If you are a faculty or staff member in a higher education institution that teaches GIS, you might want to take a look the new wiki titled “ArcGIS Online Coaching Points for Higher Education“. ESRI states:
ArcGIS Online is an evolving cloud-based GIS software as a service. It is updated several times a year. Educators and Esri staff need a dynamic medium to share problems and advice. This wiki supports the ArcGIS Online education community by providing such a medium.
We encourage education users to post the challenges they face as scenarios in the relevant sections of this wiki. Experienced ArcGIS Online users and Esri staff will respond with advice (i.e., “coaching points”) that help users overcome challenges. To add your scenarios and coaching points to the wiki, simply create an account to gain editing privileges. The team that hosts wiki.gis.com provides plenty of online help.
Probably something to check out before you go to the 2014 Education GIS Conference.
