摘要：Web-based learning environments are raising the opportunities of autonomous learningto new levels. Exercisers play an important role within this context, because they offer guidance andfeedback to the student who needs to prepare for an exam, a course, or a diploma. We present an onlinestudy guide including an exerciser developed in our engineering school aimed at freshmen student beforethey start their degree. A pilot study that lasted one semester showed various degrees of motivationtowards using the system, as measure by continuance intention. A majority of the students briefly usedthe exerciser, while a few of them made extensive, multi-day use. Detailed logs of their usage allowed usto reconstruct the precise use of the system. We report different means to analyse these logs, from whichwe extracted four usage profiles. We describe a sequence analysis method that allows a visual analysis ofthe users activities in time. We show how this method helps to identify patterns of use for each level ofusage
