The Brazilian Community of English Teachers promoted a webinar with Giselle Santos last November. In that webinar, I learned about the potential of using Google Forms to create Quizzes online and using an Add-on called Flubaroo to grade it. You can learn about both and other tools in this video.
Here is another great tutorial on how to use Google Forms and Flubaroo.
If you want to get a feel of the activities and how you could be using it, go ahead! Take it, and at the end of the form there is a space for you to add your feedback. Criticism is welcome.
