Was this something specific to cursive?
I'm not surprised that kids would've had awful experiences, especially because this is a skill that takes time to develop, and time is often the thing in the shortest supply when it comes to teaching kids.
But you wrote your post like there was something particularly unique to the awful experiences had with learning cursive writing. I wasn't expecting that. Does it have to do with how you can 'get away' with messing handwriting in math or even in English, but when you're being graded on the appearance of cursive letters, any fine motor skills a child is struggling with gets piled on?
It can also be nice to learn as an art form! But in the same way I wouldn't expect mandatory calligraphy lessons - even though that seems like the more logical thing to introduce if we're talking about developing fine skills and learning how to read or write cursive - I don't really see the point of mandatory cursive lessons.
The option seems reasonable to have as an option. But kids are already so overworked in school, with homework and tests having increased exponentially over the last two decades, that getting to remove one thing off of their curriculum seemed like they were finally getting a break.
