Five Recommended Readings?

One of the Associate Deans at my workplace has asked me to recommend five readings (e.g., books, articles, blogpost, etc.) that would help inform his understanding of current changes regarding social networks, knowledge, and technology in education. Rather than develop the list alone, I thought it appropriate to (at least attempt to) crowdsource responses from individuals in my network.

So, what readings would you recommend to an educational leader responsible for faculty development in a teacher education program? Any responses are greatly appreciated.
