Abstract

This research was conducted at Mathematics Education Study Program at Tarbiyah and Teacher Training Faculties of IAIN Padangsidimpuan at the third semester 2018-2019 academic year. Research method used is quantitative method with bivariate comparative analysis approach aiming to find out the significant differences in students' mathematical communication skills in statistical subjects. The design of this research is a one short case study  comparing the result of two treatments after the post tests. The research was conducted in one classroom, in which one treatment preceding the other treatment with different materials yet contain similar components and difficulties. The result of the research shows that there is significant difference in ability of mathematical communication between problem based learning and project based learning with tcount > ttable: 3,673 > 2,042; in which PjBL is higher than PBL.  In conclusion, PjBL is significantly better than PBL in term of students’ ability in mathematical communication

Abstract

This research was conducted in Grade VI at SD 200223 Sibulan-bulan Padangsidimpuan during the academic year 2023/2024, focusing on the topic of fractions. The aim of this study was to determine the effect of the Realistic Mathematics Approach on students' understanding of concepts in Grade VI at SD 200223 Sibulan-bulan. The study utilized a Post-Test-Only Control Group design and was of quasi-experimental nature. It involved an experimental group receiving the Realistic Mathematics Education Approach treatment and a control group not receiving such treatment. Both groups were selected randomly. The research findings indicate that students' understanding of mathematical concepts was better when using the Realistic Mathematics Approach compared to conventional learning methods. Based on the hypothesis testing results, it was found that t-count > t-table (2.23 > 1.98) and the Sig. value = 0.018, indicating that there is a positive effect of the Realistic Mathematics Education Approach (RME) on students' conceptual understanding. Based on the above findings, it is recommended that the learning process in schools use the Realistic Mathematics Education Approach, as it can improve students' conceptual understanding and mathematical abilities.
