CHAPTER IV RESEARCH FINDINGS
A. The Data Description
As the writer mentioned before, this study discussed about the effectiveness of using collaborative learning towards students’ ability in reading
descriptive text which has been done at the seventh grade students of SMP Pelita Harapan Jakarta. She held the teaching and applied the collaborative learning
approach in reading. She also gave pre-test and post-test to the students. After conducting the research, the writer obtained two kinds of data, the
scores of pre-test and post-test, as shown in the tables below.

Based on the table above, the writer obtained that there were 12 students who reached and passed the Minimum Mastery Criteria Kriteria Ketuntasan
Minimal. Meanwhile, 13 students did not reach it. The Minimum Mastery Criteria itself was 65. For those who reached the Minimum Mastery Criteria
meant that the students got score as same as the Minimum Mastery Criteria. For example, the students were on number 1, 8, 9, 10, 17, and 23. On the other side,
for those who passed the Minimum Mastery Criteria meant that the students got score higher than the Minimum Mastery Criteria. For example, the students were
on number 5, 6, 13, 15, 19, and 24. It can be seen that the highest score was 75. Meanwhile, for those who did not reach the Minimum Mastery Criteria meant that
the students got score lower than the Minimum Mastery Criteria. For example, the students were on number 2, 3, 4, 7, 11, 12, 14, 16, 18, 20, 21, 22, and 25. It can be
seen that the lowest score was 35.

Based on the table above, the writer obtained that there were 17 students who reached and passed the Minimum Mastery Criteria. Meanwhile, 8 students
did not reach it. For those who reached the Minimum Mastery Criteria were on number 3, 8, 9, and 25. On the other side, for those who passed the Minimum
Mastery Criteria were on number 1, 2, 5, 6, 10, 13, 15, 17, 18, 19, 20, 23, and 24. It can be seen that the highest score was 85. Meanwhile, for those who did not
reach the Minimum Mastery Criteria were on number 4, 7, 11, 12, 14, 16, 21, and 22. It can be seen that the lowest score was 40.
B. The Data Analysis
Data of students’ achievement in reading divided into two kinds, they are the data before they learn reading through collaborative learning which is gained
from pre-test and the data after they learn reading through collaborative learning which is gained from post-test. The writer presented
the data about the students’ achievement in reading both before and after using collaborative learning. The
first, the writer presented the result of pre-test, post-test, and its differences. Then, the writer used the formula statistic calculation of t-test with significance 5 to
decide significance of different results in reading before using collaborative learning and after using collaborative learning.
In the following table, the writer presented the calculation results of tests and its differneces to know the effectiveness of collaborative learning towards
students’ ability in reading.
