Abstract

Abstrak

Tujuan penelitian pengembangan ini adalah untuk mengetahui kelayakan LKPD IPA tema “Pencemaran Lingkungan” berbasis Problem Based Learning dari beberapa ahli dan guru IPA dan untuk mengetahui besar peningkatan keterampilan berpikir kreatif peserta didik kelas VII setelah menggunakan LKPD IPA berbasis Problem Based Learning. Penelitian ini merupakan penelitian pengembangan model 4-D dengan tahap pendefinisian (define), tahap perancangan (design), tahap pengembangan (develop) dan tahap penyebaran (disseminate). Penelitian ini melibatkan 2 validator ahli dan satu praktisi. Instrumen penelitian yang digunakan dalam penelitian ini meliputi lembar validasi LKPD, angket respon peserta didik, soal pretest-posttest keterampilan berpikir kreatif, lembar observasi keterampilan berpikir kreatif, dan lembar keterlaksanaan pembelajaran berbasis Problem Based Learning. Hasil penelitian pengembangan LKPD IPA berdasarkan penilaian validator ahli dan praktisi ditinjau dari kelayakan isi, kebahasaan, penyajian, dan kegrafikan memperoleh skor rata-rata 3,6 (kategori sangat baik) sehingga layak digunakan dalam pembelajaran. LKPD IPA hasil pengembangan dapat meningkatkan keterampilan berpikir kreatif dibuktikan dengan gain score sebesar 0,50 dengan kategori sedang dan dengan hasil observasi keterampilan berpikir kreatif peserta didik meningkat 5%.
