that 68.57 of the students who achieve KKM standard in the first cycle.
And the second cycle, the students who could achieve KKM was 91.43. Based on the graph above, it states that there is an improvement of KKM
percentage. It occurs after students are treated by teaching narrative text using story mapping. It means that using story map in teaching narrative text was an
effective way to improve the students’ English score, specially in reading skill.
