Last week in Cupertino, I saw the iPhone apps download screen and I was shocked. People around has a powerful machine in their bags and it is a lot of educative potential. Only imagine how many activities you can plan for your students! An how many else they could design and produce. The Stanford course about how develop apps for the iPhone is only part of a global movement to build a huge plataform of knowledge building. Apps Store is like a social lab offering solutions for the most bizarre problems, but an amazing showroom to the new ideas and concepts.
