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