A threaded discussion, or thread, is a content item that simulates traditional classroom discussions. As with other discussion tools with which you may be familiar, it allows professors and students to post comments to a discussion topic, react to other students' comments, and respond to ideas shared by others in the course. Professors add threaded discussions to the course and determine topics for discussion within each thread. Discussions take place asynchronously, which means users can respond to a thread discussion at any time, regardless of whether other users are logged into the course at the same time or not.
Threaded discussions begin with one or more topics posted by the professor. Under a given topic, students post responses to the threaded discussion. Responses display below each topic. Responses can also be posted to other responses, creating a hierarchy of responses under a topic.
The available APIs allow you to replicate nearly all of the Threads experience from the LearningStudio User Interface in your application, including reading and writing posts. (Thread topics can only be created via the UI.)
