Mike Resnick introduces an interesting language called scratch if you fast forward to about 20 minutes. You can see him building programs using a easy to use language that even children can use. He discusses this language in the context of education and children. It would be a super handy language for developing roomware apps too!

you can download a beta of this software on the scratch site or go to a toy company that sells kits of interactive toys and offers the software free.

Besides that, Mike Renwick gives a really interesting lecture on learning and technology
