3.2. Subject of the Research
This section presents the subject of the research of the study. It is divided into four parts: the profile of the class, the population, the sample and the
sampling. a. Profile of the Class
The classes participated in this research were all in the sixth semester; those who are going to take the English proficiency test as one of the requirements
for their final paper proposal examination. The experimental group were taken from Information System Study Program whereas the control group were from
Informatics Study Program. Both of the study programs has the same curriculum for the english lessons thus the ability of the students in both Study Program more
or less are the same. b. Population
Fraenkel and Waellen 1990:68 stated that population is a group which is treated by the researcher as the object to generalize the result of the research.
Moreover they also stated that a population is the group to which the results of the study are intended to apply 2000:103.
The population of the research is the sixth semester students who will take a TOEFL ITP certification. The total of the population are the total of the
students who will take a TOEFL ITP test in July 2014 that is 378 students. Populasi sample :
c. Sample A sample is a part of population in which its characteristics are similar to
the population. It can be said that a sample should represent the population sufficiently since it is the population‟s representative Rasinger, 2008. The
sampling technique used in this research is purposive random sampling. Simple random sampling is the basic sampling technique where we select a group of
subjects a sample for study from a larger group a population. Each individual is chosen entirely by purposive, so it is called purposive random
sampling. This study focuses on the sixth semester students of STMIK Widya Pratama Pekalongan in class 6P4 and 6P5; in which class 6P4 as the control
group and class 6P5 as the experimental group. Based on the writer‟s
observation, they have more or less the same ability, as it is also proved by the results of the pre test that is is presented in appendixes. The number of the
control group is 66 students and the experimental group is also 66 students. Hence the total numbers of the sample are 132 students, it is about 30 percent of
the total population.
d. Sampling Sampling is the act of drawing a sample from a population Mason and
Bramble, 1997:113. In this research, the writer used random sampling. quasi experimental
