Fighting the four letter words

A student swore in my class and I didn't bother to reprimand him.

I know why I made this slip. Students use foul language in a way that is completely routine. Many seem unaware of its ability to cause offense and some are surprised when called up for it; they don't think they've done anything wrong.

I can't really expect to alter the way they speak. These words are entrenched, they aren't going anywhere. All the same, I've decided to have a real crackdown on swearing. I like the idea of my classroom being an oasis of civility.

p.s. Staff probably can't get too high and mighty on bad language. Come to the staffroom for a real explosion of expletives.
