Problems with movies set in schools:
In Kindergarten Cop, Arnold Shwartzenegger has to fill in as a kindergarten teacher at the last moment for another undercover cop, Pamela Reed. The mothers of the students are shocked, shocked I tell you, that there is a male kindergarten teacher (they say this over and over to each other, as if the teacher had attennae and blue skin). The very idea that a man might teach kindergarten has obviously never occurred to any of them.
It is, of course, only the mothers discussing this, because none of the fathers are dropping their kids off at school.
I taught kindergarten and first grade for ten years. I never encountered anything close to the reaction seen in the movie. Mild surprise occasionally, but even that was rare.
Fathers drop off kids at school, too; in my experience about 1 out of every 3 to 4.
Askia is absolutely right about Daddy Day Care. Parents would be yanking their kids out of the Daddy school and putting them on the waiting list for the other shcool at light speed. But I disagree that it has anything to do with their sex, but more to do with the fact that they have no training, no experience, and are incompetent boobs, while the rival school is the kind of pre-school people apply to while their child is still in the womb, and happily pay thousands in tuition if they are lucky enough to get in.
Other general annoyances:
The teacher begins a lesson, which is interrupted a minute or two later by the dismissal bell.
Homework is routinely assigned by shouting it at the students as they leave following the dismissal bell.
That same homework/research paper is handed in as students leave class.
No matter how difficult students are described as being, they will shortly be shown sitting still and quiet, speaking one at at time, on topic.
No teacher has more than one class. That one class will be ridiculously small. It will be multicultural, regardless of where it’s located.
