How to improve students mathematics problem solving by implementing indonesian realistics mathematics education (IRME) approach

This research aims to know How to improve Students Mathematics Problem Solving by implementing IRME. It is a quantitative research with experiments method and Randomized Control Group Posttest Design. Research samples are obtained randomly from XIth Grade in State Senior High School in Center Jakarta. This research has an independent variable and a dependent variables. The independent variable is a learning approach and the dependent variable is Students Mathematics Problem Solving ability. This study took 60 samples, which were 30 students from SMAN 7 Jakarta dan 30 students from SMAN 25 Jakarta, as samples. Both schools are taken because they are considered to represent the school population, especially in Indonesia. They also have many similarities, like they are located in the center of Jakarta, using Curriculum 2013 and being accredited A. Data was collected by test technique. Data has processed by using t-test in one way in significant level 0,05. The result is There is a significant direct influence of learning approaches toward Students Mathematics Problem Solving ability.
