English language has 3 versions for alphabets
The “capital” and the “small” versions are also called the print version. These are widely used. Most books and educational materials use print version.
The “cursive” is also knows as written version. Cursive writing is a more natural way of writing. The pencil flows along the paper without frequent stops within words. Also people says that Cursive is a better exercise for strengthening fine motor skills. The connecting letters help the child to produce smooth, rather than choppy, strokes with the pencil.
In terms of writing, it’s true that a cursive “b” and “d” look less like each other than their printed versions. However, current research into dyslexia and other learning disabilities show that there’s far more happening in the brain than a simple flip-flip. Children who struggle with reading and writing are experiencing a disconnect between the part of the brain that “sees” letters and the part of the brain that “identifies” letters.
