Publications

Iris has been evaluated in three peer-reviewed studies. A fourth related publication examines AI tutoring in the broader context of software engineering education.

note

This paper provides broader context on AI tutoring in software engineering courses. It is not an evaluation of Iris specifically but shares research context and co-authors.
