What do 21st Century Skills Really Mean?

This important report from the National Research Council of the National Academies of Science in Washington has identified 3 categories of 21st Century Skills..... 

• Cognitive Skills,
• Interpersonal Skills,
• Intrapersonal Skills. 

The questions we need to ask revolve around how schooling (including T1) can develop them. Conversely, how do we discourage them? How can we as teachers help our students develop these important skills, especially the last two?  How do we unintentionally discourage this development?
This article is very insightful partly because it takes the skills into real world application.  Important for all of us to consider.  Ideas anyone?
