The observation shows that the average students who still have mistakes in solving the mathematic problems as the students have not yet understood the concept of the lesson well. One way to solve the problem of students' concept understanding is to apply the REACE learning model (Relating, Exploring, Applying, Cooperating and Evaluating) oriented towards creating an independent learning environment, liveliness, cooperation elements and the ability to help teachers create concepts. This research is a quantitative research quasi experimental type research with nonequivalent control group design, specifically to see the effect of REACE on students' mathematical concept understanding. The analysis results show that the average of experimental class (77,36) with the gain test 0,48 (medium category) is higher than the control class (55,78) with the gain test 0,48 (weak category). The test t count> t table (4,192> 2,005) means that the applying of REACE affected the students' mathematical concept understanding. © Published under licence by IOP Publishing Ltd.
