analyze students’ improvement. The first step is calculating the mean score of post-test 1. The calculation is as follow:
X = Σx
N X = 1065
15 X = 71
The data above showed that mean of s tudents’ score in post-test 1 was 71. It
means that there were some improvements in the mean score of post-test 1. Therefore, me
an of students’ score from pre-test to post-test was improved 10.67 point, 71
—60.33. The next step is identifying the percentage of students who pass the KKM.
The calculation is as follow: P = F x 100
N P = 6 x 100
15 P = 40
From the calculation above showed that the class percentage which passed the KKM was 40. In other word, there were 6 students who passed the KKM and 9
students who get score below the KKM. It can be interpreted that there was improvement from the class percentage of pre-test and post-test 1. The data
showed that the improvement was 26.67, 40 —13.33.
Then, in Cycle 2 of Classroom Action Research by using STAD Technique, the researcher also calculates the result of post-test 2 in order to know the score
improvement between post-test 1 and post-test 2. Three steps used in this calculation. The first step is analyzing the mean score of the class in the post-test
2. The calculation is as follow: X = Σx
N
X = 1215 15
X = 81 The result above showed the mean score of the class in post-test 2 was 80. It
means, the mean score in post-test 2 increase 9 point since in the post-test 1 the mean score of the class is 71.
The next step is identifying the percentage of students who passed the KKM. The calculation is as follow:
P = F x 100 N
P = 13 x 100 15
P = 86.66 The data above showed the percentage of students who passed the KKM was
86.66. In other word, there are 13 students who passed the KKM, and only 2 students below the KKM. It can be interpreted that the class percentage of post-
test 2 obviously increased from the previous test. The improvement is 73.33 from the pre-test and 46.66 from the class percentage of post-test 2.
B. Interpretation of the Result
As whole of the calculating above, the interpretation of the data result among pre-test, post-test 1 and post-test2 as follow:
In the pre-test, the mean score of the class on reading test before implementing Classroom Action Research CAR was 60.33. In ot
her word, it was the students’ reading score before the teacher used Students Team Achievement STAD
Technique in learning reading. In addition, the percentage of students who passed the KKM was 13.33. It means from 15 students in the class, there were only two
students who passed the KKM of English lesson 75 . Meanwhile, in the post-test 1, the mean score of the class was 71. It means
there was improvement in the cycle 1 of applying Classroom Action research using STAD technique. The mean score of the class increase up to 10.67 from
the previous test. Further, the percentage of the students passing the KKM was 40. In other word, there are 6 students passed the KKM in the post-test 1.
Therefore, it can be interpreted that after applying STAD technique in learning reading discussion text, the mean score and the percentage of the students who
passed the KKM was improved. However, the improvement had not achieved the target yet, that was 85 of students had to pass the KKM. Hence, the researcher
decided to continue to the second cycle. In the second cycle, the mean score of the class was 81. Then, the percentage
of students who passed the KKM was 86.66. In other word, there were some improvements either in the mean score or in the percentage of students who
passed the KKM. The mean score improve 13 point from post-test 1, that was 71. Additionally, the students who passed the KKM increased significantly to 13
students and only 2 students who got score below KKM. In short, the class percentage showed the improvement 46.66 86.66
—40 from post-test 1. It was in line with the result of the questionnaire that showed 79.30 of students
were respond the action positively. Besides that, the result of post-questionnaire show the improvement compared with the result of the questionnaire before CAR,
they were 51.97 of students who respond the action positively. In conclusion, based on the calculation above, it could be interpreted that post-test 2 in the
applying CAR by using STAD technique was success. It was proved from the percentage of students who passed the KKM score was 86.66, and it has already
met the criterion of success 85 which means this cycle did not have to be continued to the next cycle.
This research discovered how student responded to Student Teams Achievement Division STAD technique. They stated that the technique was very
useful and the process of teaching and learning as well as reading activities were enjoyable. They believed that the use of STAD technique could improve their
reading comprehension, especially when they read discussion text.

CHAPTER V CONCLUSION AND SUGGESTION
After finishing the whole steps of this Classroom Action Research CAR study, it can be drawn some conclusions considering the result of this research.
Furthermore, related to the conclusion, there are also some suggestions given.
A. Conclusion
This subtitle presents the answer of the questions which have written at the formulation of problem in the previous chapter. Based on the result of the research
that was conducted in the XII
th
grade students of science class at SMA Fatahillah in academic year 20142015, it can be drawn conclusions as follows:
1. The students could improve their reading comprehension of discussion text through Students Team Achievement Division STAD technique in two
cycles. 2.
The students’ score in reading comprehension of discussion text improve significantly through STAD technique. The data showed 86.66 of the
students in the class passed the KKM which was used as indicator of students’
success. In short, the score of students’ quality in learning reading have good
level.
B. Suggestion
Based on the conclusion above, it can be delivered some suggestions, go to: 1. The teacher, STAD technique
would be helpful to develop students’ reading comprehension in learning discussion text. Therefore, the teacher needs to
maintain using STAD technique in the next new academic year in teaching discussion text and another type of texts.
2. The suggestion for students is about the activeness of the students during the reading lesson. They must actively involve in the lesson, so they know what
they learn and how to implement what they have learn.
