Hi @fadthalib, I agree with your point of view and the development of your post.

I think that when the teacher conducts a class, apart from complying with their schedules, should ensure that students pay their utmost attention to the subject taught, for which I think it is an excellent option that phones rest on a link and not be a source of distraction in the classroom.

Of course, in classes where the internet is used, it should be allowed, as long as all students are focused on teaching.

Greetings.
