3.6.1. Scoring and Grading Pretest
Pretest is conducted at the beginning of the study. The students are given the reading comprehension test in the form of multiple choice tests which contains
reading comprehension passages and the questions according to the passages. The purpose of conducting pretest at the very beginning of the study is to measure
students’ readiness for further treatment of this study. The students’ score of pretest then is graded and analyzed statistically as starting
point in determining the result and effectiveness of this study.
3.6.2. Scoring and Grading Posttest
Posttest is conducted after both experimental group and control group received the intended treatment. The posttest is also in the form of multiple choice tests which
contains reading comprehension passages and the questions according to the passages
. The purpose of conducting the posttest is to measure students’ development after receiving the treatment.
Th e students’ posttest score then is compared with the pretest score and analyzed
statistically to determine whether or not there is the difference between the students’ total score before receiving the treatment and after receiving the
treatment in order to know which is more effective between Cooperative Integrated Reading and Composition CIRC and Jigsaw to teach recount text for
the 11
th
grader students of SMA N 1 Pegandon.

Method of Analyzing Data
In this study, the researcher analyzes the result of the experiment by using T-test. T-test is to determine if there is any significant difference in reading
comprehension mastery between the students who are taught and treated by using CIRC and the students who are treated by using JIGSAW in learning recount text.
According to the result of T-test calculation, if t-value is higher than t-table, it means that there is a significant difference in reading comprehension mastery
between both groups. On the other hand, if the t-value is lower than t-table, it means that there is no significant difference between both groups.
Before calculating T-test, the researcher needs to determine the mean, standard deviation, and variance for both experimental group and control group. The steps
in calculating and determining the result of T-test are discussed in the following:
