Assessing writing and collaboration in learning: Methodological issues

We describe the main tasks students usually complete when working in an e- learning platform, across five mean features that have to be taken into account in research efforts (writing-based activities, individual/collective level, knowledge/ pedagogy orientation, feedback, multiple stakeholders account). Ways to analyse and assist these tasks by (semi)-automatic assessments using NLP techniques is discussed. Two services aiming to assist writing-based tasks are presented along with their first validation.
