<![CDATA[Low cognitive learning outcomes among students in mathematics indicate a need for a learning model capable of enhancing active participation and learning motivation. This study aims to improve students' cognitive learning outcomes by implementing the Teams Games Tournament (TGT) cooperative learning model supported by "Smart Board" media. The study employed Classroom Action Research (CAR) methodology, conducted over two cycles comprising the stages of planning, implementation, observation, and reflection. The subjects were 27 students from class II-B at SD Islam Sultan Agung 01 Semarang. Data collection techniques included learning outcome tests, observation, and documentation. Data analysis was performed using both quantitative and qualitative descriptive methods. The results indicate that the implementation of the TGT cooperative learning model supported by Smart Board media successfully improved students' cognitive learning outcomes. The average score rose from 64.32 to 84.06, while the learning mastery rate increased from 37.04% to 85.19%. These findings demonstrate that the TGT cooperative learning model supported by Smart Board media is effective in enhancing students' cognitive learning outcomes in mathematics. Therefore, this learning model serves as a viable alternative for creating an active, enjoyable, and student-centered learning environment.]]>
