Google Forms: are a great way to create surveys, quizzes, etc, but combined with Flubaroo instructors now have a quick way to grade.
Flubaroo: http://www.flubaroo.com/ is an tool that integrates with Google Forms [just add the Google App Script from the gallery in the spreadsheet drop down menu] that lets you easily perform diagnostics, grade assignments and do in-class assessments [such as dipsticking or thumbs up/down but on an individual student basis], as well as exit slip/tickets to see how well students have understood content. The tool allows the isntructor to create a report and these results can be emailed or shared out to students [with an individualized message and their score].
More information on how to use Flubaroo can be found at Google Education - which includes an archived webinar]: https://sites.google.com/site/eduonair/conference-sessions/using-google-apps-to-enhance-instruction
