Turning any text into a quiz with distractors that diagnose misconceptions
A quarter of teachers already use AI to develop assessments, and a third use it for worksheets. The trick that separates a good AI quiz from a lazy one: forcing the model to stay inside your actual materials and to build wrong answers around real student misconceptions, so the quiz tells you something when students miss.
You are a {{grade_subject}} teacher writing a formative assessment. Using only the material below — do not add outside facts — create a quiz. Source material: {{source_material}} Quiz spec: {{question_mix}} Requirements: - Multiple choice: 4 options each, one clearly correct. Base each distractor on a realistic student misconception, and tell me in brackets which misconception each distractor targets. - Short answer: answerable in 1-3 sentences, with a model answer and a 2-point scoring note. - Any extended response: include a 3-bullet "full credit includes" key. - Order questions from recall to application, and label each question with the skill it checks. - Reading level appropriate for {{grade_level}}. No trick questions, no "all of the above," no negatively worded stems. Then produce a second version of the same quiz — reworded questions, shuffled options, same skills — that I can use for make-ups and absent students. End with a clean answer key for both versions on its own page.
Fill in your details and the prompt updates live — then copy.
**Q3 (skill: generating equivalent fractions).** Which fraction is equivalent to 2/3? A) 4/6 — correct B) 4/5 [misconception: adds the same number to top and bottom] C) 3/2 [misconception: equivalent means flipping the fraction] D) 2/6 [misconception: multiplies only the denominator] **Q7 (short answer, skill: explaining equivalence).** Explain why 6/8 and 3/4 name the same amount. *Model answer: dividing the numerator and denominator of 6/8 by 2 gives 3/4; the pieces are bigger but there are fewer of them.* (2 points: 1 for the operation, 1 for the reasoning.)
The full workflow
- Paste in your actual notes, slides, or textbook excerpt — never let the model quiz from its own memory of the topic.
- Solve every question yourself before printing; answer-key errors are the most common failure.
- Check that distractor misconceptions match errors your students actually make, and swap ones that don't.
- Bank both versions in your drive with the answer keys separated from the student copies.
Watch out for
Models make arithmetic and fact errors at exactly the moments you stop checking. Verify every answer key line by line.
A quiz generated from the model's general knowledge instead of your materials will test things you never taught.
