Reading a recent article from EdTech Web made me think about how digital learning is a normal cultural immersion for anyone growing up in the K-12 school environment of today.  Educators are challenged by keeping the attention of students who are bombarded with dynamic living content.  The issue seems to be assessing the effectiveness of any content and having intentional checkpoints put in place, whether they are embedded into the actual digital content or having a supplemental resource that would check for comprehension. Digital Learning Tree has a very wide range of tools and many flexible options for not only presenting digital content but also building customized assessment modules.
