Pengembangan Perangkat Pembelajaran IPA Berbasis Keterampilan Proses Sains Untuk Meningkatkan Kemampuan Berpikir Kritis Siswa SMP

Development of the Science Learning Package Based on the Science Process Skills to Improve the Critical Thinking Skills of the Junior High School Students.

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran IPA berbasis keterampilan proses sains yang layak dengan kriteria valid, praktis, dan efektif untuk meningkatkan kemampuan berpikir kritis siswa SMP. Penelitian ini dilaksanakan dalam dua tahap, yaitu tahap pengembangan perangkat pembelajaran dengan mengadaptasi model 4-D, kemudian dilanjutkan tahap implementasi perangkat di kelas menggunakan rancangan uji coba One-Grup Pretest-Posttest Design. Hasil penelitan menunjukkan bahwa: (1) Perangkat pembelajaran yang dikembangkan terbukti valid, (2) Kepraktisan perangkat pembelajaran ditinjau berdasarkan keterlaksanan pembelajaran termasuk kategori sangat baik dengan nilai rata-rata sebesar 93,75% yang ditunjang keterbacaan LKS dan buku ajar siswa yang tinggi, (3) Kefeektifan perangkat pembelajaran ditinjau berdasarkan peningkatan keterampilan proses siswa dan kemampuan berpikir kritis siswa yang tergolong tinggi dengan skor masing-masing N-gain sebesar 0.72 dan 0.71. Respon siswa terhadap pembelajaran memiliki persentase rata-rata sebesar 90-100%. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa perangkat pembelajaran IPA berbasis keterampian proses sains yang dikembangkan layak digunakan untuk meningkatkan kemampuan berpikir kritis siswa SMP.

This study aimed to produce science learning package based on the science process skill that is worthy of valid, practical, and effective criteria to improve the critical thinking skill of junior high school students. This study was conducted in two stages, namely the development of learning package by adapting the 4-D model, and then continued the implementation stage of the package in the class using the one-group pretest-posttest design. The results of the research show that: (1) The learning package developed are proven to be valid, (2) The practicality of the learning package reviewed based on the learning implementation includes the excellent category with an average score of 93.75% supported by the readability of student worksheets and high student textbooks, (3) The effectiveness of the learning package is reviewed based on the improvement of students' process skills and critical thinking skills classified as high with scores of N-gain of 0.72 and 0.71 respectively. Student responses to learning have an average percentage of 90-100%. Based on the results of this research, it can be concluded that the science learning package based on the science process skills are to be used to improve the critical thinking skills of junior high school students.
