One of the things which I picked up during the ESRI UC this year was the story template with ArcGIS Online. I feel this could be a very good medium to share maps in form of stories or events. I even met one of the high school teacher who was planning to use this for teaching history in her class.After the UC I ended up creating my experience using the template.
You can also incorporate vice over narration for much better educational teaching. I have tried http://www.debbieirwin.com/, hopefully I can share you this quality and good resources for story narration and eLearning.
