Abstract

Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Peserta Didik (LKPD) berbasis discovery learning pada mata pelajaran IPAS, khususnya materi rotasi Bumi untuk siswa kelas VI sekolah dasar. Pengembangan ini dilatarbelakangi oleh rendahnya kemampuan berpikir kritis siswa serta keterbatasan media pembelajaran yangmenstimulasi keterlibatan aktif siswa. Model pengembangan yang digunakan adalah ADDIE (Analysis, Design, Development, Implementation, Evaluation). LKPD dikembangkan melalui pendekatan saintifik dan berbasis aktivitas eksploratif yang memungkinkan siswa membangun pemahaman melalui proses penemuan. Hasil validasi dari ahli materi, media, dan bahasa menunjukkan bahwa produk sangat layak digunakan. Uji coba terbatas juga menunjukkan adanya peningkatan kemampuan berpikir kritis siswa setelah menggunakan LKPD ini. Dengan demikian, LKPD IPAS berbasis discovery learning ini dapat menjadi alternatif solusi pembelajaran kontekstual yang efektif.

Abstract

The critical mathematical thinking ability of elementary school students in Indonesia remains relatively low, as reflected in the results of PISA and ANBK 2022. This is due to instruction that still focuses on rote memorization and the use of learning media that are not yet effective in developing conceptual understanding. This study aims to develop a Student Worksheet (LKPD) based on the Concrete Representational Abstract (CRA) model that is valid, practical, and effective in improving the critical mathematical thinking skills of second-grade elementary students on multiplication material. The research method used is Research and Development (R&D) with the ADDIE development model, which includes the stages of analysis, design, development, and evaluation. Validation was conducted by experts in content, media, and language using the Gregory scale, while practicality was assessed through teacher response questionnaires. The results showed that the CRA-based LKPD met the criteria for high validity and received positive responses from teachers, categorized as "very good." Thus, the LKPD is deemed suitable for use as a learning medium to support the development of students’ critical thinking in basic mathematics learning.
