THE EFFECT OF PREDICTION AND INFERENCE STRATEGY ON STUDENTS’ READING COMPREHENSION IN ANALYTICAL EXPOSITION TEXT

This study aims at investigating the effect of prediction and inference strategy on
students’ reading comprehension in analytical exposition text. This study was
conducted by using experimental research design. The population of the study was
the students of grade XI of SMA Negeri 14 Medan in the academic year
2015/2016; two classes were selected as the sample by applying random
sampling. The sample was divided into two groups. The Experimental group (XI
IPA 1) was taught by applying prediction and inference strategy, while the control
group (XI IPA 3) was taught by using direct instructional teaching. The data of the
study were obtained by using objectives test. To determine the reliability of the
test, the writer used KR 20 formula. The data calculation showed that the
coefficient of reliability of the test was 0.81. It showed that the test was reliable.
The data were analyzed by applying t-test formula and the result of the study
showed that t-observed (4.29) was higher than t-table (2.00) (t-observed > t-table)
at the level of significance of α = 0.05 and at the degree of freedom (df) = 58. It
means that prediction and inference strategy significantly affects students’ reading
comprehension in analytical exposition text or in other word the alternative
hypothesis is accepted.
