Abstract

This study aimed to design and develop an intertextual e-module on molecular geometry to overcome limitations related to learning resources and instructional time in schools. The development process followed the ADDIE framework up to the development phase. The e-module was constructed using an intertextual approach that connects macroscopic, submicroscopic, and symbolic representations, thereby facilitating students’ conceptual mastery and fostering critical thinking skills. Validation results revealed that the developed module demonstrated excellent validity, with an average Aiken’s V coefficient of 0.994. The characteristics assessment showed that the self-contained, stand-alone, adaptive, pedagogical, multimedia-integrated, and intertextual features each achieved a perfect Aiken’s V score of 1.000. Furthermore, the self-instructional and user-friendly dimensions obtained scores of 0.992 and 0.972, respectively. Expert evaluations also confirmed strong validity across content (0.844), instructional design (0.960), language (0.808), and media (0.910) aspects. Overall, the findings indicate that the e-module is suitable for implementation as a learning resource and has the potential to improve students’ conceptual mastery and critical thinking skills in molecular geometry.

Abstract

Keterampilan berpikir kritis merupakan kompetensi penting dalam pembelajaran kimia. Penelitian ini bertujuan menganalisis karakteristik, metode penelitian, dan efektivitas e-modul dalam meningkatkan keterampilan berpikir kritis. Metode yang digunakan adalah Systematic Literature Review (SLR) dengan tahapan PRISMA. Sebanyak 13 artikel yang diterbitkan pada tahun 2021–2026 dianalisis secara deskriptif. Hasil kajian menunjukkan bahwa e-modul didominasi oleh model Problem Based Learning (PBL) dengan berbagai inovasi, seperti STEM, etnokimia, guided inquiry, dan eksperimen virtual. Metode penelitian yang paling banyak digunakan adalah Research and Development (R&D). Seluruh penelitian menunjukkan bahwa e-modul efektif meningkatkan keterampilan berpikir kritis pada kategori sedang hingga tinggi. Dengan demikian, e-modul berpotensi menjadi bahan ajar digital yang mendukung pengembangan keterampilan berpikir kritis dalam pembelajaran kimia.
