tag - Taxonomy Analytics Guidance

Role

cp4cpp.com/tag is for topic taxonomy, difficulty guidance, learning progressions, analytics, and self-study direction.

It gives the rest of CP4CPP a stable language for prerequisites, variants, pattern families, and topic relations.

Learning Style

Meta-structure learning: students learn how to learn by understanding how topics connect, branch, and build on each other.

CP4CPP Rules

• Taxonomy should use three layers by default.
• Tags must describe skill families and problem behavior, not only surface names.
• Analytics should explain what changed in a learner’s ability after solving a problem.
• tag should power navigation in doc, progression in edu, and indexing in fun.
