1. Introduction

Social and emotional learning is the process through which we learn to recognize and manage emotions, care about others, make good decisions, behave ethically and responsibly, develop positive relationships, and avoid negative behaviors (Donoso, Collins, & Koechlin, 2014). It is the learning that unites all areas of human life: social, emotional, academic, cognitive, physical, etc. It begins in the first year of life and lasts a lifetime. School may play a specific role in its development.
