Teachers have anywhere from sixty to one hundred or more students, and a teacher does not have time to run down his or her students and individually tell each student to complete his/her assignments. Now, some students may need some prodding or some reminding from time to time, but that is different. Even for students who do need prodding, a teacher does not have to verbally call these students out in class. A subtle reminder as the student enters or leaves one’s classroom is sufficient.
