INTRODUCTION
Now days, an international language, English become important language. English help people communicate and interact with other people from different countries, and also to develop science, technology, art and culture. Knowing and mastering English language is given the benefits for students. Indonesian student study English as a foreign language in the elementary until university and also there are from kindergarten level. English have four skills : speaking, reading, listening, and writing, and Vocabulary is an important component to learn language .
The students must able to master those skills, besides that the students also need to have a wide vocabulary, because vocabulary is a central to English language learning. Sufficient in vocabulary can help the students to express their own ideas and help to understand others. Thornbury (2002) states that While without grammar very little can be conveyed, without vocabulary nothing can be conveyed. This point reflects than even without grammar, with some useful words and expressions we can manage to communicate. Students often instinctively recognize the importance of vocabulary to their language learning. Vocabulary is words consist of meaning in order to express ideas and feeling so that the speaker and the listener can understand each other better.
Vocabulary is something crucial and indispensable for the students because the success of their study depends on the greater part of their vocabulary. Having a good vocabulary will help students to master language skills. It is almost impossible to learn on words. From the statement above it can be concluded that vocabulary is the first element in English that we should be mastered.
Even though we obviously know vocabulary is an important language component that should be mastered by students, but there are still many students who still lack of vocabulary. The lack of vocabulary causes students cannot are understand English well. It often occur, in teaching and learning activities there are still many students who can not answer teacher question and keep asking the teacher to translate the question into first language (Indonesia). When reading some text book the students do not know the meaning of the text that written in English, the same as their writing ability, when the teacher ask them to make a paragraph. The students really depend on the dictionary to make English word.
There are several reasons why students still lacking on vocabulary which are students feel bored because the technique by the teacher is monotonous, students are not interested in learning English and consider English as a difficult subject and lastly is the lack of use the media because the teacher only always relay on the speech method without involving media. It is necessary for English teacher to make materials more interesting and motivating so that the students can progress their vocabulary knowledge.
Many factors that affecting the students are difficulty in mastering the vocabulary. First, the students are difficult to understand and remember vocabulary. Many students were obtaining difficult when they speak because restrictiveness their vocabulary. Second, learning English was serious that made students depressed or afraid to develop their ability in vocabulary. Third, the students difficult to understand and try to memorize the vocabulary. They were easy to forget vocabulary has been taught or learn. Fourth, the students lazy to consult the dictionary and do not use vocabulary on daily communication. Fifth, students do not comprehend words meaning and the usage of the word in context.
To solve the problems above and to find the solution, then the researcher chose the thesis with the title " The Effect Of BINGO Media To Improve Students Vocabulary Of The Seventh Grade Students At SMP S Al -Washliyah 27 Medan " . Because One of the ways that the teacher can use to make students fun, interactive, and empowering in learning vocabulary is by using the various vocabulary games (Farrel, 2009). From the opinion that related to the game, it is reckoned that a game is one of the effective ways in teaching vocabulary. We can say that by using a game in teaching vocabulary can help the students to improve their vocabulary skill.
Bingo is a game for the whole class that encourages students to study and review their vocabulary words. Bingo game is one of the games that can bring fun in the classroom. This game is easy to be played because it helps students memorize the words and the game need simple supplementary media as pencil and the concerning cards as the media of teaching. The teacher will let students make some efforts in order to solve the problem given. When students are actively involved in problem solving process, students will memorize the new words deeply and be able to recall them easily instead of when the teacher just tells the students some new words Not only can Bingo game build word recognition students' skill, it is also able to develop students' grammar understanding, spelling skills, listening skills, and teamwork.

RESEARCH METHOD
In this research the research will focus on Quantitative research. Cresswell (2003) stated, quantitative research "employ strategies of inquiry such as experimental and surveys, and collect data on predetermine instruments that yield statiscal data". The design of research is categorized into experimental research. It means that two kind of treatment applied. There are two groups of students namely experimental group and control group. The experimental group is the group that receives treatment by using BINGO Media. While, the control group is the group which receives treatment without BINGO Media. The design is as follow table :

RESEARCH RESULT AND DISCUSSION The Data and Data Analysis
The test was taken from the vocabulary test students. The students in this case the researcher obtained the students score after applying the post-test to the experimental and control group. The result of the pre-test and post-test of the two groups can be seen in the following table: After collecting the data and scoring the experimental group's answer of pre test and post test that the researcher was given to the experimental group. It can show that the total scores of the experimental group test is for pre test, the experimental group got 1780 and for the post test they got 2510. The total scores of the control group test is for pre test the control group got 1655 and for post test they got 2070. Based on the table showed that, the deviation between pre-test and posttest in experimental group is 24,33 Based on the calculating of the t-test above, it was found that t-test is 6,94. The writer used the 5% (0.05) alpha level of significant as usually educational research. Determining degree of freedom (df), with formula: Df = (Nx + Ny) -2 = (30 + 30) -2 = 58 So, in the table (tt) is 2.002 for 5%.

Testing Hypothesis
To test the hypothesis, the formula of t-test and the distribution table of tcritical value were applied. If observed is higher than t-table, it's mean that the null hypothesis is rejected and the alternative hypothesis is accepted. The fact of this research showed that t-observed is higher that t-table (6,94 > 2.002). Therefore, Ha is accepted and Ho is rejected, in other words, teaching vocabulary using Bingo Media has more effective than without Bingo Media.

The students who were taught by using Bingo Media got higher score than the students who were taught without Bingo Media. 2. The t-observed value was higher than t-table in which t-observed was 6,94 and t-table 2,00 (6,94 > 2,00). Based on the finding of research, it was found that students vocabulary achievement in experimental class taught by Bingo Media was higher then students in control class taught by discussion method. From the data i got it the lowest for pre-test in experimental group was 50 and the highest was 75.
The lowest score of post test was 70 and the highest was 90. The lowest score for pre test of the control group was 50 and the highest was 65. The lowest score of the post test was 60 and the highest was 90.
For hypothesis by using t-test, it was found that t-observed 6,94 and ttable 2,00. It means that Ha was accepted and Ho was rejected. In the other word, the vocabulary learning by using Bingo media in experimental class significantly affected on students vocabulary achievement in grade VIII -A.
