How I Use It
I require almost all types of essay writing to be completed on Edmodo. I also create quizzes for students to take via Edmodo as well. It is wonderful for me when I grade essays because I can type my annotations, and my hand no longer aches from writing so many comments on students' papers. The only problem students have is when they use googledocs to upload their essays and forget to "share" their document with me so I can open it later.
I love this site. Students receive more immediate feedback because it takes less time to grade their assignments. My only complaint is that when students send you a notification, it can show up on your phone which is great, BUT...you can't reply to their question or comment with your phone (like a text message). Instead, you have to log into Edmodo, but it would be quicker if I could just upload a reply via my phone. The other issue I had with it was at semester change. I had my students logged in per their class periods, however, their schedules change second semester, and I couldn't figure out how to change the groups they were associated with without deleting them and allowing them to join a new group which would wipe out their writing from the previous semester. But these are minor complaints. Overall, Edmodo is great!
