There are various possibilities to enable communication among users and between users and tutors.
If allow feedback is checked (course settings), the course participants can send comments to the case authors on each card. These comments will automatically be displayed in the authoring system and, depending on the author's profile settings, also sent in an e-mail. This feature can be used e.g. to enable students to indicate errors on the card or to ask the author a question. Reviewer discussion is another variation: this allows reviewers of the case to also see messages from users and colleagues and to comment on these.
Allow comments: Tutor-triggered comments can be entered by tutors in the reports section and the course manager to provide the student with feedback. This commenting feature can also be activated in the course manager. Only questions/answers flagged with the corresponding allow comments checkbox in the answer options in the authoring system can be commented on by the tutors.
Additionally, a course-based allow discussion board can be activated for a course. All course participants can read and leave comments. Also, the case authors and course tutors have access to these comments and can reply.
Case rating can be activated and shows participants when they have finished a case on the case session summary.
