Abstract

This research aims to develop contextual teaching materials based on the "BESTARI" eco-environment framework to enhance the critical thinking skills of 5th-grade students on the topic "My Earth." Utilizing the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), the study was conducted at SD Negeri 4 Aceh Tengah. Data collection involved expert validation, practicality questionnaires, and pretest-posttest instruments. Results indicate that the materials achieved a "Very Valid" status (90.6%) and "Very Practical" status (92.3%). Effectiveness tests demonstrated a significant improvement in critical thinking, with a student mastery rate of 88.7%. This study implies that integrating local environmental values into learning curriculum can effectively bridge abstract concepts with analytical reasoning. It provides a scalable model for educators to foster higher-order thinking through contextualized, environmentally conscious learning.
