<![CDATA[Bahan ajar yang tersedia belum mampu membuat siswa untuk berpikir aktif, terutama pada materi Teorema Pythagoras. Tujuan penelitian adalah untuk menghasilkan LKPD berbasis Realistic Mathematic Education (RME) yang valid dan praktis. Jenis penelitian yang digunakan adalah penelitian Research and Development dengan mengacu pada model pengembangan Plomp. Instrumen yang digunakan yaitu lembar validasi, lembar angket praktikalitas, dan pedoman wawancara. Uji kepraktisan melibatkan 6 orang siswa kelas VIII di salah satu SMP di Padang. Berdasarkan hasil penilaian validator diperoleh persentase penilaian akhir kevalidan 85% (sangat valid). Nilai akhir uji coba kepraktisan dengan guru dan siswa diperoleh persentase 88,1% (sangat praktis). Disimpulkan bahwa LKPD berbasis Realistic Mathematics Education pada materi Teorema Pythagoras sudah layak digunakan. The available teaching materials have not been able to make students think actively, especially in the Pythagorean Theorem material. The research aims to produce a valid and practical Realistic Mathematics Education (RME)-based LKPD. The type of research used is Research and Development research concerning the Plomp development model. The instruments used were validation sheets, practicality questionnaires, and interview guidelines. The practical test involved 6 grade VIII students of one of the SMP in Padang. Based on the results of the validator's assessment, the percentage of the final validity assessment was 85% (very valid). The final value of practicality trials with teachers and students obtained a percentage of 88.1% (very practical). It was concluded that the LKPD based on Realistic Mathematics Education on the Pythagorean Theorem material was appropriate to use.]]>
