Abstract

The Kelluwen project implements middle and high-school educational activities where the use of Web 2.0 tools is incorporated to improve collaboration construction, sharing and publishing of the learning outcomes. The Worklog tool, a microblogging space within the Kelluwen platform has an active role in the educational activities. Using probabilistic topic models, correlation analysis and principal component analysis (PCA), we analyzed micropost of 85 class groups participating in the Kelluwen project and found interesting relations of the types of messages posted and other factors such as the teacher participation in the microblog, the rural or urban nature of the schools and other aspects of the educational experience.
