I like to know if it is possible to give individual permissions for one student response and a marker in the discussion forum and hide from view of other students?
In Brightspace, you can manage permissions and visibility settings for discussion forums and topics to control what students and other course participants can see or do. However, the platform doesn't natively support individual permissions for single responses within a discussion topic. Typically, all posts in a discussion topic are visible to anyone who has access to that topic.
For your specific need to give permissions for one student's response and a marker in a discussion forum and hide it from the view of other students, you might consider the following workaround:
Remember, while these methods can help in creating a more private interaction space within discussions, it's essential to ensure that these settings align with your course's instructional goals and comply with your institution's policies on student privacy.
If you require further assistance or have specific questions about setting this up in Brightspace, feel free to ask!
