The strategy of sampling was Non-probability Sampling; it means that this kind of sampling does not equally give the
opportunity for every population to be selected as the sample.
4
The technique of the sample was total sampling; where all population became the main sample.
The sample of this research was; the A class with 20 students as the experimental class and B class with 20 students as controlled class.
D. Instrument of The Study
The instrument that used for collecting the data was test, exactly a written test. It was divided into two tests, pre-test and post-test. A pre-test was given to
the students before the treatments and post-test was given after treatment. The test was a subjective test which asked the students to write in form of paragraph.
The topic of the writing task was about “ Study at Pesantren”. In pretest the
writer asked students to write at least 150 words into paragraph their arguments and opinions about their best moment when they study at Pesantren, write with
complex, compound and compound complex sentences. The prompt was “Describe your best moment when studying at Pesantren. Write in at least 150
words and make sure you use in complex, compound and compound complex sentences in your writing.” The writer expected students will write text with
complexity and accuracy. While in posttest the writer asked students to write at least 150 words into
paragraph. The topic of the posttest is about sex education for teenager. The prompt was “Describe your opinion about sex education for teenager. Write in at
least 150 words and make sure you use in complex, compound and compound complex sentences in your writing.” Finally the writer will see the students’
grammatical errors and number of subordination in writing.
