Do you know what the 'Sharing Community' is?
This is a great conversation that I have with 4th and 5th graders. Not only can we discuss future technology ideas but ideas about being an innovator, problem solver, and business person. This document includes two links (I prefer to use the 2nd one first) to a dinner conversation where the newest leaders in app creations discuss some of their opinions and struggles in the creation of apps. I recommend viewing the videos prior to showing them to the students so that you can best figure out how to use them. There are also other 'Sharing Community' articles and sites available (these are just my favorites.)
Showing the videos and our conversations usually takes 15-20 minutes. Then I allow the rest of the period (or a 2nd class) to create a Popplet.
When the students are done, I have them use Popplet.com to web a graphic organizer of their ideas. I prefer to use the app instead of the site because the apps are already have the login set.
