From observing the participant of the students, it can be concluded that by using Pictures, the students more understand and enjoy in teaching vocabulary.
They are motivated to be active in teaching learning process.
3. Result of Post Test
Before the students did the test, the writer had done pre test, difficulty item, validity of test. The result of post test as follow:
a. Result of Post Test I in the First Cycle
To know the students‟ improvement in first cycle, the writer evaluated them by giving a post
–test in the last cycle I. the post-test accomplished on Tuesday 1 march 2011. There were 29 students who follow in this test. This post-
test during 30 minutes. There are 20 multiple choices items given by the writer. The score was that 3 students got 60; 5 students got 65; 6 students got 70; 12
students got 75, 2 students got 80.
The result of the post –test I can be seen in table below.

Based on the result of the post-test I, showed that the mean score of post- test I was 70, 86. The highest achievement gained score 80, and the lowest
achievement gained score 60. It can be concluded that the students‟ achievement of vocabulary improved from pre-test. Therefore, the observer must continue to
the next cycle because the students could not achieve yet the standard of the Classroom Action Research CAR 75 of the Minimum Mastery Criterion
– Kriteria Ketuntasan Mastery KKM 65.

b. Result of Post test II in the second Cycle
The teacher was evaluated by giving a post-test II after the second cycle had finished in using teaching vocabulary through pictures. It was conducted on
Tuesday, 15 March 2011. The observer reviewed again all the materials given during those cycles by performing some activities and asking by giving some
pictures the students to guess them. In the post-test II, there were 20 items that were similar with pre-test and post-test I.
The result of the post-test II in the second cycle can be seen in table below:

Based on the result above the observer and the writer stopped to the next cycle, because the students could achieve the standard of criteria action success
was 75. The observer describe the students‟ vocabulary score in pre-test,
post test I in the first cycle and post test II in the second cycle in the table. Furthermore the observer used quantitative descriptive technique to analyze the

The students who passed the Minimum Mastery Criterion –Kriteria
Ketuntasan Minimal KKM 65
To analyze all data, the observer would calculate the students mean score of the test, calculate the class percentage, and calcu
late the students‟ improvement score from pre-test to post-test I up to post-test II into percentage.
The first step in analyze the data of pre-test is to get the mean score of the test. It is calculated by using this formula:
Σ
x X =
n
1815 X =
29 X = 62.58
Based on that calculation, it is showed the mean score of the pre-test was 62,85. It means that the students‟ vocabulary mean score of pre-test before
implementing Classroom Action Research CAR or before using pictures in teaching vocabulary was 62,85.
Next step is the percentage of students‟ score who pass the Minimum Mastery Criterion- Kriteria Ketuntasan Minimal KKM in pre-test used the
formula as follow: F
P = X 100
N
15 P =
X 100 29
P = 51.72
From the calculation above, it is known the students‟ percentage score is
51.72
it means that there are 15 students‟ who passed the Minimum Mastery Criterion- Kriteria Ketuntasan Minimal KKM
and there are 14 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 to show the students‟ achievement in understanding Vocabulary is still low. The
diagram as
following:
After that, the researcher calculated the result of post-test in cycle 1 to know the students‟ score improvement from the pre-test 1 result. The first step is
calculating the mean score of post-test 1. It is calculated by using formula:
Σ
x X =
n
2055 X =
29 X = 70.86
From the computation above, the students‟ mean score of post-test in
cycle 1 is 70.86. it means that there are some improvements in conducting the action by using Vocabulary. It could be seen from the pre-test mean score 62.58
to the post-test 1 mean score 70.86. So it can be concluded that there is improvement of students‟ score until 8.28 70.86 – 62.58.

The next step is to get the percentage of students‟ improvement score from pre-test to post-tes1. The writer used the formula:
y1 - y P =
X 100 y
70.86 – 62.58
P = X 100
62.58
8.28 P =
X 100 62.58
P = 13.23
Based on the computation above, it could be seen that the percentage of the students‟ improvement in understanding of Vocabulary from pre-test to
post-test1 is 13.23. it means that the score in cycle 1 has improved therefore;
the writer must conduct the post-test 2 in the second cycle, because it still need
more improvement to achieve the target of Classroom Action Research 75.
Finally, 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
26 P =
X 100 29
P = 89.65
Based on the absolute numerical above, it is showed the percentage of students‟ who pass the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal
KKM in post-test 1 is 89.65.
It is concluded the students‟ improvement in post-test 1 who pass the Minimum Mastery Criterion-Kriteria Ketuntasan
Minimal KKM is 1.73 89.65 - 51.72. it is calculated ther are twenty six
students‟ who pass the KKM and ther are three students who get the score below the standard of Minimum Mastery Criterion-Kriteria Ketuntasan Minimal KKM.
Even though it is still needed more improvement because it could not achieve yet 75 as the target of success Clasroom Action Res
earch CAR. The students‟ score who pass the Minimum Mastery Criterion-Kriteria Ketuntasan Minimal
KKM, it could be seen from the diagram below:
After the writer conducted cycle two of Classroom Action Research, she gave to the students‟ a test in order to know and to prove whether the
application of using pictures teaching Vocabulary successful and effective or not either from the result of pre-test or post-test 1. There are three steps to know this

improvement. Those are: first step is to calculate the mean score of test in post- test 2, it is used the formula:
Σ

2460 X =

X =84.82 From that calculation, the mean score of post-test 2 in the cycle 2 is 13.96
84.82 – 70.86 from the mean score of post-test in cycle 1.
