77 Instruction Method. In First to fourth meetings, the narrative texts were spread out
to students and the analytical exposition texts were given to the students in the fifth to eight meetings. After the text were explained, the students were asked to
answer the questions related to the text individually because they taught without using cooperative learning Think-Pair-Share TPS method.
From the explanation above we can see that both of class had the same topics and material but different method of presentation. At the end of the
experiment, I conducted a post test for both of class in different day. I used the same test for both. For control group the test was conducted on November 20,
2012. For experimental group the test was conducted on November 23, 2012. The test results were used as the data in this study to determine whether there is
significant different in students’ reading achievement between experimental group and control group.
B. Data Description
The data described here are the result of the reading test. The description includes the mean, the mode, the median, the standard deviation and frequency
distribution followed by histogram and polygon. Based on the group analyzed, the descriptions of the data are divided into eight groups as follows:
1. The data of reading test of the students or the group who are taught by using Think Pair Share TPS A
1
2. The data of reading test of the students or the group who are taught by using Direct Instruction Method DIM A
2
. 3. The data of reading test of students or groups who have high motivation B
