The purpose of this study was to determine the trajectory of student learning on ball volume using quaci in Class IX. The research method, using a Validation Study design involving 38 students of class IX SMP Pagaralam PGRI. The stages of design research in learning consist of three phases: preparation for the experiment, design experiment, and retrospective analysis. Learning is carried out through three activities consisting of observing sunflowers, taking sunflower seeds, and wrapping them in accordance with PMRI's approach to ball volume material. The results showed that students could understand the concept of ball volume by completing a series of these activities. In addition, students have their own strategies in solving problems in each activity to express it in abstract form. Conclusion, the use of quaci in learning volumes of ball gives positive results for students in understanding problems related to real life in accordance with the PMRI approach. Keywords: Design Research, Kuaci, PMRI

Desain Pembelajaran Menggunakan Tessellation Berbasis Pendekatan Saintifik pada Materi Translasi dan Refleksi Widiawati Widiawati

The purpose of this study was to determine the role of tesselation in translational and reflection material in developing students' mathematical communication based on a scientific approach. The research method uses design research type validation study involving 30 students of class VII SMP 9 Palembang. The research process produces learning trajectory which contains a series of learning processes in two activities, namely scientific on translational material and scientific on reflection material. Every scientific activity consists of observing, asking, reasoning, trying, and forming networks. The results of the study showed that by providing learning material through a scientific approach, the role of tesselations could help students to carry out mathematical communication so that they could identify translational and reflection material. Therefore, students can understand the concepts of translation and reflection and solve problems related to the material. In conclusion, learning using tessellation with a scientific approach effectively helps students understand the concepts of translation and reflection. Through activities such as observing, asking, reasoning, trying, and forming networks Keywords: Mathematical Communication, Scientific Approach, Tessellation

The purpose of this study was to find out the effect of using PowerPoint animation and Prezi usage on student learning outcomes and compare the differences between student learning outcomes using PowerPoint animation and Prezi. The method used is an experimental method with the Pattern Pretest-Posttest Control Group Design. The population in this study was all undergraduate students of Mathematics Education Study Program semester II at STKIP Muhammadiyah Pagaralam with a sample of two classes. Data collection techniques used are documentation and tests. Test data were analyzed through normality test calculation, homogeneity test, average one test and two average test with calculation using SPSS for windows. The results showed that there is an influence of using PowerPoint animation with ρ value 0.000 and Prezi ρ value 0.032 with student learning results and there is a difference between student learning outcomes using PowerPoint animation with Prezi with ρ value 0.006. In conclusion, there is a significant influence of the use of PowerPoint and Prezi animations on student learning outcomes and there are noticeable differences between the learning outcomes of students using PowerPoint animation and Prezi. The average student learning outcomes using PowerPoint animation are better than Prezi's. Keywords: PowerPoint animation, Learning Outcomes, Prezi
