During Units 1-3, we2019ve explored many of the big ideas about K-12 digital learning to help you define the vision and goals for your own initiatives. We2019ve also looked at many school and district initiatives, and the lessons learned from them, to inform your understanding of the challenges involved in creating a successful digital learning transition and strategies for addressing those challenges. The essential questions for this unit are: (1) How can we effectively communicate our goals for digital learning, and the challenges to meeting those goals, with the members of our school or district community? (2) What new insights and ideas have we gained about digital learning that will impact our work?
