Abstract
This research is motivated by teachers who have not used digital learning media, resulting in low critical reasoning and learning outcomes. The purpose of the research is to develop a design and test the feasibility and effectiveness of augmented reality-based diorama media to improve critical reasoning dimensions and learning outcomes of Pancasila education. This study uses the research and development method, specifically the ADDIE model, to create augmented reality-based diorama media for Pancasila education aimed at fourth-grade students at Public Elementary School (SDN) Kalibanteng Kidul 01 in Semarang City, Central Java. The study found that the media is highly suitable for education, with validation scores of 93.33% from media experts and 98.21% from material experts. The assessment of critical reasoning scored 95.24%. The t-test results supported the hypothesis, showing significant effectiveness with an N-gain score of 0.7901, classifying it as high. Overall, the study concludes that the augmented reality-based diorama media are effective in improving critical reasoning and learning outcomes related to Pancasila principles for these students in class IV, SDN Kalibanteng Kidul 01, Semarang City, Central Java.
