AbstrakPemahaman konsep matematika masih rendah di kalangan pelajar baik pada tingkat dasar maupun menengah. Penggunaan pendekatan pembelajaran harus menjadi perhatian utama untuk memperoleh pemahaman konsep yang baik. Pendekatan Matematika Realistik (PMR) dapat dijadikan sebagai solusi dalam pembelajaran matematika. Penelitian ini untuk mengetahui apakah pemahaman konsep matematika siswa yang diajarkan dengan menggunakan PMR lebih baik dibandingkan dengan pemahaman konsep matematika yang diajarkan dengan menggunakan pendekatan konvensional. Penelitian ini merupakan penelitian eksperimen semu dengan desain penelitian Posttest-Only Group Control Design. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMP Widya Bhakti Ruteng yang berjumlah 95 orang. Pengambilan sampel kelas dilakukan menggunakan teknik random sampling yang diawali dengan pengujian kesetaraan kelas. Data dikumpulkan dengan menggunakan instrumen yang berbentuk uraian dan menggunakan teknik tes. Hasil penelitian menunjukkan bahwa pemahaman konsep matematika siswa yang diajarkan dengan menggunakan pendekatan matematika realistik lebih baik dari siswa yang menggunakan pendekatan konvensional. Penggunaan pendekatan matematika realistik pada pembelajaran matematika berpengaruh terhadap pemahaman konsep siswa. Effect of Realistic Mathematical Approaches on Understanding Students' Mathematical ConceptsAbstractUnderstanding the concept of mathematics is still low among students both at the elementary and secondary levels. The use of a learning approach must be a major concern to obtain a good understanding of concepts. Realistic Mathematics Approach (PMR) can be used as a solution to teaching mathematics. This study is to find out whether understanding the mathematical concepts of students taught by using PMR is better than understanding mathematical concepts taught using the conventional approach. This research is a quasi-experimental study with research design Posttest-Only group Control Design. The population in this study were all eighth-grade students of Widya Bhakti Ruteng Middle School, totaling 95 people. Class sampling is done using a random sampling technique that begins with class equality testing. Data was collected using instruments in the form of descriptions and using test techniques. The results of the study indicate that understanding students' mathematical concepts taught using realistic mathematical approaches is better than students who use conventional approaches. The use of realistic mathematical approaches to learning mathematics influences the understanding of students' concepts.

This research is motivated by the importance of the ability to understand students' mathematical concepts. Alternative learning to improve these abilities is a learning model of contextual teaching and learning. The purpose of this study was to determine the effect of contextual teaching and learning on the ability to understand mathematical concepts in terms of student motivation. The research design used in this study is Quasi Experimental Design with factorial 2 × 3. Sampling using Cluster Random Sampling technique. The population in this study were all seventh grade students in Bawang 1 State Middle School. The data in this study were obtained from the results of the posttest ability to understand mathematical concepts and student motivation questionnaires. Data processing is done by using the same two-way cell anava calculation followed by the Scheffe 'test and regression test to know the magnitude of the effect. Conclusions from the results of processing the data are 1) The ability to understand mathematical concepts in set material using the contextual teaching and learning learning model provides the ability to understand mathematical concepts that are the same as students with conventional learning models. 2) Students with high motivation have the ability to understand mathematical concepts better than students with low motivation, and students with moderate motivation have the ability to understand the same mathematical concepts as students who have low motivation. 3) There is no difference in students' ability to understand concepts between students who are given a contextual teaching and learning model and conventional on the level of student motivation. 4) Motivation of learning affects the ability to understand students' mathematical concepts in students given the model of contextual teaching and learning. Learning motivation can be used as an alternative to the affective aspect in measuring the ability to understand students' mathematical concepts, especially in set material because motivation affects the ability to understand mathematical concepts of class VII students.
