THE EFFECT OF USING FOUR SQUARE WRITING METHOD ON STUDENTS' WRITING SKILL
The research entitled "The Effect of Using Four Square Writing Method on Students' Writing Skill" has an aim at investigating whether four square writing method can affect students' writing skill in writing analytical exposition text. The research was conducted to the eleventh grade students of SMA PLUS PGRI Cibinong. In conducting the research, the researcher uses proportional random sampling by taking two classes majoring social studies; she takes 70 students as the sample. The researcher applies true experimental method and uses pre test post test control group as the design. The first group as experimental group taught by four square writing method and the second group as control group taught by mind mapping. She gave pre test to both experimental and control groups at the beginning, four times treatments and post test at the end of the term. The researcher gave analytical exposition writing test to measure students' writing skill. The data were analyzed using t test formula. From the calculation, she finds that the t test value is 5.60, the value of the degree of freedom (df) is 68, and the list of value in t 0.05 level of significant is 2.39 and in t 0.01 of significant is 1.67. Since t calculated is higher than t table (5.60 2.39 1.67) it means that the alternative hypothesis (Ha) is accepted. So, it can be concluded that the use of four square writing method affects students' writing skill of analytical exposition text in term of content, vocabulary, and language use.
