The 5 Cs of 21st Century Learning

So we all know the 4 Cs: Critical Thinking Skills, Creation of Content, Collaboration, and Connections to develop a Personal Learning Community.  (PLC)  But I don't think that's all of them.  I'd like to advocate for another, Curation.  Once students have collected relevant, reliable information, made connections and used them to collaborate on the creation of some project, they need a way to categorize, classify, and store all of this information for later retrieval and sharing of content as needed.  All of the information sources, contacts, and products shouldn't just disappear after the unit, project, or lesson is finished.  All of this information can be used at later dates for reflection, springboards for further learning, or for sharing with others looking for reliable information.  So I officially nominate Collaboration to be included.  Who will second the motion?  Shall we put it to a vote?
