I had use  SEL in my classroom. I always ask my students how they feel before started the class and free writing can also improve their self awareness. After, they know their feeling, we advice to stay calm in the exam or breath instead of angry which make them develop their self control. Sometimes, we let them talk with their partner to share their experience and feelings so that they listen to their friend and which improve their point of view instead of only care their perspective. We also tell the students, when never they do team work, all the people had to participated and choose the things that groups agree to do it instead of one student control everything.
