Merdeka Curriculum is the main gate to developing the potential of elementary school-level students to learn independently through teacher guidance. Currently, the government of the Republic of Indonesia hopes that the Program for International Student Assessment (PISA) results from data in 2018 can be improved. The research objective was to improve the learning outcomes of Pancasila and Civic Education in the aspects of spiritual attitudes, social attitudes, knowledge, and skills of students by applying the EBA learning model to the subject matter of ethnic, social, and cultural diversity in Indonesia. The research subjects were 24 students of class IV of a public elementary school in Padangsidimpuan City, Indonesia. This research used the Kemmis & McTaggart class action research method, which involved planning, acting, observing, and reflecting. Data were collected by using tests, observations, and interviews. The data were analyzed descriptively with qualitative and quantitative approaches. The study's results prove that after applying the EBA learning model, students' learning outcomes have increased from pre-test, post-test I, and II to post-test III with an average score of 86.71 and a completeness percentage of 87.5%.
