Student Success
For 2026-10-28, the student-success signal is how institutions keep student work and judgement visible as AI tools spread. University of Michigan faculty told the Senate Assembly that AI grading may need student consent and erodes expert evaluation (The Michigan Daily, 28 Oct). Three new preprints add detail: Stony Brook's Edhivo gave 36 graduate students near-instant formative feedback with instructor audit, but grading accuracy is unvalidated (27 Oct). A University of Sydney AI-permissive course assesses 87 students through six evidence channels and a supervised exam hurdle (26 Oct). A Vanderbilt feedback-only testing tutor kept 18 students doing their own testing with comparable quality (26 Oct). Operating takeaway (interpretation): pair AI use with process evidence, instructor audit and governance-agreed consent. Limits: no government evaluation or institutional outcome study dated 27 to 28 Oct; the research items are small preprints and the news items carry no outcome data.

AI-generated feedback and grading is getting faster, but faculty want human audit, validation and student consent before it touches student work
A Stony Brook preprint (27 Oct) reports that Edhivo produced near-instant formative quizzes and rubric-based feedback for 36 graduate students, with every result reviewed by the instructor, but AI-versus-instructor score agreement has not yet been measured, the authors warn of possible bias toward LLM-styled answers, and the time savings are informal estimates. On 28 Oct The Michigan Daily reported University of Michigan faculty at the Senate Assembly arguing that AI grading may need student consent because submissions are students' intellectual property, and that relying on AI undermines expert evaluation. Interpretation: AI feedback tools are most defensible today for low-stakes formative use, with instructor audit, published data-use terms and a governance route for consent. Limits: one builder-authored single-course pilot and one meeting report; no accuracy or learning data.
Operating questionBefore any AI-assisted grading or feedback pilot, have we validated scores against instructors, checked writing-style bias, and agreed consent or notice through faculty governance?

AI-permissive courses are shifting assessment toward evidence of the student's own process: verification work, explanation and feedback-only tutors
A University of Sydney preprint (26 Oct) describes an AI-permissive postgraduate engineering course (87 students) that assesses six evidence channels, including process, verification and explanation, with selective oral follow-up and a 30% supervised exam hurdle. A Vanderbilt preprint (26 Oct; 18 students) found a tutor that gives feedback but does not write tests kept students doing and verifying their own testing with comparable quality. Interpretation: rather than banning AI, these designs keep the student's own work visible and assessable, at the price of more staff time to review evidence. Limits: a design report without outcomes and a very small comparison.
Operating questionFor courses that allow AI, what evidence of the student's own planning, verification and explanation do we collect, and who has time to review it?

University of Michigan Senate Assembly: teaching center describes faculty shift from teaching to policing AI use, and faculty object to AI grading without student consent
At a University of Michigan Senate Assembly meeting held the Monday before publication, following the university's finalised guidelines for responsible and ethical AI use, a CRLT associate director said faculty face a deeply troubling transition from teaching and assessing students to policing and surveying their AI use. A former Senate Advisory Committee chair said faculty reliance on AI diminishes the need for specialised expertise and called it injurious to evaluating student work. A Dearborn psychology professor said grading with AI may require student consent because submitted work is students' intellectual property, and said she does not want assignments graded by AI.
Why it matters, evidence and limitations
- Why it matters
- Faculty governance is now raising consent and expertise objections to AI grading, a constraint on AI feedback and assessment tools aimed at student success.
- Evidence and measured results
- Reported statements at a faculty governance meeting.
- Limitations and uncertainty
- Opinions of individual faculty; the reporter paraphrases some statements; no information on the content of the finalised guidelines.
Preprint: Stony Brook pilot of Edhivo, a two-model LLM platform that generates and grades assessments with instructor review, reports faster feedback and positive student survey responses in one 36-student course
Edhivo uses one LLM to generate multiple-choice and open-ended assessments from instructor materials and a second to grade open responses against rubrics, with instructor review before release. In spring 2026 it ran in a Stony Brook graduate course on large language models (36 students), mainly for short formative pre- and post-quizzes around student presentations, about three per 80-minute session, which did not count toward grades. The authors estimate authoring time fell from about 30 to about 5 minutes per assessment including review, and that grading plus human audit would save about 8.3 hours for a 200-student open-ended assessment; they note these are informal single-instructor estimates. Of 30 survey respondents (83.3%), all agreed the interface was easy and that instant feedback improved their learning experience. Limitations listed include no proctoring safeguards, possible bias favouring LLM-drafted answers, STEM-only scope, and a pending comparison of AI and instructor scores.
Why it matters, evidence and limitations
- Why it matters
- AI-generated formative assessment and instant feedback are a common student-success proposition; this pilot shows workflow gains alongside unvalidated grading accuracy.
- Evidence and measured results
- Single-course pilot with timing estimates, unit-cost table and post-pilot Likert survey (30 of 36).
- Limitations and uncertainty
- Builder-authored preprint; graduate STEM cohort; formative only; survey measures perception, not learning; reliability data pending.
Preprint: University of Sydney redesigns a postgraduate software engineering course to permit AI, assessing competence through six evidence channels and a supervised exam hurdle; first deployment with 87 students
A 13-week AI-permissive postgraduate software engineering course lets students delegate substantial work to AI while keeping responsibility for planning, verification, review, integration and explanation. Assessment draws on six channels (product, process/origin, verification, explanation, reflection and individual assurance) linked by a collect, cross-check and escalate logic, with targeted oral follow-up where evidence is inconsistent. A supervised final exam worth 30% carries a hurdle of at least 30% of exam marks. By week 11 the deployment involved 87 students in 17 teams, 957 individual weekly Git repositories and 34 group repositories. Lessons: AI changes where rubric criteria carry evidential weight, channels need deliberate cross-checking, realised evidential strength may differ from design, and automation scales evidence collection more readily than interpretation. The author reports substantial human effort, concentrated in the coordinator role, and no outcome analysis.
Why it matters, evidence and limitations
- Why it matters
- Offers a concrete design for assessing competence when AI use is allowed, complementing secured-assessment approaches with process and verification evidence.
- Evidence and measured results
- Design description and deployment counts at week 11; no comparison group or marks.
- Limitations and uncertainty
- Single offering; technically favourable setting; author notes AI-assisted students may produce correlated evidence across channels and that assessed traces can become compliance-oriented.
Preprint: Vanderbilt classroom study finds a feedback-only AI tutor that does not write tests kept students doing their own testing with comparable test quality to a general AI assistant (18 students)
TestCompass gives targeted feedback on weaknesses in students' unit-test suites without generating executable tests. Eighteen students recruited mainly from a sophomore computer science course (one from a senior course) were randomly assigned to TestCompass or a general-purpose AI assistant for two Java unit-testing tasks; after one participant used only general AI, 8 TestCompass and 10 general-AI participants were analysed. General-AI users produced more tests, while TestCompass users spent more time developing and verifying tests themselves. Most test-suite quality measures were comparable, and TestCompass users reached similar requirement coverage with significantly fewer test methods in one task (p=0.012). Neither group reported short-term gains in perceived testing knowledge or confidence. The general-AI condition was not standardised because IRB rules let participants use different assistants.
Why it matters, evidence and limitations
- Why it matters
- Tests the common design choice of restricting a course AI tutor to feedback rather than answers, a lever for preserving practice while allowing AI.
- Evidence and measured results
- Small randomized comparison with behavioural logs, test-suite quality measures and pre/post surveys.
- Limitations and uncertainty
- Very small sample, extra-credit volunteers, fixed task order, heterogeneous control tools and short-term self-reports only.
