Improving Learning & Reducing Time: A Constrained Action-Based Reinforcement Learning Approach
Improving Learning & Reducing Time: A Constrained Action-Based Reinforcement Learning Approach. PROCEEDINGS OF THE 26TH CONFERENCE ON USER MODELING, ADAPTATION AND PERSONALIZATION (UMAP'18), pp. 43–51.
author keywords: Constrained Reinforcement Learning; POMDP; Intelligent Tutoring System
TL;DR:
This work constructs a general data-driven framework called Constrained Action-based Partially Observable Markov Decision Process (CAPOMDP) to induce effective pedagogical policies and induces two types of policies: CAPOMDPLG using learning gain as reward with the goal of improving students' learning performance, and CAPomDPTime using time as reward for reducing students' time on task.

Combining Worked Examples and Problem Solving in a Data-Driven Logic Tutor
INTELLIGENT TUTORING SYSTEMS, ITS 2016, Vol. 9684, pp. 347–353.
author keywords: Worked examples; Data-driven tutor; Problem solving
TL;DR:
The results show that worked examples benefits students early in tutoring sessions, but are comparable to hint-based systems for scaffolding domain concepts, which can decrease performance for lower-proficiency students.

Data-driven Proficiency Profiling - Proof of Concept
LAK '16 CONFERENCE PROCEEDINGS: THE SIXTH INTERNATIONAL LEARNING ANALYTICS & KNOWLEDGE CONFERENCE, pp. 324–328.
author keywords: Data-driven; Tutoring system; Student classification; Clustering
TL;DR:
This study implements the data-driven proficiency profiler (DDPP) into Deep Thought, a logic tutor where students practice constructing deductive logic proofs and shows that the DDPP did improve in performance with additional data and proved to be an effective proof of concept.

Evolution of an Intelligent Deductive Logic Tutor Using Data-Driven Elements
INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE IN EDUCATION, 27(1), 5–36.
author keywords: Deductive logic instruction; Intelligent tutoring systems; Data-driven methods
TL;DR:
This work augmented Deep Thought, an existing computer-based logic tutor, by adding data-driven methods, specifically; intelligent problem selection based on the student’s current proficiency, automatically generated on-demand hints, and determination of student problem solving strategies based on clustering previous students.
