3.2.1 Population
The definitions of population are given in many books. Gay in Kumala 2007:28 states that
―the population is the group of interest to the researcher, the group to which heshe would like the results of the study to be in general
‖. ―Population is a group about which the researcher is interested in gaining information and drawing
conclusions ‖ Saleh, 2001:227.
Nunan 2003:25 states that ―population is all
cases, situations or individuals who share one or more characteristics ‖. Similarly,
Sugiyono 2010:55 states that ―population is a generalization area that consist of
object or subject which has quality and certain characteristic which was determined by researchers for being learned and drew conclusion from it
‖. Based on the statements above, it is very helpful for obtaining the data if the
writer chooses the population carefully according to the problem in the study. The eight grade students of SMPMTs learn four genres narrative, descriptive,
recount, and anecdote and the genre chosen in this research is descriptive text. Therefore, the population chosen in this research was the eight grade students of
SMP Takhassus Al- Qur‘an Wonosobo in the academic year of 20102011, which
has eight classes. Each of them consists of 25 until 30 students. Thus, the total number of population is 221 students.
3.2.2 Sample and Sampling Technique
After determining the population, the writer then selected a sample. Based on Best 1981:8 ―a sample is a small proportion of a population selected for observation
and analysis‖. A good sample is one that is representative of the population from which it is selected. Therefore, the representatives of a sample determine the
validity of the generalization of the result. The sample is made up of the students from the population who is chosen to participate in the study.
The writer used purposive samples in choosing the samples because of the administrative limitations in randomly selecting and assigning individuals to
experimental and control groups. Therefore, the writer used available classes as the samples. Those were VIII B as the experimental group and VIII H as the
control group. The experimental group was taught by using study tour method and the control group was taught only by using pictures of Kalianget Resort.
