P = 23.81
From the calculation above, it is known the students’ percentage
score is 23.81. It means that there are ten students who passed the
Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM and there are thirty two students who still get the score below the Minimum
Mastery Criterion-Kriteria Ketuntasan Minimal KKM, from the percentage above, the writer gave the diagram
to show the students’ achievement in understanding simple present tense is very low. The
diagram as following:
After that, the researcher calculated the mean score of post-test I. To know the students’ score improvement from the pre-test to post-test I
result. It is calculated by using the formula: _ ∑x

─── 42
_ X = 72.74
From the calculation above, the students’ mean score of post-test I is 72.74. It means that there are some improvements in conducting the
action by using substitution rills. It could be seen from the pre-test mean score 55.95 to the post-test I mean score 72.74. So it can be concluded that
there is improvement of students’ score until 16.79 72.74 – 55.95. T
he next step is to get the percentage of students’ improvement score from pre-test to post-test I. The writer used the formula:
y1 - y P = ─── X 100
y
72.74 – 55.95
P = ──────── X 100 55.95
16.79 P = ──── X 100
55.95
P = 30.01
Based on the computation above, it could be seen that the percentage of the students’ improvement in understanding of simple
present tense from pre-test to post-test I is 30.01. It means that the score in cycle 1 has improved.
The last step is to get the percentage of students who pass the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM the
calculation by using the formula:
F P = ── X 100
N
30 P = ── X 100
42
P = 71.43
Based on the calculation above, it is showed the percentage of students who pass the Minimum Mastery Criterion-Kriteria Ketuntasan
Minimal KKM in post-test I is 71.43 . It is concluded the students’
improvement in post-test I who pass the Minimum Mastery Criterion- Kriteria Ketuntasan Minimal KKM is 47.62 71.43 - 23.81. It is
calculated there are twelve students who get the score below the standard of the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM.
The students’ score who pass the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM it could be seen from the diagram below:
After the researcher conducted cycle 2 of Classroom Action Research, she gave the post-test II to the students in order to know the
application of using substitution drills in teaching simple present tense successful and effective or not. The first step is the researcher to calculate
the mean score of the test in post-test II, it is used the formula: _ ∑x
X = ──
n
_ 3190 X =
─── 42
_ X = 75.95
From that calculation, the mean score of post-test II in the cycle 2
is 75.95. It showed that there are some
students’ improvement score 3.21 75.95
– 72.74 from the mean score of post-test in cycle 1.
The second step is to know the calculation of the percentage of students’ improvement score. The researcher used the formula:

P = ───────── X 100 55.95
20 P = ──── X 100
55.95
P = 35.75
From the computation above, it could be known that the students’ score in the post-test II in cycle 2 improves 11.94 35.75 - 23.81
from pre-test and 5.74 35.75 - 30.01 from the post-test I in cycle 1.
Then the next step is to calculate the perce ntage from the students’
score who pass the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM in post-test II. The researcher used the formula:
F P = ── X 100
N
38 P = ── X 100
42
P = 90.48
Based on absolute calculation above, it is known the percentage of students who pass the Minimum Mastery Criterion-Kriteria Ketuntasan
Minimal KKM is 90.48. It means that in cycle 2 there are thirty eight students who pass the Minimum Mastery Criterion-Kriteria Ketuntasan
Minimal KKM and there are only four students are below the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM. The class
percentage of post-test II obviously showed some improvements from the previous test, the improvement is 66.67 90.48 - 23.81 from the pre
test. The highest score in this post-test II is 100 and the lowest score is 40. The students’ score who pass the Minimum Mastery Criterion-Kriteria
Ketuntasan Minimal KKM and who still below the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM it can be seen in the
diagram below:
