Empirically Evaluating the Effectiveness of POMDP vs. MDP Towards the Pedagogical Strategies Induction
In Lecture Notes in Computer Science (pp. 327–331).
author keywords: Reinforcement Learning; POMDP; MDP; ITS
TL;DR:
An empirical study where RL-induced policies are compared against a random yet reasonable policy shows that when the contents are controlled to be equal, the MDP-based policy can improve students’ learning significantly more than the random baseline while the POMDP- based policy cannot outperform the later.

Investigation of the Influence of Hint Type on Problem Solving Behavior in a Logic Proof Tutor
In Lecture Notes in Computer Science (pp. 58–62).
author keywords: Tutoring system; Hint type; Data-driven
