This study deals with the effect of POW+TREE Strategy on students™ ability inwriting hortatory exposition text.. The problem of the study is to find out whether
POW+TREE Strategy significantly affects students™ ability in writing hortatory
exposition text or not. This study was conducted by using experimental design.
The population of the study was the students of eleventh grade of SMA Methodist
8 Medan in the academic year 2015/2016, there were 3 parallel classes of grade
XI. There were two classes selected to be sample. The Experimental group (XI
IPA-2) was taught by applying POW+TREE Strategy, while the Control group
(XI IPA-3) was taught by applying conventional strategy. The data of the study
was obtained from the students™ scores of writing test. There were two kinds of
test used in this study. They were pre-test and post-test. The data were analyzed
by applying t-test formula. After analyzing the data, the result of the study showed
that t-observed (2.338) was higher than t-table (1.994) (t-observed > t-table) at the
level of significance of p=0.05 and the degree of freedom (df) = 68. It can be
concluded that applying POW+TREE strategy significantly affects students™
ability in writing hortatory exposition text, or in other words, the null hypothesis
is rejected , therefore the alternative hypothesis is accepted.
