To learn English, students need vocabulary in their effort to use English. Because without knowing more vocabulary, the students cannot study English well. It means that, vocabulary is very important for every learners who wants to master English because the learners will be difficult to master in English if they did not study vocabulary or their vocabulary is less. Students will experience difficulties in learning English if they lack vocabulary mastery. In fact, the students of Senior High School still lack of vocabulary and experience to memorize the vocabulary because the teachers use conventional method in teaching vocabulary. Nowadays, some innovations in English learning emerge for teaching vocabulary. One of them is hidden word game. The type of this research is experimental research. The number of the sample is 47. As the experimental group, the researcher uses class XI NKPI which consists of 23 students. Meanwhile as control group, the researcher takes 24 students of class XI TKR. The sampling technique which is used is simple random sampling. The instrument used to collect the data is a test. The form of the test is divided into two parts. Those are pre-test and post-test To analysis the data, the researcher used t-test formula. The result of the research shows that the mean score of pre-test in experimental group is 59.1 and the mean score of post-test is 82.5. While the mean score of pre-test in control group is 59.6 and the mean score of post-test is 64.9. Then the value of t-test is 8.41 and the t-table is 2.000. Then the researcher consults the critical value on the t-table using 5% (0.05) alpha level significance and the degree of freedom is 2.000.The result of computation shows that t-value is higher than t-table, that is 5.03>2.000 so it can be stated that the hypothesis “Hidden word game as a media for teachingvocabulary is effective” is accepted

Abstract

The objective of this research is to describe whether pictionary game is effective or not in teaching vocabulary at the seventh grade students of MTs Ma’arif As Sahro Rejosari in the academic year of 2015/2016. The researcher used Pictionary game in teaching vocabulary at the seventh grade students of MTs Ma’arif As Sahro Rejosari in the academic year of 2015/2016. This is a pre experimental research, the researcher took 24 students of one class as her sample from 68 students as population. Then, the researcher used pre-test and post-test to gather the data. After the data collected, the researcher analyzed the data. The researcher used t-test formula in order to answer the hypothesis stated. After doing the research, the researcher got the data from the pre test and post test. From the data in pre test, the mean of pre test is 68.33, the highest score is 80, and the lowest score is 50. In the data of post test, the mean of post test is 73.96, the highest score is 85, and the lowest score is 55. Based on the data of pre-test and post-test, the researcher can see that the mean score of post test (73.96) is higher than the mean of pre test (68.33). Seeing from the comparison between mean score of pre test and post test, it can be known that the students’ vocabulary achievement is getting better after the researcher used pictionary game as a technique to teach vocabulary. From the computation, it is known that the t-test result is 2.908 . Then, it is compared with t-table (2.073). From computation, it is known that t-value > t-table (2.908 > 2.073). So, Ha is accepted which mean that using Pictionary game in teaching vocabulary at the seventh grade students of MTs Ma’arif As Sahro Rejosari in the academic year of 2015/2016 is effective
