The order in which courses are listed on the front page can be set by an administrator in Settings > Site administration > Courses > Add/edit courses.
An administrator can change the following course settings in Settings > Site administration > Appearance > Courses.
Users with the selected role(s) e.g. teachers are listed in the course description.
By default, users with the role of teacher in a course are listed in the course description for that course. If a course has several teachers, the course description can become rather long. In this case, you can create a role e.g. head of subject with no capabilities set and assign it to selected users in addition to their teacher role. If you then select only the head of subject role in the course managers setting, the course description will be shorter.
Display extended course names
By default, only course full names are displayed in the list of courses. If you check this box, then the course short name will also be displayed. Enabling this will also allow you to edit the wording using Language customization.
