significantly improve their vocabulary compared to those students treated using the traditional
method or the intensive reading technique. This could be seen as follows: (1) the mean value the
students obtained in the pre-test was 75.93 and in the post-test was 89.93; (2) the T-test value of
44.61 was greater than the t-table value of 2.024 (44.61 > 2.024). Besides, the response of the
experimental group to the questionaires was positive about the extensive reading method.
