I have posted many of my handouts, assignments, rubrics, etc., on Edmodo for my students. I normally give them a printed out copy but far too often many students lose it and ask me for more copies that some will lose again for a 2nd or 3rd time. Posting them on Edmodo made it easy for my students to access the material no matter when an d where they are since Edmodo is applicable to most cell phones.
I also used the calendar feature on Edmodo to remind my students of upcoming assignments. I have spoken with my co-teacher about using Edmodo to electronically upload assignments which will allow us to respond electronically with comments for students as well as no longer have to carry around so many papers with us.
