Method and Design of the Research

the dependent variable is blog and writing skill is as an independent variable. The experiment procedure starts with a pre-test and ends with a post-test. Researcher need to analyze the findings based primarily on differences in the post-test scores of the sample group. Singh states, “The single individual or one-group experiment is the most elementary and least rigorous design.” 3 So, the researcher believed this design will meet to the objective of the research. In addition, “It consist of comparing the growth of a single group under two different sets of condition-that is, of subjecting of the group successively to an experimental and to a control factor for equivalent periods of time and comparing the outcomes” 4 In the first meeting, the researcher invited the participants to language laboratory and asked them to create an account in Blogger platform. The researcher chose that blog provided because it is easy to be used and the features support for writing. The next meeting was pretest to see their current writing skill level. The researcher asked students to write Narrative text including fable, legend, myth, fairy tales, folklore and many more. The students were asked to write at least 3 paragraphs. They are divided into 10 groups to make easier in commenting others writing. The four students who have first registered number commented to each other writing among the fourth and the following registered number will do the same. Based on the kinds of participant comment, the students were divided into two groups in analyzing peer feedback which are the elaborated and basic feedback group. Elaborated feedback refers to useful feedback which provides detail items from students and basic feedback is merely led to good or poor comments. The following weeks, the researcher started the treatment for 2x45 minutes. Then, they have been given treatment during that time. In the next week, the student did post-test using computer in the language library. The researcher picked categorized participants based on their kinds of comment to be interviewed. Then the researcher correlated between the results of participants’ writing and interview. 3 Yogesh Kumar Singh, Fundamental of Research Methodology and Statistics, New Delhi: 2006, New Age International P Ltd., Publisher, p. 141. 4 Ibid.

C. Population and Sample of the Research

The population in this research was students of SMA Negeri 3 Kota Tangerang Selatan. There were 293 students tenth year in eight classes; X MIA, X MIA 2, X MIA 3, X MIA 4, X MIA 5, X MIA 6, X IIS 1 and X IIS 2. The samples class is X MIA 5 which is consisted of 13 male and 24 female. The technique of sampling used in this research was a convenience sampling. “A convenience sample is motivated by analytical interest in an available body of texts that is known not to include all texts of the population that the analysts are concerned with.” 5 The availability to select participants as a sample because of students’ availability to be studied at school is the reason beyond the researcher chose this sampling. The principle of the school gave permission and instructed the teacher to give English class accessibility to do research.

D. Instrument of the Research

To measure data in quantitative study, the researcher used instrument. In quantitative data, a tool for measuring, observing documenting is called instrument. 6 Instrument also can be defined as device to collect data and the process of collecting data is called instrumentation. In addition, Brown emphasized that a set of techniques, procedures, or items that requires performance on the part of the test taker refers to an instrument. 7 The instrument used in this research was a written test. The researcher gave instruction to write Narrative text by written test. In addition, the instruction can be seen on appendix. It is done because to see the writing ability is better to get the students write. The written test conducted in the research including pretest and posttest. The researcher gave instruction to make blog account using Blogger platform. Whether students already owned blog or not, they should create a blog account. 5 Klauss Krippendorff, Content Analysis: An Introduction to its Methodology, California: 2004, Sage Publications, Inc., p. 120. 6 Creswell, op. cit., p. 14. 7 H. Duglas Brown, Language Assessment Principles and Classroom Practices, New York: 2004, Pearson Education, Inc., p. 3. Since the problem of the research is to see the students’ writing ability in Narrative text, so the instrument used is analytic scoring rubric. Moreover, peer feedback provided by the participants is also counted and divided into elaborated feedback and basic feedback both individual and in group. There was only a single group in this study and it was doing pretest and posttest. The researcher gave pretest to gather data before treatment applied. Posttest is given after treatment is applied to see the effectiveness of the treatment which given.
