Research suggests distance education can outperform traditional classroom study

For a growing number of students, going off to class doesn't mean sitting down at a desk in a schoolroom or lecture theatre. It takes place in the virtual world of Second Life, where school's in at an hour that suits you - and you can fly to class.

Second Life is the five-year-old online creation of San Francisco company Linden Lab and, at last count, was inhabited by more than 13 million residents.

Education is just a small part of what goes on there. Essentially, whatever preoccupies people in the real world is also being engaged in by the avatars, or virtual beings, in Second Life.

Especially sex. By one account, about a third of the economic activity - yes, there is a Second Life economy, with Linden dollars as the currency - is to do with sex.

But that hasn't stopped Ohio University from establishing a virtual campus within Second Life. According to a promotional video clip on YouTube, students at the virtual university "thrive in an environment unbridled by space, time or even the laws of physics ...

where the classroom has not just been recreated, but reinvented".

The cyber campus is just one way in which technology is being used for distance learning. Video conferencing remains an important tool for teaching from a distance but podcasts, blogs and wikis - the best-known example of which is Wikipedia - are also increasingly being turned to educational ends.

Traditionalists might protest that there's no substitute for a teacher or lecturer standing in front of the class imparting their knowledge. But research says otherwise.

A United States study, published in the Journal of Communication in 2004, found those who had been educated at a distance slightly outperformed those who'd received the more usual education, when exam results and course grades for more than 70,000 students were looked at. The study's authors concluded that distance education technology wasn't doing students any harm. That's no surprise to Marci Powell, who heads the United States Distance Learning Association.

Powell was in New Zealand last week to meet Ministry of Education officials and Correspondence School, polytech and secondary school teachers.

The issues they confront are the same as those faced by educators in the US, she says, and just as there are some who are wary of adopting new technology, there are others willing to try out whatever's on offer, including various Web 2.0 applications.
