In the first come, first served method, participants are selected according to the date and time of registration (first come, first served). One option is to choose “provisional registration”, where the lecturer decides who is actually accepted. If necessary, you can also specify whether a waiting list should be kept from which you will automatically be placed.

Advantage: simple. There is nothing to do except specify the maximum number of participants and, if applicable, the above options when registering for the course.

Disadvantage: unfair. Students who can be online when the course is activated have an advantage. Students with a poor internet connection, with supervision tasks or students who are working at the time are at a disadvantage. Students in the first semester in particular, who may not receive their access data until much later, are clearly at a disadvantage.

Students must be given the opportunity to take all the necessary courses in a module.

Only provisional registration is possible in StudIP. A final registration is made by the teachers. The teachers ask for feedback by email after a reasonable period of time as to whether the student is actually participating. If not, the students are asked to unsubscribe.

Advantage: Legally unproblematic, as the action remains with the students.
Disadvantage: Not necessarily effective, as some students do not read their university emails.

Only provisional registration is possible in StudIP. A final registration is made by the lecturers after attending a preliminary meeting. This has the advantage that students have to attend a preliminary meeting and thus express their serious interest in the event. Students who do not attend the preliminary meeting are not finally registered by the lecturers.

Advantage: The period between the preliminary meeting and the start of the event can be chosen so that targeted preparation for the event is possible.
Disadvantage: The lecturers have to plan and hold a preliminary meeting and manage the list of participants manually. The provisional registration must be entered when registering for the course. StudIP should also definitely indicate the registration modalities in order to avoid legal problems. A corresponding text that makes the conditions of participation transparent should be provided when registering for the course.

Students cannot deregister themselves. This may create a moral hurdle to registering for the event "just like that".

Advantage: simple
Disadvantage: Not necessarily effective, as the problem may still exist. Participants cannot deregister themselves, which can also lead to more work for the teachers.
