Relation of lecture mandatory attendance and lecture quality My university recently made a direction that lectures attendance is mandatory. Now my question is, are there any studies that compare mandatory and not mandatory lectures quality? The university is trying to increase its quality and this was its main step this year.

More description:
As lecture quality comparison I mean, when is it easier to concentrate, study, teach and learn? When lectures are mandatory, there are a lot of students that doesn't have real interest in subject and are disturbing and making noise. That influences all students, as you can't hear what professor is saying, professor is disturbed and interrupted in teaching. So are there any studies that prove this?

Is this in overall a good step of university? I believe that good professors can motivate students to come to lectures, and if lectures are empty, it's a sign of something (not necessarily bad quality of professor) and this doesn't solve it at all, or am I wrong?
In fact there are many studies undertaken in this topic. Below you may find the link to some of these papers.
