My Summer Class- 21st Century Teaching

So I'm just finishing up my summer professional development class. Prior to the class, we did a good deal of reading about PBL from Edutopia as well as looked at the State of Vermont Transformation ideas We have looked at the student NETS, went over a few Web 2.0 tools, and had a lot of time to work on the unit project that we were assigned. Our assignment was to adapt one of our units to make it more 21st century. The teachers (the tech integrationist from our district and from a neighboring one) wanted us to make our lessons as transformative as possible. I choose to work on Latin America unit. Here is a link to my project (has my KUD, skills list, NETS, and pacing guide for the unit). Please give me some feedback on it.
