Since we've been discussing how technology could cause educational standards to deteriorate, it's worth considering how it could bring education to groups who would not normally be able to access it.
A few of my friends have worked as literacy tutors in prisons. They found that prisoners were often keen to educate themselves, but the workshops tend to focus on the basics of literacy and numeracy, because so many inmates lack key skills. As the article below points out, though, people who are in jail for long periods could benefit from more advanced courses, which will equip them with the skills they need to find fulfilling work once they get out. This is where distance and digital learning could have a really positive social impact, by providing opportunities and purpose, slashing the rate of reoffending after release.
