Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Lecturing and teaching
Lecturing, running seminars and helping students understand the material.

Where this applies
United States, one undergraduate physics course. In a randomised crossover design over two lessons, the median learning gains relative to the pre-test baseline were over double for students using a purpose-built AI tutor compared with an in-class active learning session; the authors note a ceiling effect in post-test scores. It is two lessons in one course; the authors declared no competing interests.
What this means
A well-designed AI tutor can deliver part of what a lecture or seminar does, at least in short trials. The lecturer's role moves towards designing and supervising that teaching.
What it does not yet show
Two lessons in one course, with a ceiling effect; not a measure of teaching across universities.
What you can check
Open the Scientific Reports article "AI tutoring outperforms in-class active learning" and find "over double".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
