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.
