If teachers incorporate social-emotional learning (SEL) into the daily school routine, they can help students develop the skills and mindsets they need to succeed in school and beyond. SEL skills are developed through interactions with different environments, so it’s important for SEL activities in the classroom to focus on helping students learn, build, and practice skills they can apply at home and in their communities. The SEL Integration Approach provides guidance on how to integrate SEL into academic curriculum and daily classroom routines. This approach can help teachers support students’ development of SEL skills in ways that are applicable across various areas of their lives, more sustainable over time, and flexible to changing goals and priorities across the lifespan. This approach is a powerful resource to support and promote students’ lifelong learning.
