In the closed view, a node shows only its title, its open and hide buttons, and a few statistics in the toolbar at the bottom. After reading a node, it is recommended to close it before moving to another node on the map, because keeping many nodes open can make your device perform slower.

Closing a node in 1Cademy

When a node is open, all of its parts are visible: the title, the content, and the toolbar with its action icons below the content. In this open state you can read the full node and use the toolbar's features. A closed or hidden node keeps some or all of these parts out of view until you open it again.

Opening a node in 1Cademy

By clicking on the icon shown below on the top-right corner of the node, you can hide a node on the map. Hiding a node means that the node will not be displayed on the map, and you have to click on the children list of the parent to reopen that node.

Hiding a node in 1Cademy

The 1Cademy node header contains controls for changing how a node appears on the map. These controls let you expand or collapse the node, hide the node, or hide all of its offspring.

A node is a rectangular box that represents a granular piece of knowledge, summarized in its title and explained in its content.

Nodes are connected to other nodes. Together, they make up a hierarchical Knowledge Graph.

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.
