Tenth Graders of Jordanian Male Students. The used two groups, a privete school as the controlled group and the public school as the experimental group. To
administered tha data, the writer conducted pretest and postest. The data were analyzed by using mean score. The result was the public school score higher than
private school. In other word, KWL was efectif in improving reading comprehension performance.
Furtheromre, the distinguishable point in this reserach is that this research was the material used as the variable. The writer decided to use the descriptive
text. The main reason was there was many things that could be describe such as animal, person and thing. In addition, it also could explain about feeling and
sense. So, the students esier to recall their prior knowledge because they had more information about the topis.
E. Conceptual Framework
Reading is one of language skills that students need to be acquire because reading may improve and develop their knowledge and their language skill. When
students read a text, they have to comprehend and intrepet the ideas from the text, so they may get the information and message from the writer.
Unfortunatelly, most of students have many problems in their reading compeehension. Here are the five main problem that usually found by students. 1
Students have diffuculty with the meaning of some words vocabulary that gives impact on their understanding. 2Students have less motivation in reading. Most
of them did not try to ask their teacher when they found a diffcult word, consequently, they need a long time to read or give up finishing their reading. 3
Students‘ attitude to text is ―text knows best‖. The students think that the all content of the text is correct. In that makes students tend to passively accept what
is found in reading. 4 Boring atmosphare. Students also have lack of interest at the starting points in a reading class especially when they found unfimiliar topic
of the text that may lead to the whole boring atmosphere. 5 Students maynot utilize their prior knowledge with the information stated in the text, whereas, it
will help them to comprehend the text they read.
By consedering the problems above, Know, Want and Learned KWL Chart may be a solution. Here the main reason why K-W-L Chart may solve the
students‘ reading problem. The process of K-W-L do in a group and activiting their prior knowledge. From the group students may discuss about the topic
include the difficult word. It is also providing an opportunity for students to expand ideas beyond the text by sharing one another by variety of backgound
knowledge. So, they motivate them to write more and more the information that their group have known about the topic. The class atmosphare will become active
and interesting because they know what are being discuss. In short, it will help students to comprehend the text as pre-reading, a long reading and past reading
activities.
