Google Docs/Forms for quizzes

I love the idea of using Google Docs to have students type up reports, book answers, or whatever, but I still hae to figure out how to get around getting 200 accounts for my elementary school kids, whose parents might not want them to have email. Until then, I realized I can still use Google Forms!

Google Forms allows you to create a questionaire, survey or quiz and let your kids fill it out simply by accessing a web page. Of course, the URL is nasty but I just shortened it with TinyURL with the name of the quiz, it's much easier that way.

Sample Form (please fill out!)

After (or while) the students are filling out the forms, you can get a spreadsheet of results WITH graphs of how they answered! Check out the responses to my Sample Form.

You can make questions mandatory or optional, you can subscribe to the RSS feed for the spreadsheet, and you can sort the spreadsheet by last name (I made two seperate questions to facilitate this, "first name" and "last name", and "teacher's name" since I am in 8 different classrooms).

Finally, my favorite part - you can select a column to code for right or wrong answers. I asked it to highlight everything in red that said "no", "east" or "west" (to answer, what are magnetic poles called), and whatever else signaled a wrong answer. Or you can code green when you ask an essay question that signals a correct answer for using key vocabulary (pole, attract, iron for magnet concepts). It makes everything so easy to grade!

How does using Google Forms help you in your classes? Any questions or tips?
