This page is from a German media web site, which use graphs and visualization to share education data from the US and the world. Since everyone in the Classroom forum is involved with education I hope you'll all take a moment to look at the information, as well as how the information is presented.
Many of the introductions I've read are posted by people who come from technology backgrounds in the business world or who teach using technology. Thus, I feel many could be introducing young people to sites like these that show various uses of technology to create and share knowledge and influence actions. The map on my graphic highlights high poverty area of Chicago where kids have fewer resources to help them through school and into jobs. Young people, using their own talent and growing ability to communicate ideas, can be the people represented by the YOU in this graphic who mobilize other people to become involved in making more and richer learning resources and opportunities available in high poverty neighborhoods all over the world.
Kids can begin to learn to do this as early as middle school, maybe even younger. If they practice this on an ongoing basis as they go through formal schooling they will have a wide range of skills to apply in work, family and community problem solving for the rest of their lives.
I'm sure some may already be doing this so if you have students using technology in these ways please share the links so a library of these examples can grow and become inspiration for other youth and educators.
