I feel that all social media is important to use in the classroom nowadays; especially with junior high and high school age students. They are most likely going to try to sneak a peak at their devices during class anyways; might as well tell them to use their devices for an educational purpose. I think attention span overall has dwindled. Students have to feel that something is exciting in order for them to focus their attention.
Tweeting is relatively easy. It is also concise. This is extremely helpful because it gives students information in soundbites and digestible morsels. Yes, there is a negative side to this. Where is the indepth research and concentration? Are we to dummy down everything? Good questions indeed.
I feel that students enjoy games. They try to win at games. If we make education a fun game, they will work very hard to be the "winner". Of course, this does take a lot of "designing" on the part of the teacher. But, if the goal of school is truly to teach, then we must keep up with the times and teach in a way that reaches the most amount of students.
