Using purposive sampling technique, we obtained 24 students from class IVA SDN 09 Bandar Buat as the experimental class and 25 students from class IVB SDN 09 Bandar Buat as control class. The results showed that the average experimental class was 82,81 and control class 69.50. The results of the t-test calculation with a significance level of 0.05 obtained tcount > ttable is 4.493 > 2.012, then H0 is rejected and H1 is accepted. The N-Gain test in the experimental class obtained an average of 0.67 while in the control class obtained an average of 0.43.
