PENGEMBANGAN LKPD IPAS BERBASIS EXPERIENTIAL LEARNING PADA MATERI BUNYI DAN SIFATNYA UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS KELAS V SD

DEVELOPMENT OF LKPD IPAS BASED ON EXPERIENTIAL LEARNING ON THE MATERIAL OF SOUND AND ITS PROPERTIES TO IMPROVE CRITICAL THINKING SKILLS OF GRADE V ELEMENTARY SCHOOL STUDENTS

Di abad ke-21, siswa dituntut memiliki keterampilan berpikir kritis, salah satunya melalui pembelajaran IPAS. Untuk mendukung pembelajaran yang mendorong keterampilan tersebut, dibutuhkan perangkat ajar yang tepat, seperti LKPD. Namun, LKPD yang digunakan guru masih belum terintegrasi dengan model pembelajaran dan pengembangan berpikir kritis. Penelitian ini bertujuan mengembangkan LKPD IPAS berbasis Experiential Learning pada materi bunyi dan sifatnya guna meningkatkan keterampilan berpikir kritis siswa kelas V SD. Penelitian menggunakan pendekatan Research and Development dengan model ADDIE dan melibatkan 23 siswa kelas V SD sebagai subjek. Hasil pengembangan menunjukkan bahwa LKPD memiliki tingkat kevalidan sangat valid, yaitu 97,5% dan 91,7%. Dari segi kepraktisan, diperoleh skor respon guru dan siswa sebesar 100% dan 95,7%, termasuk kategori sangat praktis. Keefektifan LKPD dibuktikan melalui uji N-Gain dengan rata-rata 0,42 dan uji beda yang menunjukkan pengaruh sangat signifikan. Dengan demikian, LKPD IPAS berbasis Experiential Learning pada materi bunyi dan sifatnya dinyatakan valid, praktis, dan efektif untuk meningkatkan keterampilan berpikir kritis siswa.

In the 21st century, students are required to possess critical thinking skills, one of which can be developed through IPAS learning. To support learning that fosters these skills, appropriate instructional tools such as student worksheets (LKPD) are essential. However, the LKPDs currently used by teachers have not been integrated with learning models and critical thinking development. This study aims to develop an IPAS LKPD based on Experiential Learning on the topic of sound and its properties to improve the critical thinking skills of fifth-grade elementary students. The research employed a Research and Development approach using the ADDIE model, involving 23 fifth-grade students as subjects. The results showed that the developed LKPD was highly valid, with validity scores of 97.5% and 91.7%. In terms of practicality, the student and teacher responses were 95.7% and 100%, indicating a very practical category. Effectiveness was measured through the N-Gain test, with an average score of 0.42, and a significance test that showed highly significant effect. Therefore, the IPAS LKPD based on Experiential Learning is considered valid, practical, and effective in enhancing students’ critical thinking skills.
