Pengembangan Game Edukasi Berbasis STEM Berbantuan Construct 2 untuk Mendukung Kemampuan Berpikir Kritis Siswa Pada Materi Ekosistem Kelas V SD

Abstract

The national education system aimed to enhance students’ thinking skills, particularly critical thinking. At the elementary school level, critical thinking was a fundamental skill that supported analysis, evaluation, problem-solving, and systematic reasoning. Therefore, strengthening critical thinking from an early age was essential to prepare students for future challenges. This study aimed to develop a STEM-based educational game using Construct 2 to improve fifth-grade students’ critical thinking skills on the topic of ecosystems. This study employed the ADDIE model for research and development (R&D). Data collection techniques included interviews, questionnaires, and learning outcome tests. The subjects were fifth grade students at SDN Kemuningsari Lor 01. Data analysis techniques included a validity test using the Valpro formula, an effectiveness test using the N-Gain score, and a practicality test based on the SAS formula. The validity test yielded a score of 83.5, indicating that the educational game was highly feasible for use in learning. The effectiveness test produced an N-Gain score of 68%, categorized as moderately effective, based on pre-test and post-test results, showing that the game enhanced students’ critical thinking skills. The practicality test yielded a score of 91.8, categorized as very practical, indicating that the game was easy to implement. Based on the results of the validity, effectiveness, and practicality tests, it can be concluded that the STEM-based educational game was valid, effective, and practical for improving elementary students' critical thinking skills.
