How I Use It
I use Edmodo to post polls, discussion questions, and short quizzes (which can be short answer or multiple choice). Edmodo also has an iPad app, which I have installed on my class iPads. A great option of incorporating Edmodo into class discussion is to have discussion prompts or even assessments posted on the site for students to complete once they've finished their class work; this is also beneficial in that 99% of students have internet access at home, so if they don't get a chance to complete the discussion/assignment in class, they can do it after school at home.
My overall opinion on Edmodo is that it is a worthwhile site and app to set up. I like how my students can create their own accounts and personalize them. My students like that Edmodo is, essentially, an "Educational Facebook" (their words). Edmodo is beneficial because it gets every student involved in discussion, and you can also have quizzes and polls that the program assess for you--that way, you spend less time slogging through piles of paperwork, and more time focusing on classroom instruction. An added benefit to Edmodo is that you can set reply restrictions so that anything a student wants to post publicly has to first be approved by you.
