VIII C as the control group. Test was used as the instrument to collect the data.
The tests which were used were pre-test and post-test. The test was in the form of
multiple choices. T-test formula was used to analyze the data. Based on the
computation, t-test result was 4.005 and t-table was 1.673 at the significant level
0.05 with the degree of freedom 54. It showed that t-test result was higher than ttable
(4.005>1.673). The t-test result for five components of reading
