"I, Paul Hamilton, hate App lists. I believe strongly that software, without direction and context, does very little in an educational context. I believe the role of the teacher in the classroom (and out) has never been more crucial."
Now that I have that out of the way let's take a look at 4 Applications that encourage and foster 21st century skills. The 4 C's - Critical Thinking, Communication, Collaboration and Creativity. Remember that the task, context and feedback given to students whilst using these tools is the key ingredient to significant development. Combined with this, software can also be an extremely powerful tool for learning!

2. Critical Thinking - Comic Life
