AI Meets the Classroom: When Do Large Language Models Harm Learning?

Which beliefs it touches

• C2 Answer-giving AI in practice backs it up

  Full text (preprint): in two pre-registered lab experiments with university students learning Python, LLM access had no significant overall effect on an unaided post-test in the same session; when copy-paste made substitutive use easier, understanding per topic fell (p = .009) while topics covered rose (p = .033). Exploratory usage analyses; same-session test, not delayed. Consistent with C2's split between outsourcing and mere access.
