Abstract

This study aims at analyzing students' mathematics communication ability in solving word-context problems in the topic of Linear Equation System with Two Variable and describing students' profiles in each level of mathematics communication ability in solving word-context problems in the topic of Linear Equation System with Two Variable using Polya steps. This study is a descriptive qualitative study involving 20 students of grade 8th. The data collection was conducted by using observation, test, interview, and documentation. The data analysis was conducted in three stages, namely data reduction, data display, and conclusion drawing. The results showed that: (1) Students at the low level of mathematics communication ability were only able to complete some Polya steps. The step of understanding the problem, compiling, and carrying out the plan was done poorly. Whereas the action of checking the answers was not completed. (2) Students at the level of mathematics communication ability can write down steps to understand the problem quite well. However, the stages of devising a plan, carrying out the plan, and re-checking answers cannot be done well. (3) Students at a high level of mathematics communication ability can perform the four steps of Polya even though there are still shortages in doing the calculations to get answers.

Abstract

Kurangnya penggunaan bahan ajar dalam proses belajar mengajar di era pandemi COVID-19 mengakibatkan rendahnya motivasi belajar peserta didik dan menurunkan prestasi belajar peserta didik. Penelitian ini bertujuan  untuk mengembangkan Lembar Kerja Peserta Didik materi himpunan dengan menggunakan pendekatan Realistic Mathematics Education untuk mendukung pembelajaran daring di era pandemi COVID-19. Penelitian ini menggunakan model Borg and Gall dengan modifikasi yang terdiri dari tujuh  tahapan, yaitu penelitian dan pengumpulan data, perencanaan produk, pengembangan produk awal, validasi produk awal, merevisi produk II, uji coba lapangan, merevisi produk II. Penelitian ini melibatkan seorang ahli media, seorang ahli materi, dan sepuluh siswa di sebuah SMP negeri di Sragen, Jawa Tengah, Indonesia. Data dikumpulkan melalui kuesioner. LKPD divalidasi oleh seorang ahli materi dan seorang ahli media. Selanjutnya, respon peserta didik dievaluasi untuk menentukan kelayakan dari LKPD. Dari hasil penelitian diperoleh bahwa LKPD berbasis Realistic Mathematics Education pada materi himpunan kelas VII untuk mendukung pembelajaran daring di era pandemi COVID-19 telah valid isi, tujuan, kesesuaian pembelajaran, teknis, desain dan sangat valid dengan total rata-rata skor yang diperoleh dari validator ahli media 3,11 dan dari ahli materi memperoleh skor rata-rata 3,50 dengan kategori sangat layak. Serta pada tahap uji coba lapangan memperoleh skor rata-rata penilaian siswa 3,49 dan dikategorikan sangat layak.
