1Cademy Node Visibility

A visualization of some nodes and prerequisite links between them, which is hierarchically organized and personalized for a specific 1Cademy user. The map supports four overarching learning activities: navigation, summarization, evaluation, and improvement.

1Cademy Personalized Knowledge Map View

Enables creation, evaluation, and improvement of nodes and prerequisite links on the 1Cademy shared knowledge graph.

It also supports peer review and reputation building through proposing nodes, editing nodes, and voting on node proposals.
