SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill turns the data a professor already holds about a class into aggregated, privacy-preserving evidence that informs course design and weekly-lifecycle decisions, avoiding individual-student claims while enabling data-informed actions.

Core Features & Use Cases

  • Compute per-concept readiness distributions with counts, proportions, and distribution sketches to illuminate where understanding lies.
  • Identify two-tier misconceptions prevalence and heterogeneity shapes to tailor grouping, pacing, and reteach needs at the cohort level.
  • Generate a passport-ready update block (learner_profile.cohort_evidence + known_difficulties) that communicates evidence, caveats, and recommended actions to designers and instructors.

Quick Start

Design a concise ungraded diagnostic and run a cohort-profile analysis to produce a planning-ready, privacy-preserving evidence block.

FAQPage Schema
How do I aggregate cohort data to guide higher education teaching decisions?

To aggregate cohort data for teaching decisions, compute per-concept readiness distributions and identify two-tier misconception prevalence at the cohort level. This generates a passport-ready evidence block and actionable recommendations for course design and pacing without exposing individual student data.

What is the best way to analyze class diagnostic data without exposing individual student information?

Analyzing class diagnostic data without exposing individual student information requires aggregating findings into counts, proportions, and distribution sketches. This privacy-preserving approach outputs instrument-strength caveats and cohort-level evidence blocks while ensuring no individual-level data is ever written.

How do I identify cohort misconceptions to tailor reteaching strategies?

To identify cohort misconceptions for reteaching strategies, calculate the prevalence and heterogeneity shapes of two-tier misconceptions across the entire class. This aggregated diagnostic data illuminates where group-level understanding lies, allowing you to tailor grouping, pacing, and reteach needs accordingly.

Can I generate a passport-ready evidence block for course design from ungraded diagnostics?

Yes, you can generate a passport-ready evidence block from ungraded diagnostics by running a cohort-profile analysis. This produces a learner_profile.cohort_evidence block containing known difficulties, aggregated findings, and recommended actions that directly communicate evidence and caveats to course designers and instructors.

Does cohort analytics work for the design, build, and deliver phases of a course?

Cohort analytics applies to the design, build, and deliver phases for entire cohorts in higher education. It transforms existing class data into aggregated, privacy-preserving evidence that informs weekly-lifecycle decisions and course design actions throughout these phases without making individual student claims.

When should I not use cohort-level aggregation for student analytics?

You should not use cohort-level aggregation when you need to make individual student claims or track single-learner progress. This approach is strictly designed to satisfy privacy requirements by outputting aggregated findings and evidence blocks while ensuring no individual-level data is written to any output.
