PENGEMBANGAN E-LKPD BERBASIS PBL (PROBLEM BASED LEARNING) MATERI SISTEM REPRODUKSI MANUSIA UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS SISWA KELAS XI SMA

DEVELOPMENT OF ELECTRONIC STUDENT WORKSHEETS BASED ON PBL (PROBLEM-BASED LEARNING) IN HUMAN REPRODUCTIVE SYSTEM MATERIAL TO TRAIN CRITICAL THINKING SKILLS OF GRADE XI OF HIGH SCHOOL STUDENTS  

Perkembangan teknologi di abad ke-21 menuntut penguasaan keterampilan berpikir kritis yang esensial bagi siswa, namun kemampuan tersebut pada siswa SMA di Indonesia masih rendah. Penelitian ini bertujuan mengembangkan E-LKPD berbasis Problem Based Learning (PBL) materi sistem reproduksi manusia untuk melatihkan keterampilan berpikir kritis siswa berdasarkan aspek validitas dan kepraktisan. Materi sistem reproduksi manusia dipilih karena relevansinya dengan kehidupan sehari-hari siswa dan kompleksitas konseptual yang memerlukan pendekatan pemecahan masalah. Penelitian ini menerapkan metode Research and Development (R&D) dengan model pengembangan 4-D (define, design, develop, disseminate). Data diperoleh melalui validasi ahli, observasi keterlaksanaan, dan angket respon siswa terhadap 24 subjek penelitian kelas XI-1 SMAN 14 Surabaya. Hasil penelitian menunjukkan bahwa E-LKPD terintegrasi fitur interaktif Go-Insight, Go-Think, Come On!, dan Go-Evaluate untuk melatih berpikir kritis (interpretasi, analisis, evaluasi) dinyatakan sangat valid (88,94%) dan sangat praktis berdasarkan observasi keterlaksanaan mencapai 100%, angket respon siswa memperoleh 98,3%. Kesimpulannya, E-LKPD berbasis PBL pada materi sistem reproduksi manusia dinyatakan valid dan praktis untuk melatihkan keterampilan berpikir kritis siswa.

The development of technology in the 21st century requires students to master essential critical thinking skills, yet these abilities remain low among high school students in Indonesia. This study aims to develop a Electronic Student Worksheets based on Problem Based Learning (PBL) on the human reproductive system material to train students' critical thinking skills based on validity and practicality aspects. The human reproductive system material was chosen because of its relevance to students' daily lives and conceptual complexity that requires a problem-solving approach. This study applies the Research and Development (R&D) method with a 4-D development model (define, design, develop, disseminate). Data were obtained through expert validation, implementation observations, and student response questionnaires of 24 research subjects of class XI-1 SMAN 14 Surabaya. The results showed that the Electronic Student Worksheets integrated with interactive features Go-Insight, Go-Think, Come On!, and Go-Evaluate to train critical thinking (interpretation, analysis, evaluation) was declared very valid (88.94%) and very practical based on implementation observations reaching 100%, student response questionnaires obtained 98.3%. In conclusion, PBL-based Electronic Student Worksheets on the human reproductive system material is declared valid and practical for training students' critical thinking skills.
