It is no secret - I have applied for a job working for the US Army, in RDECOM Orlando. As part of 'spinning up', I am reading roughly 1 paper/day on the subject of AI in Education hopes of starting work with an Intelligent Tutoring System (ITS) project.
As such, I'm afraid a bunch of the research papers summarized after this post will be in the AI-ED domain, although I'll try to spice things up with the occasional Neural Networks paper.
