Abstract.There are manystudentswhohave difficultyin solvingmath problems. Their achivement score are very low. The aplication of Aptitude Treatment Interaction (ATI) learning model is important toimprove learning achivement and student activities in solvingthe Algebraill Rate Factorisation problems at eigthgradeSMP Negeri2 Glenmoreyear2013/2014. This research type is a Classroom Action Research (CAR). The data analysed in this research are student’s activity, and learning achivement. The research show that student’s activity attain 77,14% in the first cycle and 82,39% in second cycle, student’s learning achivementattain 85% in the first cycle and 90% in second cycle, and for the teacher’s activity attain 90,91% in the first and 96,97% in the second. It can be concluded that the aplication of Aptitude Treatment Interaction (ATI) learning model is effective to improve student’s learning outcomes in solving Algebraill Rate Factorisation.
