On the dashboard each row of content is a "stream" (click here to read more about the dashboard). Some of these streams are automatically organised by the platform (e.g. mandatory content) and some are playlists (click here to read more about playlists).
Streams contain learning experiences. The same learning experience can appear in multiple streams. There are many types of learning experience, from simple videos to full multi-level courses built from multiple resources. Click here to read more about learning experiences.
If you create an "Undertake an online course" type of learning experience, it can contain multiple resources, user generated content, and end of level gates. Click here to read more about undertake an online course LXs.
