Why do some lecturers run small classes in large rooms and refuse to allow us to use the spare PCs?
The lecturer decides who stays and who goes. He/she has to anticipate the numbers who will be attending the class, book a room of appropriate size and allow some time for the students to appear. If students don’t turn up at all then it can seem unfair to those students who might be waiting to use a computer. Through our publicity we encourage teaching staff to allow students to use any free computers as long as they do not disturb the class (some lecturers wait 15 minutes to allow time for students to turn up). Of course, there are times such as online exams when this is impossible.
