In this article, you can find a description of how a Promote program is structured.
A program is built out of three levels, the levels consist of these parts:
Level 1 (Module -Block, Event and Milestone)
In the first level you find block, event and milestone. This level doesn't contain any other information than a title, which means that the main purpose for it is to group assignments and sessions to provide a clear structure.
Level 2 (Assignment, Session)
In the second level we have the assignments and sessions and they are the main information carriers, this is where you add all content, e.g. instructions, resources, videos, images etc.
Level 3 (Task)
In the third and last level we have Task. Here you choose completion type, how the learner is suppose to complete the assignment. You can think that it is here the action happens.
