Foster multilingual learners' academic success, wellbeing, agency, and belonging. Though multilingual learners (MLs) comprise nearly 25% of the school-age population, the most widely-used social emotional learning (SEL) frameworks and programs lack an intentional focus on these students' unique strengths and challenges. To foster MLs' academic success and wellbeing, educators must consider students' cultures, languages, assets, expectations, norms, and life experiences when integrating SEL practices. In this groundbreaking book, the authors break down how each of the five competencies in the Collaborative for Academic, Social, and Emotional Learning (CASEL) SEL framework can be implemented with ML success in mind. Their practical and engaging guide provides SEL considerations that are unique to MLs, relevant research, easy-to-implement educator actions, and tools to seamlessly integrate SEL practices into content and language instruction. Additional features include tools and practical strategies educators can apply immediately; programmatic and systemic considerations that impact SEL for MLs; examples of successful SEL strategies for MLs currently being used in classrooms; ample opportunities for reflection and application in each chapter; and templates to prioritize and integrate SEL for MLs into teaching practices. MLs thrive when they are validated and supported to achieve their goals, empathize with others, build relationships, and make responsible decisions. The essential actions presented in this guide will enable you - regardless of your role or prior experience with SEL - to empower MLs to achieve academic and lifelong success.
