Design patterns approach for usage analysis in re-engineering process of learning systems

In the context of distance learning and teaching, it is important to have feedback on the learners´ usage of the learning system. The feedback is given by log files in the majority of systems. In our research activities around the re-engineering of e-learning systems driven by models, we think that it is interesting to capitalise knowledge from computer tracks by defining a structured set of design patterns. In this paper, we show that such an approach is interesting. We focus on analysing usage of learning systems more particularly analysing learner´s behavior during learning sessions to capture and define our design patterns.
