ABSTRACTSusanti, Arum, Registered Number Students 172013163028, 2020. Using SemanticMapping to Improve Vocabulary Mastery of the Seventh Grade Studentsat MTs Darul Falah Bendiljati Kulon. Thesis. State Islamic Institute(IAIN) of Tulungagung. Advisor: Dr. Arina Shofiya, M.Pd.Keywords: Semantic Mapping, Improving Vocabulary MasteryVocabulary is one of the most important elements in learninglanguage. Vocabulary is important to be learned by the students who wantto master a language, especially foreign language. However, some studentshad low motivation on improving their vocabularies. It makes the studentshad poor vocabulary and passive in English learning process. Due to thisproblem, the researcher intends to help the students to improve theirvocabulary by using Semantic Mapping Strategy.The formulation of this research question is How can the use ofSemantic Mapping improve students’ vocabulary mastery of the seventhgrade at MTs Darul Falah Bendiljati Kulon. Hence, the purpose of thisresearch is to describe how Semantic Mapping Strategy could improve thevocabulary mastery of seventh grade students at MTs Darul FalahBendiljati Kulon.This research was categorized as Classroom Action Research(CAR). This study applied collaborative classroom action researchbetween the researcher and English teacher. The action was implementedin one cycle that covered planning, implementing, observing, andreflecting. In one cycle of this study consisted of three meetings. Theresearch subjects were the seventh grade class A at MTs Darul FalahBendiljati Kulon, which consists of 31 female students.The criteria of success in this research was the students’vocabulary mastery were improve and most of the students wereenthusiastic to participate the teaching and learning process. The findingsof this study showed that the use of Semantic Mapping Strategy in Englishteaching-learning was able to improve the students’ vocabularies. It wasprovided by students’ improvement score in the result of test in cycle 1.Where the students’ mean score of vocabulary test in the pre-cycle test was83 increased 90 for the cycle 1 test. It means that the mean score in thecycle 1 test increased by 7.0 from the mean score in the pre-cycle test.The students enthusiastic in participating the teaching andlearning process also increases. Based on the students’ participantchecklist from the analysis of teaching and learning process in vocabularymastery by using Semantic Mapping Strategy in cycle 1, it was found thatthe most of the students got improvement motivation. The motivationattract the students were active in teaching and learning process. It wasproven by the result students’ participant checklist was increases from thefirst meeting to the third meeting, that was mean percentage of the resultwas 85%.
