ABSTRACT
In the learning activities of the fourth-grade students at SDN Mangunharjo, they had difficulty understanding learning material, especially fractional material. According to the results of interviews with the fourth-grade teacher, students experienced problems understanding multiplication resulting in learning outcomes under KKM 65. This research aimed to analyze the effectiveness of implementing the PMRI approach to optimizing the results of learning fraction material for class IV students at SDN Mangunharjo. The research method used is a quantitative method with a pre-experimental research design in the form of a one-group-pretest-posttest. Implementation of the PMRI approach with an initial trial of class V at SDN Kemijen 02 with as many as 28 students and a final tryout for class IV at SDN Kemijen 02 as the control class and class IV at SDN Mangunharjo as an experimental class. Techniques and data collection include questionnaires, observations, test questions, and documentation tested for validity, reliability, homogeneity, level of difficulty, and discriminatory power. Based on observations from observers, it showed that the implementation of the PMRI approach in the learning process from the second meeting was 88.75, and the third meeting increased by 91.75 these results were in the very good category. While the results of the posttest class classical completeness test were 82.93 out of 29 students with a percentage of 83%, for the pretest class 42.72 with a percentage of 0% of 29 students, none of the students achieved the minimum completeness criterion score. This data shows that the class with the learning process using the PMRI approach is better than the conventional or lecture learning process. It means that applying the PMRI approach can optimize the learning outcomes of fourth-grade students at SDN Mangunharjo.
