If it matters,I am an adult with dyslexia who always found cursive even harder, despite all the assurances that there was "scientific proof" that I had to find it easier than print-writing.
There is research showing that the fastest, most legible handwriters avoid cursive but don't quite print, either: they skip the harder joins (so they're joining only some of the letters) and they tend to use print-like shapes for those letters whose cursive and printed shapes disagree. This is how most adults write, if they are rapid and legible at all -- so why not work toward that? There is some more info at a site called HandwritingThatWorks dot com.
That's exactly how i write! You say that writing like that would work better for Dysgraphics, but how could you improve the quality of handwriting like that?
