Recently, Michael Horn, founder of Innosight Institute and co-author of "Disrupting Class" presented a webinar titled How Digital Curriculum is Transforming Learning. Here's the link: Michael Horn webinar: Digital Curriculum Transforming Learning
Innosight has also produced a report that shows how three school districts – Auburn (WA), Volusia County (FL) and Wichita Public (KS) – are implementing online learning using curriculum provided by Apex Learning. It offers insight into how the use of digital curriculum is helping districts meet their needs, and provides examples for designing an online learning program.
(While the content is focussed on the content from Apex Learning, and is set in an American context, there are some general principles that provide food for thought.)
