If a junior high school principal/teacher walks into classroom, & the blackboard hasn’t been erased, should a student get up and erase it?

Question

Let’s say a teacher (who’s also the principal) walks into a classroom of 7th & 8th graders for her to start her class.  But when she gets there, she notices that the blackboard still has things written from teacher who was in that classroom earlier.  Instead of erasing it, the teacher/principal just waves her arms up and down (once) in a “This annoys me; this is unacceptable” manner.  So, a 7th grader quickly gets up and erases the blackboard.  FYI, all of the students are scared of her, as she’s yelled at the teacher them to the point of crying.  Thus, perhaps student erased the blackboard.  Should she have erased it herself?

Update:

She’s yelled at the students to the point of crying*. (Typo)

Answer 1

The one who erased it is fixing a problem that doesn't belong to him or her. Yes she should have erased it herself.

Answer 2

The one who erased it is fixing a problem that doesn't belong to him or her. Yes she should have erased it herself.

Answer 3

Well if her arms work well enough for her to flap them up and down, she is perfectly capable of erasing what is on the board. Why do some teachers assume they should be given servants? That just irritates me to death.

Answer 4

Gestures? Non-verbal communication? She has given a command. It is expected to be done. She has not specified anyone to do it. It is expected that someone will volunteer. If you are annoyed, deal with it yourself. There is nothing out of the ordinary here. It is an accepted form of communication, fast becoming irregular compared to whatever electronic forms are accepted by kids nowadays. If you are that scared of her, don't move. If nobody moves, she'll point to someone to do it. That person, bound by etiquette and classroom dynamics, must comply. If no one complies, prepare to cry!

Answer 5

Only if the kids were the ones who mucked the board up in the first place.  Nothing wrong with some brownnose or obedient one doing it for her, though.  Might even have done it because they felt badly for the teacher, saw that she was near a breaking point.  Pretty rare for a junior high kid to be compassionate, but maybe it was what happened, I do not know.

Look, being a teacher in junior high has got to be the toughest of all.  Kids that age are not very good at dealing with enforced regimentation.  They act out.  We all did it.  Nothing changes. A teacher who can't handle it, shouldn't be there.
