  A teaching experiment was carried out in a university-level thermodynamics
course using adaptive and interactive e-learning material, created in the new
Moodle question type Stateful extending the original e-learning platform STACK.
The system collects data about the students that is used to algorithmically
classify them according to their behaviour in solving problems. It is observed
that the classification of this data predicts students' success in the other
parts of the course for a majority of students. Also, the classification is
statistically consistent with Thermodynamic Concept Survey and Maryland Physics
Expectation Survey.
