Moodle is a Virtual Learning Environment (VLEs) used extensively in third level education that captures a significant amount of log data on student activity. In this paper we present an analysis of Moodle data that reveals interesting differences in student work patterns. We demonstrate that, by clustering activity profiles represented as time series using Dynamic Time Warping, we can uncover meaningful clusters of students exhibiting similar behaviours. We use these clusters to identify distinct activity patterns among students, such as Procrastinators, Strugglers, and Experts. We see educators as the potential users of a tool that might result from this research and our preliminary analysis does identify scenarios where interventions should be made to help struggling students.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Keywords:||Machine learning; Statistics; Virtual learning environments (VLE)||Other versions:||http://aics2016.ucd.ie/||Language:||en||Status of Item:||Peer reviewed||Conference Details:||24th Irish Conference on Artificial Intelligence and Cognitive Science (AICS'16), University College Dublin, Dublin, Ireland, 20-21 September 2016|
