Fluid Surveys is an online tool for quickly creating surveys that offer multiple response formats.

Fluid Surveys' drag and drop interface is so easy to use that users (it could be learners) can build a survey in less than a minute.

Fluid Surveys (and other online survey programs) is useful for "dipsticking" for knowledge in an anonymous form. By having learners anonymously answering questions in a survey, practitioners can get a sense of what their students know and what may need to be retaught.

Fluid Surveys could also be a good resource for conducting an end of course feedback survey. The option of combining multiple choice responses and text responses allows learners to share as much or as little as they want.

I'm sure you can all think of many more uses. Find out more at http://fluidsurveys.com/.
