Where this applies
United States, Harvard's introductory computer science course. The course staff describe deploying AI-based tools — a tutor-like assistant and code explanation — to approximately 500 on-campus students, and report that 22 out of 25 (88%) curricular answers they checked were correct. The staff are evaluating their own tools, and the paper thanks technology companies including OpenAI and Microsoft for their support.
What this means
At a large course, AI tools already answer students' questions around the clock, mostly correctly. Teaching staff move towards designing the tools and handling what they get wrong.
What it does not yet show
One course's staff evaluating their own tools with support from technology companies; not a measure of teaching elsewhere.
What you can check
Open the SIGCSE 2024 paper "Teaching CS50 with AI" and find "22 out of 25 (88%)".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
