Education is one field where tech solutions have a long way to go. I believe copyright and cost are two issues that need to be thought about carefully in any ed-related technology venture.
For example, I am pretty sure most teachers still do all their lesson planning using word processing software, which is like architects working in MS Paint. Teachers need a well-designed lesson planning tool. That tool needs to be open-source to see widespread use, for a number of reasons.
I am excited to see where ed tech goes in the next 10 or 20 years. Tell us a little more about what you are thinking, and I'd love to share some more specific thoughts.
