Abstract

AbstrakSalah satu tujuan utama pembelajaran matematika adalah untuk meningkatkan kemampuan komunikasi matematis karena kemampuan ini sangat penting untuk menyelesaikan berbagai masalah matematika. Faktanya kemampuan komunikasi matematis peserta didik di SMP Muhammadiyah 9 Yogyakarta masih termasuk dalam kriteria rendah berdasarkan hasil tes tertulis. Penelitian ini bertujuan untuk mengembangkan LKPD berbasis Realistic Mathematics Education untuk meningkatkan kemampuan komunikasi matematis peserta didik. Penelitian ini merupakan penelitian R&D dengan menggunakan model ADDIE. Instrumen yang digunakan adalah instrumen validasi, angket respon peserta didik, dan soal pretest dan posttest. Berdasarkan uji validitas, LKPD berbasis RME termasuk dalam kategori baik dari segi materi dengan skor rata-rata 113 dan sangat baik dari segi media dengan skor rata-rata 83. Berdasarkan angket peserta didik, LKPD berbasis RME termasuk dalam kategori baik dengan skor rata-rata 54,38 yaitu praktis. Berdasarkan hasil analisis nilai posttest kelas eksperimen dan kelas kontrol, LKPD berbasis RME efektif digunakan untuk meningkatkan kemampuan komunikasi matematis peserta didik. AbstractOne of the main goals of learning mathematics is to improve mathematical communication skills because these skills are very important for solving various mathematical problems. The mathematical communication skills of students at SMP Muhammadiyah 9 Yogyakarta are still included in the low criteria based on written test results. This research aims to develop Realistic Mathematics Education-based LKPD to improve students' mathematical communication skills. This research is an R&D research using the ADDIE model. The instruments used are validation instruments, student response questionnaires, and pretest and posttest questions. Based on the validity test, the RME-based LKPD is included in the good material category with an average score of 113 and very good in terms of media with an average score of 83. Based on the students' questionnaire, RME-based LKPD is included in the good category with an average score of 54.38, which is practical. Based on the results of the analysis of posttest scores of experimental and control classes, RME-based LKPD is effectively used to improve students' mathematical communication skills.

Abstract

This research is motivated by the need for teaching materials that are suitable for use in the 21st century, such as utilizing technology in using teaching materials for classroom learning. The use of teaching materials such as worksheets at SMP Muhammadiyah 9 Yogyakarta has implemented a scientific approach but has not been combined with the use of technology. The use of technology in learning is very diverse and can be realized in various supporting applications, one of which is flipbooks. Therefore, it is necessary to use scientific worksheets using the flipbook application. This research designs scientifically based flip worksheets for the subject Systems of Linear Equations in Two Variables that are valid and practical at SMP Muhammadiyah 9 Yogyakarta. Research and Development Methods using the ADDIE model will help achieve the objectives of this research accurately. With the support of instruments such as subject matter experts, media experts, and input from class VIII students, the development of flip worksheets produced very valid results in terms of content and media, with percentages of 94.23% and 90.00% respectively. Meanwhile, for the practical aspect, students gave a percentage of 72.60%, categorizing flip worksheets that were designed as practical.
