Handwriting is a very personal matter. It is supposed to reflect character. Different nationalities certainly have recognisable handwriting traits. Some people have easily readable writing. Some produce written work which is indecipherable, whether beautiful or messy and ugly.
Many nationalities do not use the same kind of script as English, so for students from those cultures writing in English is doubly difficult: they are fighting their expressive limitations as well as trying to work out a completely new writing system at the same time. And now that word processors are becoming more and more common, people have less motivation for good handwriting.
Teachers are not in a position to ask students to change their
handwriting style, but they can insist on neatness and legibility. Especially when students are heading towards an exam, such things are crucial. With students who are having problems with English script, special classes or group sessions may have to be arranged to help them. In these classes they can be shown many examples of certain letters, and the teacher can demonstrate the strokes necessary for making those shapes - and where the letter starts (writing from left to right is difficult for some students). They can be asked to write ‘in the air’ to give them confidence or they can be asked to imitate letters on lined paper which demonstrates the position and height of letters, e.g
* umji | pmon
