ABSTRACT
In this paper, we propose to use clustering to improve educational process mining. We want to improve both the performance and comprehensibility of the models obtained. We have used data from 84 undergraduate students who followed an online course using Moodle 2.0. We propose to group students firstly starting from data about Moodle's usage summary and/or the students' final marks in the course. Then, we propose to use data from Moodle's logs about each cluster/group of students separately in order to be able to obtain more specific and accurate models of students' behaviour. The results show that the fitness of the specific models is greater than the general model obtained using all the data, and the comprehensibility of the models can be also improved in some cases.

Examining change in students’ self-regulated learning patterns after a formative assessment using process mining techniques
AbstractThe growing popularity of e-learning platforms, such as learning management systems, has foregrounded the role of self-regulated learning (SRL) in student success. In many e-learning environments, students typically complete learning assignments ...
Highlights- Students engage in a loosely sequenced recursive self-regulated learning cycle.
- Students actively adjust self-regulated learning patterns in response to a formative assessment.
- There are group differences in the adjustment of self-...
Data quality challenges in educational process mining: building process-oriented event logs from process-unaware online learning systems
Educational process mining utilises process-oriented event logs to enable discovery of learning practices that can be used for the learner's advantage. However, learning platforms are often process-unaware, therefore do not accurately reflect ongoing ...
An open approach for learning educational data mining
Koli Calling '13: Proceedings of the 13th Koli Calling International Conference on Computing Education ResearchThe Open Monitoring Environment (OME) allows a teacher to monitor, model and, thus, understand, the learning process based on the real data rising from an educational robotics class. The OME uses a novel educational data mining approach where teachers ...
