I study AI in education and educational big data. Five years of front-end work before this, which is why my research tends to end up as something you can open and use rather than a flowchart.
NOW
What I am on
01Wrapping the classroom-discourse model into a tool you can hand an audio file to.
02Working through a stack of learner-modeling reviews into one searchable set of notes.
03Rebuilding this site. Third version, probably not the last.
