Abstract

This backgound of the researchis because the low of student’s intellectual mathematics
ability. The purpose is for knowing the difference result from increasing student’s

Nonequivalent Control Grouph Design. In this research, the population is taken from the

Shapiro – Wilk result test pretest, pos-test and N_Gain in this result are normality
distribution, and the result of Homogenity Levene’s test, pretest mark, post-test and N_Gain
homogen variety. After data is known normal varienty and homogen, so the next test is the
difference of post test on the average and it uses Inddependent sample t – test. The result of
this Independent samples t – test has point of (1 – tailed) 0,001<0,05 it means H0 refused.
And next the diffence on average test N_Gain and Independent sample t – test is got point
sig (1 – tailed) 0,0015 < 0,05, it is H0 refused. Mean while, based on the result of student’s
