Student Success
For 2026-10-09, student-success evidence centers on how students use AI rather than whether they have it. A University of Eastern Finland study of 891 students' take-home exams found reflective users, who drafted first and then asked AI for feedback, earned the highest grades, while instrumental delegation could leave grades below non-users. Berkeley-led randomized trials with 1,222 online participants, presented at COLM this week, found about 10 minutes of answer-giving AI raised assisted accuracy but cut persistence and unaided accuracy once the tool was removed. Arcadia University launched an AI Navigation Hub stating every student should graduate with demonstrated AI proficiency and funding one course redesign per college for 2027-2028. Operating takeaway (interpretation): set AI tools to scaffold rather than answer, teach draft-first feedback use, and measure unaided performance. Limits: UEF is observational, Berkeley participants were not enrolled students, and Arcadia has no outcome data yet.

Patterns across the evidence
Synthesis · Lighthouse Advisory interpretation
How students use AI, not mere access, determines whether it helps or harms independent performance
UEF found reflective users who drafted first and sought AI feedback earned the highest grades while instrumental delegation could trail non-users. Berkeley-led RCTs found roughly 10 minutes of answer-giving AI reduced persistence and unaided accuracy once removed. Together they suggest campuses should steer AI defaults and instruction toward feedback and scaffolding. Limits: UEF is observational and self-disclosed; Berkeley used online adults on short tasks.
Operating questionDo our campus AI defaults and student guidance favor draft-first feedback and scaffolding, and do we measure unaided performance where AI is allowed?

Institutions are framing purposeful AI use as a taught student competency
UEF's authors recommend teaching students to use AI purposefully rather than as a substitute for their own thinking. Arcadia launched a hub stating every student should graduate with demonstrated AI proficiency, including knowing when ethical use is not possible, and funded course redesigns. Interpretation: AI literacy is moving from policy statements to curriculum and outcomes, though neither source measures a literacy intervention's effect.
Operating questionHow will we define, teach and assess AI proficiency, including when not to use AI, and which outcome will show it worked?

University of Eastern Finland: reflective AI use (write first, then ask for feedback) linked to highest take-home exam grades; instrumental use can trail non-users
UEF researchers analyzed take-home exams from 2023 and 2024 in which students could use AI if they disclosed it; 891 students took part and 159 reported AI use. They identified three approaches: instrumental (delegating the assignment and using output without substantial revision), ideational (using AI for ideas, with students often over-trusting idea quality) and reflective (producing their own content first, then asking AI for feedback or missing perspectives). Reflective users earned the highest grades compared with both other AI users and non-users, while instrumental users' grades could be lower than non-users'. The authors recommend teaching students purposeful AI use rather than treating AI as inherently good or bad.
Why it matters, evidence and limitations
- Why it matters
- Released 6 October and not yet in the archive, this gives campuses a concrete, assessable distinction between AI use that supports performance and use that undercuts it, which is directly usable in AI-literacy curricula, syllabus policies and student-success coaching.
- Evidence and measured results
- 891 students, 159 disclosed AI users; take-home exams 2023-2024; grade comparison across three coded use approaches and non-users. Effect sizes, course mix and controls are not given in the news release.
- Limitations and uncertainty
- Observational, single university, self-disclosed AI use (only 159 of 891), so selection effects are likely; data from 2023-2024 when tools and awareness were changing; release does not report effect sizes or controls; details rely on the news summary of the journal article.
UC Berkeley: randomized trials (N=1,222) find about 10 minutes of AI assistance reduces persistence and unassisted accuracy once the tool is removed
Berkeley News reports randomized trials with 1,222 online participants. In the first experiment (354 participants) one group solved fraction problems unaided while another had ChatGPT available; the AI group started more accurate, but when the tool was removed after 12 problems its accuracy dropped almost immediately and skipping rose. A second experiment (667) replicated this, and a third (201) using an SAT reading-comprehension task showed the same persistence and accuracy drop. The updated peer-reviewed paper was presented at COLM this week. Christian argues AI responses could default to being more instructive, like a tutor.
Why it matters, evidence and limitations
- Why it matters
- Published today, this is causal evidence that answer-giving AI can erode the persistence that predicts long-term learning, which is central to student-success concerns about course AI defaults, tutoring design and assessment. Relevance to HE is indirect because participants were online adults on short tasks.
- Evidence and measured results
- Three RCTs, total N=1,222 (354, 667, 201); fraction and SAT reading tasks; solve and skip rates after AI removal; peer-reviewed COLM paper. Long-term effects and campus settings were not tested.
- Limitations and uncertainty
- Online participants, not enrolled students in courses; short tasks of about 10 minutes; durability of effects unknown; news article summarizes rather than reports full statistics; a preliminary version circulated earlier in 2026.
