Abstract


Penelitian ini bertujuan mengetahui kelayakan lembar kerja siswa, melatihkan keterampilan proses sains siswa, serta hasil belajar siswa. Desain penelitian ini menggunakan model pengembangan 4-D, tetapi tahap penyebaran tidak dilakukan. Instrumen yang digunakan adalah lembar telaah, validasi, respon siswa, evaluasi keterlaksanaan guided inquiry, evaluasi keterampilan proses sains, tes keterampilan proses sains, evaluasi hasil belajar, serta pengamatan aktivitas siswa. Uji coba terbatas dilakukan terhadap 12 siswa kelas XI SMAN 16 Surabaya. Metode yang digunakan adalah angket, evaluasi, dan pengamatan. Hasil validasi menyatakan lembar kerja siswa sangat layak berdasarkan kriteria isi, bahasa, penyajian, kegrafikan, guided inquiry, dan keterampilan proses sains dengan persentase 84,63%; 89,06%; 81,25%; 84,25%; 85,42%; 78,13%. Siswa memiliki keterampilan proses sains yang mulai membudaya dengan persentase 91,66%, dan hasil belajar yang baik dengan ketuntasan 80%.


Kata Kunci: lembar kerja siswa, guided inquiry, keterampilan proses sains, hasil belajar, asam-basa, kelayakan.
