THE EFFECT OF SHORT STORY IN IMPROVING

THE EIGHT GRADE STUDENTS’ VOCABULARY MASTERY

AT SMP PGRI 1 KARANGPLOSO ABSTRACT

Vocabulary is an inseparable part of any language learning process. It would be impossible to learn a language without vocabulary because it supports all of the English skills such as listening, speaking, reading and writing. Considering the importance of vocabulary, the introduction of new vocabulary at the first stages of learning process to the students is necessary because it will lead them understanding a lot of vocabulary easily. However, learning vocabulary is not easy, based on the fact that the students’ achievement in English was not satisfactory. Short story is one of interesting materials used to improve the students’ vocabularies.

This study used quasi-experimental research design because in many situations in educational research, it was not possible to conduct a true experiment research design. In quasi-experimental design the researcher can control the treatment but cannot randomly assign subjects to the treatment because the individual are already organized in classes. The researcher divided the classroom into experimental group and control group. In this case, the experimental group was given a treatment using short story and the control group was thought without using short story. The population in this study was all of the eight grade students of SMP PGRI 1 Karangploso which were divided into five classes. The researcher used cluster sampling to select the sample. The researcher took the sample based on the class which has the lowest mean score of examination and daily task. As a result, class 8A was the experimental group and 8E was the control group. The instrument of this study was vocabulary test consisted of 20 questions.

Based on the result of pre-test, it was found that there was no significant difference on the students’ vocabularies achievement between the experimental and control group. The pre-test mean score of experimental group was 49.21 and the control group was 51.71. And the finding of the research showed that short story improved students’ vocabularies achievement of eight grade students. This was because the mean score of post-test of experimental group was 67.76 while the mean score of the control group was 62.23. Moreover, after being computed by using t-test it was found that te was 3.068 and the df of 74, then the tt value were found 1.99 at the level

significance of 0.05 and the tt value were found 2.64 at the level significance of 0.01.

The data showed that the value of te was greater than tt. Therefore, the alternative

CHAPTER I INTRODUCTION

This chapter discusses some topics related to the background of the study, the statement of problem, the hypothesis, the purpose of the study, the significance of the study, the scope and limitation, and the definition of the key terms. All of the items will be explained below:

1.1Background of Study

Vocabulary is an inseparable part of any language learning process. It would be impossible to learn a language without vocabulary because it supports all of the English skills such as listening, speaking, reading and writing. And it should not be neglected for anyone who learns english. Laufer(in Akbari, 2008: 2) states that

“Vocabulary learning is at the heart of language learning and language use. In fact, it is what makes the essence of a language. Without vocabulary, speakers can not convey meaning and communicate each other in a particular language”.

Considering the importance of vocabulary, the introduction of new vocabulary at the first stages of learning process to the students is necessary because it will lead them understanding a lot of vocabulary easily. However, learning vocabulary is not easy. Cameron (2001), says that learning a new word is not the simple thing. A new word should be given at least 5-6 times in one unit of text book in order to be learned by the students. So, learning vocabulary repeatedly is very important in order to thestudents always remember the material that they have learned. Because learning


(13)

vocabulary is not the simple thing to be done, the students get difficulties in this subject. It can be seen from the data of eight grade students at SMP PGRI 1 Karangploso that 60% of the students got low scores in english vocabulary. Therefore, it is very important for the teacher to find the solutions in order to make the students easier mastering vocabulary. One of the solutions is by giving an appropriate method, technique, material and media. It is expected that the students will be more interested in learning vocabulary.

The previous research done by Irawati (2005) under the title “The Role of

Simulation Method In Improving The Fifth Year Students’ Vocabulary Achievement

at SDN Torongrejo 02 Batu” showed a good result. The finding showed that

simulation method were effective to be used in teaching and learning vocabulary. The experimental group got better mean score than the control group. The mean score of the post test of the experimental group was 77,10 and for the control group was 63,95. After all the data were analyzed using t-test, it was proved that t-value was greater than the t-table (3,97>2,042) at the level significance of 0,05.

The previous research above is conducted to know the role of Simulation

Method in improving the students’ vocabulary achievement. However, in this study,

the researcher wants to apply short story in vocabulary lesson. The researcher wants to know the effect of short story in improving students’ vocabulary mastery.

According to Burroway (in Koesnosoebroto, 1988: 12 ), “Short story is short, and can

waste no words. It can deal with only or a very few consciousnesses”. Furthermore, Hooper (1992),says that story is different from a novel in that it is short enough to be read in one sitting, with every word leading toward some final, preordained effect. In

short story, the sentences are generally shorter in order the students easy to understand the story.

The researcher uses short story because it is one of an interesting materialshelps the students to find out the keys to remember and grasp many new vocabularies. Besides that, the students will be easy to write down the correct words. It is because all the words are inside of the short story. Murdoch (in Erkaya, 2002: 3), tells that if the short story that is choosed appropriate and supply good quality text it will increase the ELT program to the students. Here, the researcher uses recount and descriptive short story because these texts are being taught in first semester of eight grade students. It can be proved from the syllabus for eight grades in first semester.

The explanation above is the reason why the researcher is interested to

conduct the research entitled “The Effect of Short Story in Improving the Eight Grade

Students’ Vocabulary Mastery at SMP PGRI 1 Karangploso”. The researcher wants

to know whether or not short story improves the students’ vocabulary mastery.
