KEEFEKTIFAN STRATEGI K-W-L-A (KNOW-WANT-LEARN-AFFECT) DALAM PEMBELAJARAN MEMBACA PEMAHAMAN TEKS EKSPOSISI SISWA KELAS VII SMP NEGERI 1 TEMPEL

Abstract

This research has two purposes. First is to find out the difference of
reading ability in exposition text comprehension, which is significant between
students obtaining learning process through K-W-L-A strategy and those who
gaining the learning process through conventional strategy. Second is to examine
the effectiveness of K-W-L-A strategy compared to conventional one in reading
learning process of exposition text comprehension of students grade 7th
  in SMP
Negeri 1 Tempel.  
This research is conducted using quantitative approach, apparent
experimental method, and pretest-posttest control group research design. There
are two variables in this research: unbounded variable, which is the K-W-L-A
strategy and bounded variable, which is the ability in reading exposition text
comprehension. Populations in this research are the students grade 7th
  of SMP
Negeri 1 Tempel. The determination of sample uses cluster random sampling
technique, in which Class 7th
 B has been chosen as the controller group and Class
7th
 C as the experiment group. The validities of the instrument usedare content
validity and construct validity. Content validity is done by expert judgement, and
construct validity uses Iteman program. Reliability examination in this research
uses Alpha Cronbach formula in Iteman program. The data are collected using a
test in the form of multiple choices. The  data analysis technique uses t-test in
SPSS version 22.0-computer program with significanceof standard 5%. Analysis
prerequisite test result shows that pretest and posttest score distribute normal and
homogeny.  
The research result shows that, firstly, there is a different ability of reading
comprehension in exposition text, which is significant between students who gain
learning using K-W-L-A strategy and those who gaining the learning process
through conventional strategy. The difference is shown with t-test result in which
t is 5,434, df 62, and p value is 0,000 (p<0,05=significant). Secondly, K-W-L-A
strategy  is effectively proved in reading learning process in exposition text
comprehension for students grade 7th
 in SMP Negeri 1 Tempel. This is shown by
experiment group t-test result in which t is 23,900, df 31, dan p is 0,000 (p<0,05).
In addition, the average gain score of controller group is 0,96, and experiment
group is 4,41 (KE>KK=effective).
