Developing an user-centred project involving the Web 2.0 community : a case study based on video sharing websites (http://e-guitar.univ-reunion.fr/)

The Web 2.0 philosophy has brought new ways of using the web as a content repository and a sharing platform. Non-computer skilled people can now publish their own text, images, videos and/or sounds and take part in communities created around topics they like. It has also brought an opportunity to propose resources to a potentially huge audience. Indeed, a promotional video posted on YouTube can be watched by millions of users. That is why we wanted to know if it was possible to take advantage of this possibility to recruit testers for our music learning tool: our development is user centred, so it is important for us to have it evaluated by lots of testers. Until now, they were recruited in a geographically limited area, i.e Réunion Island. Therefore, we have set up an experiment called “E-guitar Sonar Edition” to gather information about this recruiting opportunity. The idea is thus to design a free downloadable version of our system (originally, it was a DVD), put it on a dedicated web site and have it promoted thanks to video sequences posted on YouTube and Dailymotion, the two majors video Web 2.0 sharing sites, the most appropriate services. This article presents the conditions and the process used. It also deals with the assessment part, the way we gather feedback and finally shows the firsts results. The experiment itself has no limit in time, so it is still currently running. -- Knowledge management ; skill-oriented learning ; user-centred assessment ; music learning ; Web 2.0-based services
