The research design uses: Randomized control groups pre-test and post-test design. Hypothesis testing uses statistical techniques with t test. The results of calculation analysis using t-test statistics obtained an observation t value of tob = 3.470. meanwhile, form the table of critical values t with a real level of α = 0.05; n1+n2-2 obtained a t table value of ttab = 2.101. This fact shows thet the value tob = 3.470> t tab = 2.101, thus the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted.
