PAUSE--LET’S REFLECT: Blended learning has evolved throughout the 21st century, but it’s hard to track it when you’re knee deep in it every day. So, iNACOL took a look at the landscape to identify the most popular blended models in its latest report, The Evolution of Online and Face-to-Face Education from 2008–2015. With district case studies in tow, the report identifies 4 lessons that districts should consider when implementing blended tools and programs. (Think preventing problems with PD, and creating a school culture that will allow for snags in blended learning implementation.)
