PENGEMBANGAN E-LKPD BERBASIS LITERASI SAINS UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS PADA MATERI SISTEM PENCERNAAN MANUSIA

DEVELOPMENT OF ELECTRONIC STUDENT WORKSHEETS BASED ON SCIENTIFIC LITERACY TO PRACTICE CRITICAL THINKING SKILLS ON HUMAN DIGESTIVE SYSTEM MATERIALS

Keterampilan berpikir kritis merupakan kompetensi yang dibutuhkan oleh setiap individu di era globalisasi. Upaya melatihkan keterampilan berpikir kritis salah satunya dengan menerapkan pembelajaran berbasis literasi sains. Salah satu materi yang dapat diajarkan menggunakan pembelajaran berbasis literasi sains adalah Materi Sistem Pencernaan Manusia. Penerapan literasi sains dalam pembelajaran Materi Sistem Pencernaan bertujuan untuk membangun pemahaman peserta didik mengenai sistem pencernaan dan hubungannya dengan masalah-masalah kontekstual yang didukung oleh penggunaan Lembar Kerja Peserta Didik Elektronik (E-LKPD) berbasis liveworksheet. Penelitian ini bertujuan untuk menghasilkan E-LKPD literasi sains pada materi sistem pencernaan yang dapat melatihkan keterampilan berpikir kritis yang layak berdasarkan validitas dan kepraktisan. Penelitian ini menggunakan model pengembangan ADDIE  (Analysis, Design, Development, Implementation, dan Evaluation). E-LKPD yang dikembangkan dilakukan uji coba terbatas pada 20 peserta didik kelas XI-1 SMA Negeri 12 Surabaya. Parameter penelitian ini yaitu validitas E-LKPD yang ditinjau berdasarkan penilaian ahli dan kepraktisan E-LKPD yang ditinjau berdasarkan keterlaksanaan penerapan E-LKPD serta respons peserta didik. Hasil penelitian menunjukkan E-LKPD yang dikembangkan dinyatakan valid dengan skor validitas syarat didaktik 96%, syarat teknik 98%, syarat konstruksi 88%, dan kesesuaian langkah pembelajaran 96%. Hasil kepraktisan berdasarkan keterlaksanaan penerapan E-LKPD sebesar 98,75% dan respons peserta didik sebesar 96,94%. Dengan demikian, E-LKPD yang dikembangkan terkategorikan valid dan praktis sehingga layak digunakan dalam pembelajaran.

Critical thinking skills were competencies needed by each individual in the era of globalization. One efforts to train critical thinking skills was by applying science literacy-based learning. One of the materials that could be taught using science literacy-based learning was the Human Digestive System Material. The application of science literacy in the learning of Digestive System Materials aimed to built students' understanding of the digestive system and its relationship with contextual problems which was supported by the use of liveworksheets-based Electronic Student Worksheets. This research aimed to produce E-LKPD science literacy on digestive system materials to train proper critical thinking skills based on validity and practicality. This research used the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The Electronic Student Worksheets that had been developed was limited to 20 students in class XI-1 of SMA Negeri 12 Surabaya. The parameters in this study were the validity of E-LKPD, which was reviewed based on expert assessment, and the practicality of E-LKPD, which was reviewed based on the implementation of E-LKPD and student responses. The results of the study showed that the Electronic Student Worksheets developed was declared valid with a validity score of 96% for didactic requirements, 98% for technical requirements, 88% for construction requirements, and 96% for the suitability of learning steps. The results of practicality based on the implementation of Electronic Student Worksheets were 98.75%, and the response of students was 96.94%. Thus, the Electronic Student Worksheets developed was categorized as valid and practical, so it was suitable for use in learning.
