Based on the results of observations and interviews, fourth-grade students at SDN Karangbesuki 1 demonstrated low participation in classroom learning, tended to be passive, had difficulty maintaining focus during lessons, and experienced challenges in understanding the topic of the formulation of Pancasila. In addition, the learning process was predominantly teacher-centered, resulting in limited student engagement. This study aimed to improve students' learning outcomes on the topic of the formulation of Pancasila through the implementation of the Student Teams Achievement Division (STAD) cooperative learning model integrated with Wordwall. This study employed Classroom Action Research (CAR) conducted in two cycles. The research subjects consisted of 28 fourth-grade students at SDN Karangbesuki 1. Data were collected through tests, observations, interviews, and documentation. The data were analyzed using both quantitative and qualitative techniques. The findings indicated a consistent improvement in students' learning outcomes across each cycle. During the pre-cycle stage, the average student score was 60.36, with a classical learning mastery percentage of 7.14%. After the implementation of the intervention in Cycle I, the average score increased to 90.36, while the classical learning mastery percentage reached 92.86%. Furthermore, in Cycle II, the average score improved to 96.43, and the classical learning mastery percentage reached 100%. These findings indicate that the implementation of the Wordwall-assisted STAD cooperative learning model effectively improved both students' learning outcomes and their engagement in Pancasila Education.
