Sari


Penelitian ini bertujuan untuk mendeskripsikan dan menentukan tingkat validitas E-LKPD materi limas untuk mendukung kemampuan pemecahan masalah siswa SMP kelas IX. Penelitian menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE yang meliputi tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Validitas produk dinilai oleh ahli materi, ahli media, dan ahli bahasa berdasarkan aspek isi, konstruk, dan bahasa. Data dianalisis menggunakan teknik deskriptif kuantitatif dengan menghitung persentase skor validasi serta deskriptif kualitatif berdasarkan saran validator. Hasil penelitian menunjukkan bahwa aspek isi memperoleh persentase 91,7%, aspek konstruk 96,7%, dan aspek bahasa 98,3%, dengan rata-rata validitas sebesar 95,6% yang termasuk kategori sangat baik. Dengan demikian, E-LKPD materi limas yang dikembangkan dinyatakan valid dan layak digunakan dalam pembelajaran matematika untuk mendukung kemampuan pemecahan masalah siswa SMP kelas IX.
