The effectiveness of jigsaw technique in learning reading of exposition text: a quasi-experimental study at the second year students of SMAN 34 Jakarta.

The objective of the research was to see the effectiveness of Jigsaw technique in learning reading of exposition text at the second year students of SMAN 34 Jakarta and also to help the English teachers create interactive activities for students while learning reading of exposition text. The method applied in this research was quasi-experimental research. The quasi-experimental research design used was non-equivalent control group design. It means that there were two classes which one of them, the experimental class, was taught by using Jigsaw technique while the control class was taught without using of Jigsaw technique. Furthermore, this research was conducted through the following procedures: giving the pre-test, applying treatments, giving post-test. The data analyzed in this research were gathered through test. The result of the research proved that Jigsaw technique is effective to be used in learning reading of exposition text. According to the result of statistical calculation, it can be seen that the experimental class� mean of gain score is 4.74, and the control group�s mean of gain score is 4.23. Moreover, the analysis of the data shows that the t-observation (t0) is recorded at the score of 0.203 meanwhile the t-table (ttable) at 1% significance level is recorded at 2.376. It means that the tobservation (t0 = 0.203) is lower than t-table (ttable =2.376) which indicates that the effectiveness of Jigsaw Technique in learning reading exposition text has limited significance. The fact that the score of the t-observation is above 0 (zero) shows that Jigsaw technique had effectiveness when it was used and applied, although not a significant one, in learning reading exposition text
