The average cost of yearly tuition at a private, four-year college in the US this year was $25,143, and for public schools, students could expect to pay $6,585 on average for the 2008-09 school year, according to the College Board. That was up 5.9% and 6.4% respectively over the previous year, which is well ahead of the national average rate of inflation. What that means is that for many people, college is out of reach financially. But what if social media tools would allow the cost of an education to drop nearly all the way down to zero?
Of course, quality education will always have costs involved — professors and other experts need to be compensated for their time and efforts, for example, and certain disciplines require expensive, specialized equipment to train students (i.e., you can’t learn to be a surgeon without access to an operating theater). However, social media can drastically reduce much of the overhead involved with higher education — such as administrative costs and even the campus itself — and open source or reusable and adaptive learning materials can drive costs down even further.
One vision for the school of the future comes from the United Nations. Founded this year by the UN’s Global Alliance for Information and Communication Technology and Development (GAID), the University of the People is a not-for-profit institution that aims to offer higher education opportunities to people who generally couldn’t afford it by leveraging social media technologies and ideas.
