PENGEMBANGAN LKPD BERBASIS PROJECT BASED LEARNING MATERI PERUBAHAN LINGKUNGAN UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS SISWA KELAS X SMA
DEVELOPMENT OF LKPD BASED ON PROJECT BASED LEARNING ON ENVIRONMENTAL CHANGES TO TRAIN CRITICAL THINKING SKILLS OF X-CLASS HIGH SCHOOL STUDENTS
Fokus penerapan Kurikulum Merdeka termasuk dalam kompetensi abad ke-21 seperti literasi digital, kreativitas, komunikasi, berpikir kritis, pemecahan masalah, dan kolaborasi. Berpikir kritis sangat perlu untuk dilatihkan karena dengan berpikir kritis, siswa dapat diasah kemampuannya untuk mengamati berbagai situasi, membuat pertanyaan, merumuskan hipotesis, menjalankan observasi, mengumpulkan data, sebelum sampai pada kesimpulan. Tujuan penelitian ini mendeskripsikan validitas, kepraktisan, dan keefektifan LKPD perubahan lingkungan berbasis Project Based Learning. Penelitian ini mengikuti langkah-langkah model 4D (Define, Design, Develop dan Disseminate) dalam pengembangannya. Metode pengumpulan data yang digunakan pada penelitian ini adalah metode validasi, observasi keterlaksanaan pembelajaran, angket respon, dan tes. LKPD yang dikembangkan memiliki kriteria sangat valid berdasarkan kriteria aspek penyajian, isi, dan kebahasaan rata-rata sebesar 92%. LKPD dinyatakan praktis berdasarkan hasil observasi keterlaksanaan pembelajaran sebesar 75% dan angket respon peserta didik sebesar 95,77% dengan kategori sangat praktis. LKPD dinyatakan efektif, diperoleh dari nilai hasil tes peserta didik yaitu ketuntasan tes keterampilan berpikir kritis dengan hasil N-gain mencapai 0,75 (kategori tinggi). Dengan demikian, dapat dinyatakan bahwa LKPD berbasis Project Based Learning pada materi perubahan lingkungan untuk melatihkan keterampilan berpikir kritis yang dikembangkan valid, praktis, dan efektif..
Kata Kunci: LKPD, Project Based Learning, berpikir kritis,
The focus of implementing Merdeka Curriculum included 21st century competencies such as digital literacy, creativity, communication, critical thought, problem solved, and collaboration. Critical thought was very necessary to trained because with critical thinking, students could have honed in their ability to observed various situations, made questioned, formulate hypotheses, carried out observations, collected data, before arrived at conclusions. The purpose of this studied was to described the validity, practicality, and effectiveness of Project Based Learning-based environmental changed LKPD. This researched followed the stepped of the 4D model (Define, Design, Developed and Disseminate) in its development. The data collection methods used in this studied was validation method, observation of learned implementation, response questionnaire, and tested. The developed LKPD had very valid criteria based on the criteria for the aspects of presentation, content, and language on average of 92%. LKPD declared practical based on the results of observations of learned implementation of 75% and a student response questionnaire of 95.77% with a very practical category. LKPD declared effective, obtained from the tested scores of students, namely the completeness of the critical thought skills tested with theN-gained results reached 0.75 (high category). Thus, it could have stated that the Project Based Learning-based LKPD on environmental changed material to trained critical thought skills developed was valid, practical, and effective.
