Body paragraph - EXAMPLE 2
What is more, the fact that teachers spend valuable time managing phone use in class takes a severe toll on the classroom atmosphere. First of all, students are very attached to their phones. So, when the teacher asks them to put their phones away, the temptation is often too great and they will try to keep using their phones in secret. The teacher then has to tell students off, or punish them, which leads to arguments and disgruntled students and teachers alike. Secondly, if the teacher has to tell students off all the time and monitor their behaviour, they cannot focus on their main task of teaching. The working environment suffers accordingly because it is no longer a given that students and teachers are focused and working towards the same goal of learning.
