The lowest mean with the mean value 9.29 is found in chapter 6 pre-test implied that students have very weak basic in the concept of logarithm. On the other hand, pre-test of chapter 2 with the mean value of 64.29 and chapter 4 with the mean value of 63.02 indicated that students have better understanding in solving the equation in one variable and inequality beforehand. The chapter of logarithm is still reported having the lowest mean with the mean value of 61.96 in post- test yet the result shows that there is about 52% of improvement after the canip. The highest mean value is found in chapter 3 post-test with the mean value of 90.61 and an increase of 65% makes it become the highest percentage of increase among seven chapters. The figure revealed that the program had intensifying the students' capability in solving the quadratic equation. In pre-test, the standard deviations are quite dispersed compared to post-test. Generally, the overall disperses have greatly reduced in the post-test with the standard deviation values reduced to 24% or below. The standard deviation value increased in chapter 6, however, the mean values show the increment which means students had gained more understanding in the particular chapter
