What You Can Do

You can generate complete exam question banks (10-50 questions) that map directly to your course learning objectives and span multiple cognitive levels using Bloom's taxonomy. Claude validates question quality, ensures appropriate difficulty progression, provides detailed answer keys with rubric scoring, and creates alternative exam versions for makeup testing or practice—transforming hours of manual assessment design into a 45-minute workflow.

Features

Learning objective mapping

Align questions directly to course outcomes with explicit cognitive level (recall, comprehension, application, analysis, evaluation, synthesis)

Bloom's taxonomy calibration

Generate questions distributed across all six cognitive levels with automatic difficulty scoring

Answer key generation

Produce detailed solution guides with step-by-step work, common misconceptions, and partial credit rubrics

Question validation

Check each question for clarity, mathematical accuracy, pedagogical soundness, and discrimination potential

Difficulty progression

Auto-sequence questions from foundational to advanced with explicit difficulty ratings (beginner, intermediate, advanced)

Alternative exam versions

Generate equivalent question sets for makeup exams, practice problems, or cumulative assessments

Concept inventory design

Create diagnostic questions that probe student understanding of core misconceptions in your discipline

Distribution analysis

Verify question counts match your intended learning objective weightings with visual breakdown

Example Output

Generated Physics Midterm Question (Application level):

A 2 kg block slides down a frictionless incline at 30° for 4 meters. Calculate: (a) the acceleration along the incline, (b) the final velocity at the bottom, (c) the time required to reach the bottom.

Answer Key & Rubric:

  • Acceleration: 4.9 m/s² (2 points for correct formula and substitution)
  • Final velocity: 6.26 m/s (2 points for kinematic equation application)
  • Time: 1.28 s (2 points for algebraic solution)
  • Common error: Using g = 10 m/s² (award 1 point if calculation is internally consistent)

Difficulty Rating: Intermediate | Cognitive Level: Application | Estimated Time: 6-8 minutes


Generated Organic Chemistry Question (Analysis level):

Given the 1H NMR spectrum showing three signals at 7.2, 5.1, and 1.9 ppm with integration ratios 5:2:3, identify the compound and explain the chemical shift pattern.

Answer Key: Compound: Allylbenzene (C6H5-CH=CH-CH3). Explanation: aromatic protons (7.2 ppm, 5H), vinyl protons (5.1 ppm, 2H), methyl group (1.9 ppm, 3H). Award partial credit for correct structure even if shift assignments are incomplete.
