Pengembangan E-LKPD Berbasis Discovery Learning pada Submateri Sistem Pencernaan Manusia untuk Meningkatkan Hasil Belajar Peserta Didik Kelas XI

Development of a Discovery Learning based Electronic Student Worksheet on the Human Digestive System Subtopic to Improve the Learning Outcomes of Eleventh-Grade Students Surabaya

Pembelajaran biologi pada submateri sistem pencernaan manusia memerlukan sumber belajar yang melibatkan peserta didik secara aktif melalui pengamatan dan praktikum. Namun, sumber belajar berbasis Discovery Learning masih terbatas. Penelitian ini bertujuan menghasilkan E-LKPD berbasis Discovery Learning yang valid, praktis, dan efektif. Penelitian pengembangan ini menggunakan model 4D (define, design, develop, dan disseminate). Uji coba terbatas dilakukan pada 30 peserta didik kelas XI MAN 1 Jombang. Instrumen penelitian meliputi lembar validasi, angket respons peserta didik, serta tes pre-test dan post-test. Hasil penelitian menunjukkan validitas sebesar 94,1% dan 93,8% (sangat valid), respons peserta didik sebesar 98,2% (sangat praktis), serta peningkatan nilai rata-rata pre-test dari 42,2 menjadi 88,3 pada post-test. Hasil Paired Sample T-test menunjukkan perbedaan signifikan (Sig. = 0,000 < 0,05) dan nilai N-Gain sebesar 0,78 (tinggi). Dengan demikian, E-LKPD yang dikembangkan dinyatakan valid, praktis, dan efektif.

Biology learning on the human digestive system subtopic requires learning resources that actively engage students through observation and practical activities. However, learning resources based on the Discovery Learning model remain limited. This study aimed to develop a Discovery Learning-based electronic student worksheet that is valid, practical, and effective. This research employed the 4D development model, consisting of the define, design, develop, and disseminate stages. A limited trial was conducted with 30 eleventh-grade students at MAN 1 Jombang. The research instruments included validation sheets, student response questionnaires, and pre-test and post-test instruments. The results showed validity scores of 94.1% and 93.8% (very valid), a student response score of 98.2% (very practical), and an increase in the average pre-test score from 42.2 to 88.3 in the post-test. The Paired Sample t-test indicated a significant difference (Sig. = 0.000 < 0.05), and the N-Gain score was 0.78 (high). Therefore, the developed electronic student worksheet is valid, practical, and effective for biology learning.
