PENGEMBANGAN E-LKPD BERBASIS DISCOVERY LEARNING PADA MATERI EKOSISTEM KELAS V SD

Abstract

ABSTRACT

The limited use of digital learning materials in IPAS instruction at SD Negeri 1 Betung indicates the need for learning resources that encourage students not merely to receive information but to engage in the process of concept discovery. In response to this need, this study developed an Electronic Student Worksheet (E-LKPD) based on Discovery Learning through the Liveworksheets platform for the topic of Harmonious Ecosystems. The product was developed using a Research and Development (R&D) approach guided by the ADDIE model, comprising Analyze, Design, Development, Implementation, and Evaluation. A total of 21 fifth-grade students participated in the product implementation. The quality of the E-LKPD was examined through expert validation, student responses, and learning achievement tests, with the data analyzed descriptively using percentages. The developed product achieved a validity score of 91.49% (highly valid) and a practicality score of 94.06% (highly practical). In the field implementation, 19 of 21 students achieved mastery, resulting in a classical mastery rate of 90.48%. Integrating the six Discovery Learning stages into Liveworksheets activities provided a structured learning experience that enabled students to observe, investigate, process information, and construct understanding more independently. The resulting E-LKPD can therefore serve as an alternative digital learning resource for more active and student-centered IPAS instruction in elementary schools.

ABSTRAK

Keterbatasan penggunaan bahan ajar digital dalam pembelajaran IPAS di SD Negeri 1 Betung memperlihatkan perlunya perangkat belajar yang dapat mengarahkan peserta didik tidak sekadar menerima materi, tetapi terlibat dalam proses menemukan konsep. Atas kebutuhan tersebut, penelitian ini mengembangkan E-Lembar Kerja Peserta Didik (E-LKPD) berbasis Discovery Learning melalui platform Liveworksheets pada materi Ekosistem yang Harmonis. Produk dirancang dengan pendekatan Research and Development (R&D) menggunakan model ADDIE, yang mencakup Analyze, Design, Development, Implementation, dan Evaluation. Sebanyak 21 peserta didik kelas V terlibat dalam penerapan produk. Kualitas E-LKPD ditelaah melalui validasi ahli, respons peserta didik, dan tes hasil belajar, dengan data dianalisis secara deskriptif menggunakan persentase. Hasil pengembangan memperlihatkan tingkat validitas 91,49% (sangat valid) dan kepraktisan 94,06% (sangat praktis). Pada penerapan lapangan, 19 dari 21 peserta didik mencapai ketuntasan, menghasilkan ketuntasan klasikal 90,48%. Integrasi enam sintaks Discovery Learning ke dalam aktivitas Liveworksheets memberikan struktur belajar yang memungkinkan peserta didik mengamati, menyelidiki, mengolah informasi, dan membangun pemahaman secara lebih mandiri. E-LKPD yang dihasilkan dengan demikian dapat menjadi alternatif bahan ajar digital untuk pembelajaran IPAS sekolah dasar yang lebih aktif dan berpusat pada peserta didik.
