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.
