Grading and feedback
Assist feedback; don't automate high-stakes grading.
AI can help with feedback and speed up first-pass grading — but this is an area with strong, evidence-backed caveats. The durable rule: **AI may assist feedback, but a human educator must review, and AI should not autonomously determine high-stakes grades.**
Where AI helps. AI can draft feedback comments, generate rubric-based first-pass assessments, suggest areas for improvement, and help you give more feedback to more students than time would otherwise allow. Used as an assistant, it can improve feedback volume and consistency.
The evidence-based caveats — take them seriously.
- AI grading is biased and inconsistent. Research has found systematic bias — for example, inflating scores, compressing the range (over-scoring weaker work, under-scoring stronger), and sensitivity to how the prompt or rubric is framed. AI can be internally consistent (no fatigue) yet systematically wrong.
- Not for high-stakes assessment. Where fairness and validity really matter — grades that affect students' futures — AI shouldn't be the decider.
- Weak on nuance. AI struggles to assess originality, voice, creativity, and higher-order reasoning — often the things that matter most.
- The 'black box' fairness problem. Students perceive AI grading as opaque, which raises real fairness and trust concerns.
The durable rule. A human educator must review AI-assisted grades; AI may assist with feedback but should not autonomously determine high-stakes grades. And disclose to students when and how AI is involved in grading — transparency addresses the fairness/trust concern.
How to use it well. Use AI to draft feedback you then review and personalize; to give a first-pass read you verify; to help you provide more feedback than you could alone. Keep the actual grade decision — especially anything high-stakes — human and owned by you. Think 'AI-assisted feedback with a teacher in charge,' never 'AI grades my class.'
The takeaway: AI can assist feedback and speed first-pass grading — drafting comments, rubric-based reads, and improvement suggestions, helping you give more feedback to more students — but the evidence-based caveats are strong: AI grading is biased and inconsistent (inflating scores, compressing the range, prompt-sensitive — internally consistent yet systematically wrong), unsuitable for high-stakes assessment, weak on originality and higher-order reasoning, and perceived as an opaque 'black box.' The durable rule: a human educator must review AI-assisted grades, AI must not autonomously determine high-stakes grades, and you should disclose AI involvement to students. Use AI for draft feedback you review and personalize — 'AI-assisted feedback with a teacher in charge,' never 'AI grades my class.'
Decide your grading line: where might AI *assist* your feedback (drafting comments, first-pass reads you verify) versus what stays fully human (high-stakes grades, assessing originality and reasoning)? Write your rule: AI assists feedback, I review and own all grades, and I disclose AI involvement to students. Test AI on a sample — does its scoring show the biases described?
