Physics MCQ Generator

A fine-tuned language model that generates high-quality physics multiple-choice questions for university entrance exam preparation with customizable cognitive skill levels based on Bloom's Taxonomy.

Model Details

Model Description

This model is specifically designed to generate competitive physics multiple-choice questions with accurate content, plausible distractors, and appropriate difficulty levels for entrance exam preparation. It supports four cognitive skill levels (Recall, Application, Analysis, Evaluation) and excels across major physics domains including mechanics, electromagnetism, thermodynamics, optics, and modern physics.

Uses

Direct Use

This model is intended for direct use in generating physics multiple-choice questions for:

• University entrance exam preparation with varying cognitive levels
• Differentiated instruction materials
• Bloom's Taxonomy-aligned assessment creation
• Educational content creation across cognitive domains
• Tutoring and teaching assistance with skill-based questioning

Downstream Use

The model can be integrated into:

• Educational platforms with adaptive learning paths
• Automated question bank generators with cognitive level filtering
• Physics tutoring applications with skill-based progression
• Exam preparation software with customized difficulty curves
• Teacher tools for creating balanced assessments

Out-of-Scope Use

• Generating questions for high-stakes exams without expert validation
• Creating medical or safety-critical content
• Replacing human physics educators entirely
• Generating content outside physics domain
• Using for psychological or cognitive assessment

Bias, Risks, and Limitations

Limitations

• Performance is best on classical physics topics; may struggle with advanced quantum mechanics
• Generated questions should always be reviewed by subject matter experts
• Limited context length (~512 tokens) may affect complex question generation
• Training data primarily from international curriculum standards
• Cognitive skill differentiation may not be perfect for all topics

Risks

• Potential for generating incorrect physics concepts if prompted unusually
• May reflect biases present in the training data
• Should not be used for high-stakes assessment without human oversight
• Cognitive level assignments may not always match intended complexity

Recommendations

Users should:

• Always verify generated questions with physics experts
• Use as a tool to assist educators, not replace them
• Disclose AI-generated content when used in educational materials
• Monitor and review outputs for accuracy and appropriateness
• Validate cognitive skill level assignments for important assessments
