Flexible Method for Producing Static Visualizations of Log Data

The aim in this work was to develop a method to visualize log files produced by a pilot study of an experimental e-learning platform. The e-learning system running on a web server generated detailed descriptions of its usage that were analyzed. The log files were produced to allow the project´s researchers to study offline how the system was utilized. We used open-source software tools to create a flexible system that processed a large amount of log data into concise visual representations. The visualizations revealed a set of different interaction patterns during the pilot study and showed that each teacher had a large effect on students´ interaction with the system. Thus, the results showed that the suggested visualization method can be used to support the evaluation and training of students´ proficiency in a learning environment.
