The Effectiveness of Using Mnemonic Devices in Teaching Vocabulary at The Seventh Grade of SMP N 2 Prembun in The Academic Year of 2015/2016

Abstract

The objective of this research is to describe whether using “Mnemonic Devices” is effective in teaching vocabulary at the seventh grade of SMP N 2 Prembun in the academic year of 2015/2016. The researcher took 60 students as the sample. Class VII D consists of 30 students as experimental group and class VII E consists of 30 students as control group. To collect the data, the researcher used test as instrument. It was done by giving pre-test and post-test to both classes. Meanwhile, to analysis the data, the researcher used t-test. The result of t-value is 3.644. Based on the t-value on t-table for (n1=30 and n2=30) and the significance level is 5%, the value of t-table is 2.002. The computation shows that t-value was higher than t-table is (3.644 > 2.002). Another result is the mean of experimental group is higher than the mean of control group. The mean of experimental group is 76.70 ; meanwhile, the mean of control group is 66.30. The research findings indicate that using mnemonic devices is effective in teaching vocabulary at the seventh grade of SMP N 2 Prembun.
