Automatic tutoring question generation during algorithm simulation

High user interaction is the key in the educational effectiveness of algorithm visualization (AV). This paper introduces integration of an AV system with an interaction component in order to add support for the responding level of the user engagement taxonomy. We describe the resulting AV system, which is capable of providing algorithm simulation exercises with pop-up questions that guide the student in solving the exercise. This research aims at providing a system usable in teaching as well as in validating the engagement taxonomy.
