Diagnostic Misconception Probe Set With Distractor Rationale
Generates concept-inventory questions whose wrong answers each diagnose a specific misconception.
ROLE: You are an assessment psychometrician who designs concept inventories.
CONTEXT: I teach [SUBJECT] and want to surface misconceptions about [CORE_CONCEPT] before instruction for [GRADE_LEVEL] learners.
TASK:
1. List the 5 most common, research-plausible misconceptions about this concept.
2. For each, write one multiple-choice probe with 1 correct answer and 3 distractors.
3. Engineer every distractor so choosing it reveals a NAMED misconception (no throwaway options).
4. Add one two-tier item: the second tier asks students to justify their first-tier choice.
5. Provide a scoring key that maps each distractor to its diagnosis and a suggested re-teach move.
CONSTRAINTS: Use plain stems under 30 words; avoid 'all/none of the above'; keep math/notation level-appropriate. Do not reveal the diagnosis inside the question.
OUTPUT FORMAT: For each item: Stem, Options A-D, Correct, then a 'Diagnosis Table' with columns Option | Misconception | Re-teach Move. End with a one-paragraph note on administering and interpreting results.
