The low learning outcomes about mathematics are the background of research problems. The purpose of this study was to improve the mathematics learning outcomes of multiplication material through the Realistic Mathematics Education (RME) learning model for grade III students in the even semester of the 2019/2020 school year. This research method is Classroom Action Research which follows the model of Kemmis and Taggart.  This research includes 3 cycles where each cycle includes 4 stages, namely planning, implementing, observing and reflecting. The research time was from January to March 2020 with 30 students as research subjects, while the data were collected through tests, interviews and observations. The research results show that there is a significant increase in mathematics learning outcomes in class III. This is evidenced by the increase in the average result of the math test in each cycle, namely in cycle 1: 64.26 then cycle 2: 70.86 and cycle 3: 78.2. The results of researcher's observations in each cycle also increased, namely in cycle 1 = 2.44; cycle 2 = 2.88; cycle 3 = 3.89. Likewise, the results of student observations also increased, namely in cycle 1 = 2.4; cycle 2 = 3,2; cycle 3 = 4. And the results of the interviews conducted concluded that learning mathematics through the Realistic Mathematics Education (RME) learning model was fun for students. This study concluded that learning mathematics using the Realistic Mathematics Education (RME) learning model can improve student mathematics learning outcomes on multiplication material.

This study aims to prove the effect of the  PAIKEM GEMBROT  model on mathematics learning outcomes in fractions material, between students who are given learning with the  PAIKEM GEMBROT  model compared to students taught with the Jigsaw cooperative learning model. This research was conducted for two months to be precise, namely January to March 2019, with a total sample of 60 students, to be precise 30 VD class students who were given using the  PAIKEM GEMBROT  model and 30 students in VA class using the Jigsaw cooperative learning model. . Based on the calculation, it was found that the average learning outcomes of students through the  PAIKEM GEMBROT  model had an average of 73.5. Furthermore, the learning outcomes using the average model are 60.1. Based on the hypothesis test, the value of tcount = 5.101> t table = 2.00172 is obtained. So it can be concluded that H1 is accepted and Ho is rejected. The conclusion of this study is that there is a significant difference between the mathematics learning outcomes of students who are taught using the  PAIKEM GEMBROT  model and the Mathematics learning outcomes using the Jigsaw cooperative learning model on fraction material in class V Jatirangga 03 Bekasi elementary school.
