I've been teaching for about two months now but I had my "new teacher training" just 2 days ago. I found out that I have been committing cultural faux pas galore.
(Except for one: Before I got to Vietnam, I looked up offensive gestures in this culture. Google told me not to cross my fingers, per the American "good luck" signal. Apparently this is a crude sign that refers to vaginas. I've spent some time looking at my crossed fingers, and I just don't see it, but whatever.)
What I didn't know:
1. Touching the head is a no-no. I actually found THIS on Google as well, but it seemed to be more of a thing in Thai culture and not in Vietnam. I get now why some of the little kids were not so into Duck-Duck-Goose.
2. Gesturing "come here" with one finger. Apparently this is super offensive because it is how you call over a dog? Whoops, I've been calling the three and four year olds like dogs this whole time.
3. Showing anger? Well, this should be obvious, and I haven't really been angry in my class ever. But outside of class, when Dropbox was down, when the printer didn't work, the air conditioner was out, the copier didn't work, and the office staff didn't give me either of the books for a class in 15 minutes, I was visibly fuming. Never at anyone, but still.
4. The floor is "dirty." In my 3-5 year-olds classes, we are constantly on the (carpeted) floor. We also have our shoes off. I have them crawl on the floor or even roll on the floor. And I don't care if this is a faux pas, it's really cute watching them scoot around the room, racing to touch colors. Maybe I'll just make sure they are in their seats when parents come to pick them up. The little ones don't seem to have a problem with the floor at all.
