This is my first question here, so please correct me if I'm wrong in my way of asking.
My question is suggested directly by the title. In my college institution, for each subject, half of the semester is handled by one lecture, and the next half by another one. The reasoning is that each lecturer needs to have near equal teaching responsibility. If one lecturer only is applied, there might be some lecturers who have lower or higher workloads than others.
Another reasoning is that this way we can minimize the bias that can happen with just one lecturer. If a lecturer has bias over some students but the other does not, it will somehow even out, rather than just this first lecturer handles the whole semester.
Some negative effects are there of course, such as content bias and assessment related problem, but how do you think the negative or positive effects are affecting the learning and teaching experience? My heart says the negatives are just too much.
Eventhough this has been the tradition, my math program, if possible, would like to evaluate this and possibly make changes.
