    Students' interaction data from learning environments has an inherent temporal dimension, with successive events being related through the ``next event'' relationship. Exploratory learning environments (ELEs), in particular, can generate very large volumes of such data, making their interpretation a challenging task. Using two mathematical microworlds as exemplars, we illustrate how modelling students' event-based interaction data as a graph can open up new querying and analysis opportunities. We demonstrate the possibilities that graph-based modelling can provide for querying and analysing the data, enabling investigation of student-system interactions and leading to the improvement of future versions of the ELEs under investigation.
