CHAPTER II THEORITICAL FRAMEWORK
C. Previous Study
The writer found some preliminary studies conducted by other researchers related to the same topic. Other studies are considered as useful information that guides the writer in completing this thesis. Those studies are:
The first is a study that was conducted by Selfa Idriani entitled “The Effectiveness of Vocabulary Self-Collection Strategy and Motivation on Students’
English Vocabulary Mastery.”22 This study is aimed to prove whether Vocabulary Self-Collection Strategy and students’ motivation give a significant effect on the students’ vocabulary mastery on English Subject. Then, the instrument used to collect the data is vocabulary test.

From this study, the researcher found that the experimental group gained higher score than the control group which means that the vocabulary self-collection strategy gave a significant effect on students’ vocabulary mastery.
The second research relevant to this topic is a study conducted by Husniah and Syahfriati entitled “The Vocabulary Mastery of the Seventh Grade students through vocabulary Self-Collection Strategy.”23 This research focuses on extending the effectiveness of the strategy on students’ vocabulary of students’ at the seventh grade.

higher than control group. The result had shown that the Vocabulary Self-Collection strategy was effective to improve students’ vocabulary mastery.
Moreover, the researcher added that the vocabulary self-collection strategy was highly recommended for low-level students at mastering vocabulary.
The last previous study found by the writer is “Using the Vocabulary Self-Collection Strategy Plus to Develop University EFL Students’ Vocabulary Learning” conducted by Manal Mohammed Khodary.24 The main goal of this study is to examine the effectiveness of using the vocabulary self-collection strategy plus on developing university EFL students’ vocabulary learning. This study is a kind of quasi-experimental study that was intended for first-level students at Languages and Translation Department, Arar Faculty of Education and Arts, Norther Border University, KSA. The researcher used VAT as the instrument of the study. Having analyzed students’ performance in both experimental and control group, The result showed that the experimental group was outperformed the control group. It can be concluded that Vocabulary Self-Collection Strategy Plus had a great role in developing students’ vocabulary.
From the previous studies above, it can be found that the difference between this study with the previous study is on the sample. This study took the sample from students at Senior High School grade, meanwhile, the two previous studies above took the sample from Junior high school students and another is from college students. Then, this study focused on using procedure text as the text given to the students which is different from those previous studies.
D. Thinking Framework
Vocabulary is related to the knowledge of meaning words. It has an important role in students’ understanding of such materials relevant to learn foreign language.

vocabulary into those planned activities. Therefore, mastering vocabulary must be emphasized in learning foreign language.
In fact, teaching vocabulary is not as easy as we think. Practically, The focus of that is how the students can gain many vocabularies through teachers’
instruction without being unmotivated. To gain that purpose, teacher should apply the appropriate strategy in teaching vocabulary. In addition, a lot of strategies were discovered by experts to solve the problems of teaching vocabulary. One of them is Vocabulary Self-Collection Strategy.

Even more the students fully engaged in the process of learning so they will not be bored in finding it. This strategy will also enable students to reach vocabulary mastery through their broad knowledge of words connecting to the context. From the context delivered, students are involved in the process of select, define, finalize, and extend the selected words which nominated by their each group.
Therefore, the writer would like to perform a research on the effectiveness of Vocabulary Self-collection strategy on students’ vocabulary mastery. The writer would like to find out if this strategy can become a solution for the students’ vocabulary mastery problems.
