<![CDATA[This classroom action research aimed to improve fifth-grade students’ skills in solving mathematical word problems by implementing the cooperative learning method of Teams Games Tournament (TGT), modified with the Realistic Mathematics Education (RME) approach. The study was carried out in two cycles, each consisting of the stages of planning, implementation, observation, and reflection. Data were collected through observations, written tests, and documentation, and were analyzed descriptively. The results showed that students demonstrated improved understanding and greater accuracy in solving word problems. Their participation and enthusiasm in learning activities also increased significantly. These findings indicate that the modified TGT method combined with the RME approach is an effective and engaging strategy for enhancing students’ mathematical problem-solving abilities in the classroom.]]>
