a. Class Average Score mean
Mean states the condition generally.

To get class average score, it used the following formula:
X̅ = Σx
n
Which X̅ : Class average score
x : Total Score n : Total student
By using that formula, it got the following class average score of post- action test 1:
X̅ = Σx
n X̅ =
= .

Subino, Konstruksi dan Analisis Tes Suatu Pengantar kepada Teori Tes dan pengukuran, Jakarta: P2LPTK, 1987, p. 79.
From the calculation above, it shows that class average score of post- action test 1 was 75.43.
b. Percentage of Post-action Test KKM
P = F
n x
Which P : Percentage of post-test KKM 1
F : Amount students who get score ≥ 75
n : Total students
It means: P =
x P = 68.57
From calculation above, it stated that percentage of post-test KKM 1 was 68.57
c. Improvement of Class Average Score from Pre-action Test to Post-action Test 1
X̅post test − X̅pre test = 75.43 – 65.14 = 10.29
1. Percentage of class average score from pre-action test to post-action test 1: P =
y − y y x
Which P1 = Percentage of improvement score from pre-test to
post-test 1 y1 = Class average score of post-test 1
y = Class average score of pre-test It means:
P = . − .
. x
= .
. x
= 15.79 From the calculation above, it shown that percentage of class average
score improvement from pre-action test to post-action test 1 was 15.79
4. Reflecting
In this phase, the researcher analyzed students’ achievement and progress
based on their test score got. In this phase, the researcher also discussed the result of the implementation of the modified action and decided whether the action
should be continued or not. From the data and observation, it could be seen that some students still got difficulties in elaborating specific information of a story to
the story mapping chart. Therefore, according to the discussion and the result of post-action test 1, the researcher decided that it was necessary to continue to the
second cycle because the researcher found only few students who got significant
progress.
Based on the result of previous cycle, the research must be continued to the next cycle Cycle 2 with doing some improvements, not only about the
students activities but also everything that supported the teaching learning process.
b. Cycle 2
