Answer: A “channel” is a collection of content and metadata, organized into a “topic tree”. For example, the Khan Academy channel has 4 levels of nested topics:
Domain > Subject > Topic > Tutorial
(e.g. “Math” > “Arithmetic” > “Fractions” > “Comparing fractions”). A channel aligned to a specific state curriculum might instead be structured as:
Grade > Subject > Unit (e.g. “Fifth Standard” > “Math” > “Unit 5”)
A channel can consist of content from the many sources we make available (such as Khan Academy, CK-12 or TESSA, among others) and/or from your own materials (as long as they are in one of the following formats: MP4, MP3, PDF, EPUB, HTML5 apps, Markdown documents, and multiple exercise formats).
You may also choose to pull select content from the existing content channels and create a new personalized channel for your learners. The content curation server allows you to pick and choose specific content pieces and arrange them however you would like.
