In my students' writng, they wrote "To students of English Department". I advice them to change it to "To students from English Department". Do you have any other suggestion?

Either is OK. I would prefer "of" and the article "the".

"In my students' writing..." isn't very natural English. I would use something like "In their homework, some of my students have written..." or make the simple changes I have made above.
