There is no “official” SEL curriculum. But that doesn’t mean it can’t be taught. SEL can be worked into any activity or lesson you teach by looking at what skills you want students to develop through their participation.
The book Becoming the Educator They Need (Robert Jackson, ASCD) has fantastic nuggets you will need to continue your success thus far in the school year. Particularly, chapters three and four dig into developing mindsets of culturally responsive educators and challenges readers to apply that mindset to build strong relationships with students and other staff members. These mindsets are critical if we want to identify and address bias in our own lives.
