Majority

Majority - it is very unlikely for all the students to pay attention to the teacher in the class all the time, thus it is inevitable that some students will be restless at times. As a teacher, it is more worthwhile to not let minor distractions deter your course of teaching too much where the majority of the class is still interested.

Walking around the classroom can help restless students to try to pay more attention since the teacher's presence can be felt more, rather than standing in front of the class too often. In this way, the teacher can also monitor the activities going on at the back of the class.
