This research was conducted in seven meetings with the presentation as follows, the first meeting was for the tryout test, the second meeting was for the pre-test,
the third, fourth, fifth, sixth meetings were for the treatment, and the seventh meeting was for doing the post-test and distributing questionnaire.
3.2 Population and Sample 3.2.1 Population

3.2.2 Sample
The samples were selected by using purposive sampling technique. Purposive Sampling technique is using knowledge of the study and the population to choose
participants. It is not random sampling that looks at the whole population. Purposive sampling is also called judgemental sampling and selective sampling.
This type of sampling results in group of responses that is not representative of the entire population, but instead represents a group that a specific characteristic in
common. Then, the samples were IXA and IXB. These classes were used by the researcher as experimental class. The researcher taught IXA by using KWL
Know, Want to know, Learned technique. Then, the researcher taught IXB by
using Jigsaw technique.
3.3 Variables
In order to assess the influence of treatments in this research, there were two kinds of variable, they are independent and dependent variables. Independent variable
was the major variable that a researcher hoped to investigate. Besides that, dependent variable was the variable that researcher observed and measured to
determine the effect of independent variable. The researcher proposed two variables in this research. They are as follows:
1. KWL Know, Want to know, Learned and Jigsaw techniques as
independent variables X. 2.
Reading skills as dependent variable Y.
