Knowledge Graphs in Action

Interactive demo showing how structured knowledge graphs can diagnose learning gaps and guide targeted interventions.

The Question

What can knowledge graphs actually do for learning? Beyond the theoretical appeal of structured knowledge, how does it translate into something useful—like understanding why a student got an answer wrong?

What This Does

This interactive demo walks through a six-step diagnostic process:

  1. Assessment Question — A simple fraction identification problem
  2. Standard Identification — Mapping the question to learning standards
  3. Learning Components — Breaking the standard into atomic skills
  4. Gap Analysis — Identifying which components are missing based on the response
  5. Prerequisite Trace — Following the graph backward to find foundational gaps
  6. Targeted Intervention — Surfacing exactly what to teach next

The visual knowledge graph lets you explore how prerequisites, standards, and components connect—making the diagnostic reasoning visible.

What I’m Learning

Building this clarified how much structure is needed before “intelligent” diagnosis becomes possible. The graph isn’t just a nice visualization—it’s the reasoning substrate. Without explicit prerequisite relationships, you can’t trace backward from a wrong answer to its root cause.

Also: the difference between “wrong” and “why wrong” is where the real value lives.

Status

Exploratory demo. Testing whether this framing helps people understand what knowledge graphs make possible in education.
