Development of Environmental Awareness-Based Geography Learning Modules to Improve Environmental Awareness of Grade Xi Students

Environmental education plays a crucial role in shaping students' ecological awareness; however, classroom learning practices are still dominated by conventional approaches that overlook the affective aspects. This study aims to develop and test the effectiveness of context-based Geography learning modules on the topic of Environment as a Sustainable Living Habitat in increasing students' environmental awareness. The research method employs a research and development (R&D) approach, utilizing the ADDIE model, with 104 grade XI students at SMAN 4 Kotabumi serving as research subjects. Data were collected through environmental attitude questionnaires, learning outcome tests, observations, and interviews, then analyzed by instrument validity and reliability tests, paired t-tests, N-Gain, and thematic analysis using SPSS and NVivo software. The results of the study showed that the modules developed were declared very feasible based on expert validation, with an average score of 4.42. The responses of students and teachers demonstrated a high level of attractiveness and relevance, while the t-test results showed a significant increase in environmental care, from an average score of 63.3 in the pretest to 82.3 in the posttest, with an N-Gain of 0.62 (medium to high category). This study concludes that the learning modules developed are effective in improving students' environmental awareness attitudes, as well as providing theoretical contributions in strengthening ecopedagogy-based education and practical contributions in the form of teaching materials that can be implemented in the Independent Curriculum.
