There are good reasons for this. eye hand coordenation, thinking skills to interpret, teaching grammar and logic. etc.>>. And you can walk into the philosophical society building next to independence hall. you can read the actual letters Ben Franklyn wrote to George Whitfield that started the orphan boys school which became the university of Pennsylvania. The reason they don’t teach cursive writing is to prevent students from being able to read it. if they can’t read it, they will never know real history.
I am a writer and I still jot my outlines and notes in a notebook in cursive. I love it, not only because I grew up with it, but because I think it’s an art form. I think better when I write in cursive.
