TL;DR:
The results show that RL is a feasible approach to induce effective, adaptive pedagogical strategies by using a relatively small training corpus and believe that this approach can be used to develop other adaptive and personalized learning environments.

Eliminating the Gap between the High and Low Students through Meta-cognitive Strategy Instruction
In Intelligent Tutoring Systems (pp. 603–613).
TL;DR:
It is shown that an ITS teaching a domain-independent problem-solving strategy indeed closed the gap between High and Low learners, not only in the domain where it was taught (probability) but also in a second domainWhere it was not taught (physics).

2004 chapter
Implicit Versus Explicit Learning of Strategies in a Non-procedural Cognitive Skill
In Intelligent Tutoring Systems (pp. 521–530).
TL;DR:
Two physics tutoring systems are developed, Andes and Pyrenees, where Andes is a model-tracing tutor that teaches a problem solving strategy explicitly, whereas Andes uses a novel pedagogy, developed over many years of use in the field, that provides virtually no explicit strategic instruction.
