This study discusses students' social-emotional learning by combining the small group method to make it easier for students to produce a problem and increase their confidence when expressing their opinions. In this method, students must be active in discussions to produce maximum problem-solving. To obtain and collect data intensively, researchers conducted research using qualitative studies. Based on the data obtained, the Collaborative Social Reasoning approach was successfully applied in class VIII D SMP N 2 Temon. The researcher concluded that using CSR strategies makes students better understand the material, more confident, and more active in participating in learning. They can exchange ideas freely with groups and learn more foreign vocabulary beforehand. In the strategy, the teacher's role is only to be a good student facilitator. The teacher does not fully interfere with students in discussions. Students can also apply their social-emotional vocabulary well. This strategy also creates more positive interactions between students and teachers. Overall, this strategy is suitable for English learning at the secondary school level, especially at SMP N 2 Temon.
