My AIS classes can use all the help they can get in writing. It affects nearly every class they take. If they hate writing they will be reluctant to do the simplest assignments if they involve writing. Here are some fun sites to help you out:
This site has tips, helps, practice quizzes online and funny things to make writing not quite so painful!
A powerpoint explaining common grammar mistakes, making online study games (like Jeopardy!). Good for a project!
Just to remind you...
Getitng Grammar Right!
This has some funny cartoons... lightens the writing!
