There were two classes in the eight grade and the researcher took both classes for sample. There were 26 students for experimental class and there were 22 students for control class. Instrument for collecting the data in this research was test in the multiple choice form. Before conducting the treatment, the researcher gave pre-test and giving post-test in the last meeting. In treatment, students in experimental class were taught by using mnemonic strategy and students in control class were taught without mnemonic strategy (conventional strategy). The experimental class got improvement as much as 24,81 points (pretest=41,15 while post-test=65,96). Mnemonic strategy has a significant effect on the students? vocabulary mastery. The result shows that the tvalue is 3,147 while the ttable was 2.01 (tobserved> ttable, 3,248> 2.01). Therefore, Ha is accepted and H0 is rejected. So, it can be concluded that there is a significant effect of mnemonic strategy on the students? vocabulary mastery at eight grade of MTs Nurul Hakim.} }
