To elaborate a bit:
I think it could work to get a few Maker spaces to offer 2-5 internships to students. These students will work on a project based curriculum to step them through basic electronics, programming, manufacturing, printing, crowd funding & scaling to production.
The class is all the other students in different maker spaces and they connect and share regularly using online tools. The Maker spaces are the infrastructure providers and the students' expert community (in addition to everything that is online).
This doesn't require a lot of resources - Maker spaces take on the number of interns that they can support, curriculum need some curation but exists to a large extend and online tools for collaboration already exist.
This has the potential to reach people who normally won't have access to skills and/or the internet, but this doesn't need to be the initial focus.
Success metrics could be: having a certain number of Maker spaces collaborate, a high completion rate, some financial success (viable marketplace skills or products) ongoing programs after the initial one.
This is by no means an ultimate plan, but if we manage to do something along these lines I would be really happy about it. I think it can bring online and offline together, it can reach a different crowd and it can test peer education as an alternative on a small scale.
@vanessa please weigh in with your suggestions, I know you have many good ones!
