I thought cursive might help with the spacing, help define where words start & end. I do think markers are easiest to write with on paper. Handwriting Without Tears cursive has improved my own handwriting. (blushes)). At least handwriting is not the most important thing in the world. <>
Nothing helped me form natural uniformly sized letters like HWT cursive. HWT recommended golf pencils for children, rather than the fat pencils the school uses. I snapped a few #2's in half and it was easier on my kid.
