Abstract
Penelitian ini adalah penelitian pengembangan Lembar Kerja Peserta Didik (LKPD) berbasis Masalah untuk materi Reaksi Redoks telah diuji cobakan di kelas X SMA Negeri 15 Palembang. Model pengembangan yang digunakan adalah model ADDIE dan evaluasinya menggunakan evaluasi formatif Tessmer. Tahap evaluasi formatif Tessmer dalam penelitian ini adalah self evaluation , expert review , one-to-one , small group , dan field test eveluation . Hasil penelitian menunjukkan bahwa lembar kerja peserta didik berbasis Problem Based Learning termasuk kategori valid dan layak digunakan. Tahap expert review didapatkan hasil validasi pedagogik sebesar 3,80 (valid), hasil validasi materi sebesar 4,28 (sangat valid), dan hasil validasi desain sebesar 4,00 (valid). Tahap one-to-one diperoleh skor kepraktisan sebesar 3.52 (praktis), dan pada tahap small group diperoleh skor 4,71 (sangat praktis). Field test evaluation menunjukkan bahwa lembar kerja peserta didik berbasis Problem Based Learning dinyatakan efektif dengan N-gain score tinggi sebesar 0,83. Hasil penelitian menunjukkan bahwa lembar kerja peserta didik materi reaksi redoks pada pelajaran kimia dikelas X SMA Negeri 15 Palembang berbasis Problem Based Learning valid, praktis dan efektif. Penelitian selanjutnya disarankan untuk melakukan pengembangan bahan ajar kimia dengan berbasis masalah pada materi lain.
