A teacher must possess several virtues for commanding and managing the class-group and the class-period.
One of those virtues is to be prudent and aware. Where? In what aspects?
For instance: noticing his or her students are following his or her explanations and presentations;
the relationships amongst the students – he can learn about it by organizing an excursion out;
discovering a possible bad period or while of a student;
thinking what else he or she can provide to a student who is so clever and smart and high-achieving;
reprimanding a student;
encouraging the class-group;
noticing if the students are making homework and studying;
taking the general pulse of the pace of the class; etc. / Photo from: police-academy wwwjacksonvillebeach org
