Prompts Guide — Assign AI

Assign AI grades Moodle assignments automatically. When a student submits work, the AI reviews the submission and returns a grade with feedback.

Your prompt controls the tone, grading style, and feedback format. It is configurable globally or per assignment.

Quick rules​

Include these in your prompt:

  • Grading style — simple (numeric only), rubric (per-criterion), or guide (per-criterion with comments)
  • Scale — maximum grade (e.g., 0–100)
  • Tone — supportive, neutral, direct, constructive, etc.
  • Feedback format — strengths, improvements, next step; or a custom structure
  • Evaluation criteria — what matters most (correctness, reasoning, clarity, examples, etc.)

If the assignment instructions are unclear, tell the AI to ask for clarification instead of guessing.

Grade a submission​

Example 1 — Simple grading, supportive tone​

Use this for straightforward grading where you want a general score plus encouraging feedback.

Prompt (assignment or global settings field)

Grade this submission.

Grading style: simple.
Scale: 0–100.
Tone: supportive and constructive.

Evaluation focus:
- correctness
- clarity
- completeness

Feedback format:
1) Strengths: 2 bullets
2) Improvements: 2 bullets
3) Next step: 1 action

Rules:
- Do not invent requirements.
- If the submission is incomplete, note it clearly.

Example 2 — Rubric grading with weighted criteria​

Use this when your assignment has a rubric configured in Moodle. The AI grades each criterion individually.

Prompt (assignment or global settings field)

Grade this submission.

Grading style: rubric.
Scale: 0–100.
Tone: neutral and teacher-like.

Criteria (with weights):
1) Meets the requirements of the prompt (30%)
2) Reasoning and justification (30%)
3) Structure and clarity (20%)
4) Evidence and examples (20%)

Feedback format:
1) 1 strength
2) 3 improvements (each with a concrete example of what to change)
3) 1 next step question for the student

Rules:
- Only grade what is actually submitted.
- If the assignment instructions are unclear, ask for clarification instead of guessing.
- Grade each criterion strictly against what it describes, not against effort.
