Abstract:
This research aim to finds the effectiveness of KWL strategy in teaching
reading descriptive text. In order to know the effectiveness the researcher applied
quantitative method to discuss and find out the problem appearing in this study.
This study can be categorized as experimental research.
The population of this research is the seventh grade students of SMP
Muhammadiyah Purworejo and the researcher took 62 students as the sample which
divided into two class. The independent variable is the method of teaching, and the
dependent variable is the students’ reading result manifested in the test score. In
getting the data, the researcher used test as an instrument (pre test and post test).
The researcher analyzed the data by using descriptive statistic analysis (mean,
median, modus, SD, and the highest and lowest score) and inferential analysis
(normality test, test of homogeneity and t-test as hypothesis).
The result of the researcher showes that Know Want Learned (KWL)
strategy is effective in teaching students’ reading descriptive text. In teaching
reading descriptive text can also be seen by result of t-test that is 3.18. Then, the
researcher consulted the critical value on the t-table using 5% (0.05) alpha level
significance and the degree of freedom is 2.000. the computation shows that t-value
is higher than t-table is 3.18>2.000. Related to the result of t-test the mean of post
test experimental group and control group is higher than mean score of pre-test
(71.13>65.65). It means that Know Want Learned (KWL) strategy is effective in
teaching reading descriptive text at the seventh grade students of SMP
Muhammadiyah Purworejo in the academic year of 2015/2016.
