Blackboard groups are a feature in the Blackboard learning management system (LMS) that allows instructors to organize their students into smaller subgroups within a course. These groups can be used for various purposes such as collaborative projects, discussions, peer evaluations, and more. Blackboard groups provide a separate space within the course for each group to share files, hold discussions, and interact with each other. Instructors can choose to make these groups visible or hidden from other students and can also control the level of access each group has to course materials. Additionally, Blackboard groups allow instructors to easily grade and provide feedback to individual members or the entire group.
