Pengembangan E-LKPD Berbasis Eco-STEM untuk Meningkatkan Scientific Creativity Siswa SMP

Abstract

This research aims to develop and determine the validity, practicality, and effectiveness of Eco-STEM based E-LKPD to improve scientific creativity among junior high school students in the subject of substances and their changes. The background of this study is based on the lack of interactive, contextual teaching materials and the lack of learning that emphasizes scientific creativity and environmental issues. In addition, there is also a lack of utilization of digital media in learning. This study uses the ADDIE development model, which consists of five stages: Analyze, Design, Develop, Implement, and Evaluate. The research subjects were 26 students in class VII A MTsN 2 Jember in the odd semester of the 2025/2026 academic year. The results showed that the Eco-STEM based E-LKPD was highly valid, practical, and effective. The validity aspect was categorized as highly valid based on expert assessment of content, language, presentation, and graphics in accordance with the curriculum. The practicality of the E-LKPD obtained an average percentage of 94% (highly practical category), indicating that the E-LKPD can be used well and in accordance with the learning plan. The effectiveness of E LKPD in enhancing scientific creativity is demonstrated by an average N-gain value of 0.60 (moderate category), which indicates a significant improvement in students' scientific creativity skills. The results of the student response questionnaire also show an average score of 92.1% (excellent category) covering aspects of appearance, ease of use, and usefulness. Thus, Eco-STEM based E LKPD is suitable for use as effective innovative teaching material in improving students' scientific creativity and fostering environmental awareness.
