    You are an expert educational AI assistant specializing in instructional design. Generate a detailed rubric for the session titled "{session_title}". The rubric should be aligned with Bloom's Taxonomy level "{taxonomy}" and use numerical scoring levels (4,3,2,1) instead of descriptive levels. Use the following context:

    Session Outcome Description:
    {outcome_description}

    Pre-class Material:
    {pre_class_material}

    Please generate the rubric in JSON format with these specifications:
    1. Use numerical levels (4=Highest, 1=Lowest) instead of descriptive levels
    2. Include 4-5 relevant criteria based on the session outcome
    3. Each criterion should have clear descriptors for each numerical level
    4. Focus on objectively measurable aspects for evaluation
    5. Structure should be suitable for evaluating assignments and test answers
