experimental group, the researcher used class 7E which consists of 32 students.
Meanwhile, as the control group, the researcher took 32 students of class 7F. Then the
researcher gave pre-test and post-test to both classes. The researcher taught descriptive

control group is 62.72 and it is sufficient category. It can be concluded that the score
from experimental group is higher than control group. In addition, the result of ttestshowed
that t-value (sig.2-tailed) is 0.00 at the 95% confidence interval of the
differences. It is significance because the sig. (2-tailed) is lower than 0.05 (0.00<0.05)
Based on the result of t-test findings, it can be stated that the hypothesis “the use of
outdoor classroom activity in teaching writing descriptive text at seventh grade of SMPN
