Not as clear as it first seemed

I’ve also been meaning to write this post for a while 🙂
A couple of years ago it came to my attention that some of our students were being told by their elementary school teachers and junior high school teachers that they were writing English letters wrong.
After an initial reaction of annoyance (this seems to be a perennial problem with some teachers who don’t have the confidence to deviate from the one correct answer given by the textbook), I decided that it might be better to find out what the official ‘stroke order’ for the alphabet in Japan is and make sure our students know it.
I have done some quick research and there doesn’t seem to be any official stroke order. I found the following two online:

This is from Nintendo

And this is from GakuryokuUp.
As you can see, they are slightly different (lower-case w, for example). Presumably the teachers are going off whatever textbook they are using in class, and are so insecure that they won’t accept alternatives.
Which kind of takes us back to the beginning. I guess we just need to teach our students that there are different ways of writing letters, and some of their teachers in the future are going to be particular about how they are written in their class. Always do things the way your current teacher wants you to, even if they are wrong (like the ALT who told one of our students that the only correct response to ‘how are you?’ is ‘I’m fine, thank you’).
Any experiences with teaching letter-writing?
