I use the Google Suite (docs, videos, blogs, web tools) extensively in my classroom. My senior research unit includes having the students create a Google Doc that they share with their group members. This document is where I, too, comment on their progress and where they let their group members know where they are in the research process.
I'd like to start using Google Forms more. However, my concerns are the grading of the quiz, how to embed it into my website and retakes.
