The UNICEF-Akelius Digital Learning Initiative ('the Initiative') is one of the largest and longest-standing digital learning initiatives implemented by UNICEF. Launched in 2018 and continuing through 2024, this initiative spans various educational settings across 12 countries. Its primary focus is to improve education outcomes through digital learning, with a particular emphasis on second- and foreign-language acquisition for marginalized children and adolescents aged 6-18 years. This report synthesizes six years of experiences and insights from the Initiative, focusing on the factors and conditions that maximize the effectiveness of digital learning. It specifically addresses the often-overlooked challenges and best practices related to technology management in schools and classrooms. By doing so, the report offers five core messages for the implementation of digital learning at a global level, contributing to a broader understanding of the key factors that influence the successful adoption of digital learning in classrooms, including: (1) Digital tools must be relevant and easy to use; (2) Schools need support with managing technology; (3) Teachers require skills for pedagogical integration and training for blended teaching pedagogy; (4) Evidence and learning are essential to improve implementation; and (5) Building partnerships is key for sustainability. This report serves as a guide for implementing agencies (including UNICEF country offices), ministries of education, school leaders and other stakeholders to adopt effective digital learning practices that support teachers and enhance children's time spent learning.
