CHAPTER III RESEARCH METHODOLOGY
This research specifically depicts the method and the design, the place and the time, population and sample, research instrument including validity of the
instrument, technique of data collection, technique of data analyzing including the test of normality and homogeneity and test of hypothesis, and statistical
hypothesis.
A. Place and Time of the Research
This study was conducted at SMA Daar El-Qolam Gintung Jayanti Tangerang which located at Jalan Raya Serang KM. 35 Desa Pasir Gintung,
Jayanti Tangerang, Banten 15610. The research was conducted from November 2014 to Maret 2015.
B. Method and Research Design
The research method used in this research was a quantitative method, namely quasi-experiment. The reason why the writer used experiment method was
because the writer only wanted to know whether an idea test or procedure as independent variable affects an outcome or dependent variables.

Particularly in this resea
rch, the writer wanted to know whether using blog affect students’ outcome namely, their accuracy and complexity in writing.
In quasi experimental research, the writer did not give a random assignment as in the true experimental research because randomly assigning will disrupt the
classroom learning.

There were at least two variables in this research, namely independent variable and dependent variables. Independent in this research was
referred to as experimental variable the treatment. The writer would have two groups as a control class which did not receive treatment and as an experiment
class which received treatment. The research would have pre-test and post-test to

measures whether blog was effective towards accuracy and complexity in writing.
The design of the study assigned the participants with pre- and posttest design followed the pattern at Table 3.1, as follows:

There was a different treatment between experimental and controlled class. In experimental class, students would have been treated by certain treatment, - by
using blog to students accuracy and complexity in writing – whereas in
controlled class students taught without using blog.
C. Population and Sample
The population of research was the students of SMA Islamic Boarding School Daar El-Qolam Tangerang. The sample was XI grade students. The
writer took two classes XI IPA A and XI IPA B as the object of the study. The XI IPA A class was as an experimental class, while the XI IPA B was as a
control class. Each class had 20 students, so the total numbers were 40 students. The writer gave treatment accuracy and complexity in writing with blog in class
XI IPA A as experiment class and write without blog in class XI IPA B as a control class.
