ABSTRACT Riny Purnama Fitri, 2314.131. The Effect of Keyword Mnemonic Technique Towards Students Vocabulary Mastery at the First Grade of MTS N 6 Agam. A Thesis, State Islamic Institute of Bukittinggi, 2019. This research was due to several problems found in the field that were: the students were still lack of vocabulary, most of students were difficult to remember vocabulary and forget easily and teacher still used conventional strategy in teaching vocabulary. In teaching vocabulary mastery, the researcher used keyword mnemonic technique to teach students vocabulary mastery. This research was an experimental research by using quantitative approach, the population of this research was at first grade of MTS N 6 Agam. The total sampling was 64 students from class Vll 3 and Vll 4. Class Vll 3 was used as experimental class in which the treatment was given, while class Vll 4 was used as control class. Purposive sampling technique was used as sampling technique in this research. To analyzing the data, the researcher used liliefors test to test the normality and f test to test homogeneity. Then, to test the hypothesis the researcher used t test which (α) = 0,05. Based on the calculation of pre test and post test from experimental class, it was found that the t obtained (9,33) was higher than the t table (1.960) with the (df = 62 and level of significance (α) = 0,05/2 = 0,025. So that, the alternative hypothesis (Ha) was accepted which means that there is significant effect of keyword mnemonic technique on students vocabulary mastery. Then, the calculation of post test both classes were the t-obtained (5,86) which was higher than the t-table (1.960) with the (df) = 62 and level of significance (α) = 0,05/2 = 0,025. So that, the alternative hypothesis (Ha) was accepted which means that there is significant difference between using keyword mnemonic technique and using conventional strategy. Then, the t-obtained in post test both classes were (5,86) which was higher than t-table (1.645) with (df = 62 and level of significance (α) = 0,05. So that, the alternative hypothesis (Ha) was accapted which means that the students who are taught by using keyword mnemonic technique is better than the students who are taught by using conventional strategy. So it can be conclude that the entire hypothesis were accapted. Therefore, it was proved that using keyword mnemonic technique give effect towards students vocabulary mastery at first grade of MTS N 6 Agam.
