<![CDATA[The Solar System is an abstract and difficult concept for students to understand. On the other hand, conceptual understanding and digital literacy are competencies that students must have in the 21st century. The purpose of this study was develop and analyze STEM-PjBL based Augmented Reality for enhancing students' conceptual understanding and digital literacy in Solar System concept. Quasi-experimental research with pretest and posttest group design was utilized in order to answer the research questions in this study. The results of the study showed that STEM-PjBL based AR media were effective in improving students' conceptual understanding with an N-gain score in the experimental class of 0.71 (high criteria) compared to the control class of 0.41 (moderate criteria). The highest conceptual understanding indicators were in inferring and comparing. STEM-PjBL-based AR media was effective in improving students' digital literacy with an N-gain score in the experimental class of 0.57 (moderate criteria) compared to the control class of 0.22 (low criteria). The highest digital literacy indicators are in communication, content creation, and problem solving.]]>
