A survey describing Oxford University students’ use of Web 2.0 services has been released (Results of the "Online Tool Use Survey" Undertaken by the JISC Funded SPIRE Project).
Here’s a brief description from the "Some Real Data on Web 2.0 Use" posting on TALL Blog.
As part of the JISC funded ‘SPIRE’ project we ran a survey to try to discover which online services people were using and in what manner. We were interested to find out which services were popular and if they were being used for work, for study or socially / for fun. The SPIRE project was originally looking into the possibility of using peer-to-peer technologies in UK HE and FE for informal sharing but switched to a more Web 2.0 focus as it became clear that these types of services where already having an impact on the tertiary education sector. They also appear to be where most of the informal sharing and collaboration is taking place online these days.
