Abstract

Penelitian ini merupakan penelitian pengembangan (Research and Development) dengan model pengembangan 4D yang memiliki 4 tahapan yaitu, define, design, develop, dan dissemination. Tujuan dari penelitian ini yaitu menghasilkan bahan ajar berbentuk E-LKPD yang valid dan praktis pada materi teorema pythagoras. Subjek penelitian terdiri dari validator ahli, guru matematika di SMP Negeri 87 Jakarta, dan peserta didik kelas IX SMP Negeri 87 Jakarta. Teknik pengumpulan data menggunakan angket dan observasi. Hasil penelitian menunjukkan bahwa produk memperoleh hasil validitas ahli materi dan bahasa sebesar 90,4% dengan kriteria penilaian sangat valid, hasil validitas ahli media sebesar 87,2% dengan kriteria penilaian sangat valid, hasil validitas kepada praktisi sebesar 94% dengan kriteria penilaian sangat valid, hasil uji coba kepada peserta didik kelompok kecil sebesar 89,8% dengan kriteria penilaian sangat praktis, dan hasil uji coba kepada peserta didik kelompok besar sebesar 90,2% dengan kriteria penilaian sangat praktis. Berdasarkan hasil penilaian terhadap produk berupa E-LKPD berbasis PBL dengan materi teorema pythagoras kelas VIII SMP valid dan praktis digunakan dalam pembelajaran matematika. ***** This study is a Research and Development (R&D) project utilizing the 4D development model, which comprises four stages: define, design, develop, and dissemination. The objective of this research was to produce valid and practical teaching materials in the form of an Electronic Student Worksheet (E-LKPD) covering the Pythagorean theorem. The research subjects included expert validators, a mathematics teacher from SMP Negeri 87 Jakarta, and Grade IX students from the same school. Data collection techniques involved questionnaires and observation. The results indicated that the product achieved a content and language expert validity score of 90.4% (rated "very valid"), a media expert validity score of 87.2% (rated "very valid"), and a practitioner validity score of 94% (rated "very valid"). Furthermore, the small-group student trial yielded a score of 89.8% (rated "very practical"), while the large-group student trial resulted in a score of 90.2% (rated "very practical"). Based on these evaluations, the PBL-based ELKPD on the Pythagorean theorem for Grade VIII students is considered valid and practical for use in mathematics instruction
