This guide is designed to provide important resources and recommendations to support teacher implementation of digital learning. Digital learning is defined as "any instructional practice that effectively uses technology to strengthen a student's learning experience and encompasses a wide spectrum of tools and practices." This guide will help teachers understand how to use educational technology (EdTech) to support four key goals: (1) Access, Digital Citizenship & Safety, and Privacy & Security; (2) Personalize Learning for Students; (3) Collaborate with Parents and Families to Support Students; and (4) Teacher Professional Learning and Well-Being. Each section provides tips, resources, and questions to help teachers make the best use of EdTech to support students and learn new skills to add to the timeless educator attributes of creativity, caring for students, and ensuring love of learning. This "Teacher Digital Learning Guide" is part of a series of guides including the "Parent and Family Digital Learning Guide" (see ED609021) and "School Leader Digital Learning Guide" (see ED628124) intended to support teachers, parents, families, and leaders in leveraging the capabilities of digital tools and resources for teaching and learning.
