3.3 Research Participants
The participants of this research were the eleventh grade students of SMAN 11 Yogyakarta, particularly the social science students, who learnt writing report
texts in the academic year 20122013. The eleventh grade students were chosen because of some considerations. First, the students had learnt writing report texts,
which was the genre of writing produced by the students in this research. Second, the students had experienced the implementation of peer feedback in their writing
classes, which was the main focus on this research. Last, the researcher could not choose the twelfth grade students as the participants because they had to focus
their study on the National Exam. Therefore, the researcher chose the eleventh grade of SMAN 11 Yogyakarta, particularly the social science students, to be the
research participants in this research. As the students were able to provide meaningful data in this research, the
researcher employed purposive sampling. According to Fraenkel 1994, purposive sampling is a sample selection in which the researchers use judgement
that they believe will provide the data needed. In this research, the researcher believed that the students were able to provide the data on students’ perception on
the implementation of peer feedback in writing report texts. They had experience writing report texts and provided peer feedback in writing their report texts.
There were three social science classes in SMAN 11 Yogyakarta. The total number of students in three social science classes was seventy-six. The researcher
distributed the questionnaire to all social science students. There were seventy-six questionnaires distributed but only seventy participants filled in and returned the
31 questionnaires. Hence, the participants of this research were seventy social
science students of SMAN 11 Yogyakarta.
