I'd like to see genuine educational opportunities - a bit like the OU, but open source. or like the education offered by evening classes from organisations like the WEA.
People who have skipped, or been denied, formal education are often working too hard at low paid jobs to have time to try again. But there is often a few hours a week they can devote to all sorts of displacement activities on the internet.
What about a collaborative education system, where people with suitable qualifications could create small scale teaching material, run seminars, hold closed forums with students and other teachers only admitted, and award small scale certification? Once that was established, then a higher layer could be provided where someone with, say, a dozen of these units under their belt could do a bit more work and glue them together to gain some sort of formal qualification?
Along the way, those in a teaching capacity would also have demonstrated knowledge and commitment and communication skills and would also be entitled to some sort of formalised recognition.
It would matter not if the government were involved or not, as long as users and employers both recognised the outcome as worthwhile evidence of learning, effort, and commitment.
