I have encountered a lot of situations where students use the shortcut language used in text messaging when creating formal documents. Their reports and essays are sprinkled through with the use of 4 (for), 2 (to, too, two), u (You), r (are) and more. They admit that they forget that there are different types of writing each with different conventions and levels of formality. Has anyone else encountered this problem? Even more important, has anyone come up with a solution?
