THE COMPARISON OF STUDENTS’ MATHEMATICAL PROBLEM SOLVING ABILITY ON CONTEXTUAL TEACHING LEARNING AND REALISTIC MATHEMATICS EDUCATION IMPLEMENTATION ON GRADE XI IN SMAN 1 LUBUKPAKAM ACADEMIC YEAR 2016/2017

The aim of this research is to know whether student’s Mathematics Problem Solving Ability taught using Contextual Teaching learning is higher than Realistic Mathematics Education for Grade XI in SMA Negeri 1 Lubukpakam at Academic Year 2016/2017. Sampling techniques that is used in this research is purposive sampling. There are two samples in this research those are, Class A is XI MIA 3 taught by CTL and Class B is XI MIA 5 taught by RME. Each of class consist of 30 students. Technique of analyzing data is consisted of normality, homogeneity, and hypothesis test. Based on normality and homogeneity test, the data was taken from normal distribution and homogeneous population. Hypothesis test is done by using analysis of t-test. The result of t-test show that tcalculated = 2.878 and t(0.5)(58) = 1.672. Consequently tcalculated > ttable, then H0 is rejected. So, we can conclude that students’ mathematics problem solving ability taught using Contextual Teaching Learning model is higher than taught using Realistic Mathematics Education
