This has led to some debate over whether students should be given this much power.There are several factors that students consider when choosing a lecturer, including the teaching style of the lecturer, the lecturers academic background, and the lecturers reputation among students. The ideal lecturer is one who has an interesting teaching style, a diverse academic background, and a good reputation among students.There are both positive and negative aspects to allowing students to choose their lecturers.
