INTRODUCTION

English is one of international languages, it means that English is learnt by many countries in the world, many people have used English for international communication and it is used as a key of knowledge, science and technology. So, English is very important to conduct communication everywhere, every time, and everything.
English language consists of four skills: listening, speaking, reading and writing. Vocabulary is one component of those skills. One cannot express his idea if the lacks of vocabulary. Vocabulary is important for the students to support their four language skills (David, 1991:9). It means that if the students master vocabulary, it will make the students easier to learn English language. Vocabulary is a unique to a content area as unique as fingerprints to a human being. Teachers know they must do something with the language of their content areas, but they often have trouble with what they should do. Consequently, they reduce instruction to routines that have withstood time and teacher centered practice, directing students to look up, define, memorize and use content specific words in sentences. Content area vocabulary must be taught well enough to remove potential barriers to students understanding of texts as well as to promote a long-term acquisition of the language of a content area. The organizing principle underscores the main premise of the chapter: teaching words well means giving students multiple opportunities to learn how words are conceptually related to one another in the material they are studying (Richard, 1999:314). In other words, vocabulary must be taught to the students in certain period to make them understand the text.
Vocabulary is taught in elementary level; in fact the students master simple vocabularies like animal, clothes, things in the classroom etc. They only have little vocabulary, it is caused by they do not have spirit to learn new vocabularies and the teacher rarely uses a suitable media to teach vocabulary. It will generate the students to have spirit to read the book. Then they will master English vocabularies.
Many people are difficult to master vocabulary because of the using of different techniques between English and Indonesia. The English people everyday use English language to speak others but in Indonesia most of the learners speak English language in certain condition. So, Indonesian students’ vocabulary is still poor. If everyone has motto “Book is the world’s window” because they like to read in order to enlarge and improve their knowledge.
The students got many vocabularies by conducting reading activity. That motivation gives task and practice by involving reading activity in order that the student can understand word by word and meaning of words. So that, they can learn vocabulary. Most of students begin to read something because they have seen and they have heard something that is pronounced by other people. Using of media is needed to conduct teaching and learning process in the class. The suitable media is audio visual media because the media contains picture and voice so the students can see and hear directly such as cartoon film. By using this media, the students will be enjoyable and pleasure to learn English vocabulary, make the message clearly, can save the teacher energy, can motivate the student to learn, can increase the quantity of teaching and learning.
Vocabulary is very important in learning English because by having many vocabularies someone can be easier to learn English. It is different when someone has limited vocabulary, they could not learn English better. For example if they have many vocabularies they will be easier to look for the information from English magazine or English newspaper and vice versa. It is better for students to use media in learning vocabulary, in order to make them easier in learning English. Media is medium to send message from speaker to receiver. It means that the media can help the teacher to send their information for their students. The examples of media are television, LCD projector, radio etc.
From the statement above this study focuses on choosing a suitable media that is audio visual media to teach vocabulary, in this case cartoon film is considered as suitable media. By using cartoon film the students seem easier to understand the vocabulary because they like the cartoon especially Dora’s cartoon. So, the students feel easy to follow the story and understand word by word in Dora’s film. Children like cartoon, so that they will enjoy teaching and learning in the classroom if a teacher uses cartoon. For the children, cartoon is fun. Putranti & Mina (2015) state that cartoon film offers a fun and meaningful teaching and learning experience.
A meaningful teaching comes from the ability of the teacher to choose the best and appropriate teaching method to be used in the classroom. A teacher should inspires the students in his/her class by implementing the interesting teaching strategies in his/her class. Iftanti (2015:1) states that an inspiring English lecturer is the one who could implement the teaching technique strategies and skills which is changing students’ learning style.
