Teacher-centered learning practices have limited students’ active participation in the learning process. Therefore, a learning model that actively engages students through environmental project activities is needed. This study aimed to determine the effect and effectiveness of the environmental project-based Social Studies learning model on students’ ecological awareness, collaboration, and social understanding. The study employed a quantitative approach using a quasi-experimental design with the Nonequivalent Control Group Design. The research was conducted at MIN 2 Sleman involving an experimental class and a control class, each consisting of 27 students. Data were collected using an ecological awareness questionnaire, a collaboration questionnaire, and a social understanding test. The data were analyzed using the Paired Samples t-test, Independent Samples t-test, and N-Gain analysis. The findings indicate that the environmental project-based Social Studies learning model was effective in improving students' ecological awareness, collaboration, and social understanding. The results of the Paired Samples t-test showed that ecological awareness obtained a t-value of -325.000 with p < .001, collaboration obtained a t-value of -42.466 with p < .001, and social understanding obtained a t-value of -4.576 with p < .001, indicating significant differences between the pretest and posttest scores in the experimental class. The results of the Independent Samples t-test revealed that ecological awareness obtained a t-value of 5.420 with p < .001, collaboration obtained a t-value of 7.391 with p < .001, and social understanding obtained a t-value of 2.306 with p = .025, indicating significant differences between the experimental and control groups. Furthermore, the N-Gain analysis showed scores of 0.636 for ecological awareness, 0.644 for collaboration, and 0.464 for social understanding, all of which fall into the moderate category. Therefore, the environmental project-based Social Studies learning model is effective in enhancing students' ecological awareness, collaboration, and social understanding.371.36 Metode Pengajaran, Metode Pembelajaran2026-06-15UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
