Social Media sites are kinda the double edged sword for educators. We have already covered using them as a personal learning tool - so I'll put that aside. Using them with students in the classroom can be a bit more of an issue. Not only is it difficult to control content when using some of the larger mass social media sites, but teachers have to be careful not to 'cross the line' with regards to their students. Having them as 'friends' on Twitter or Facebook can open up several difficulties. First of all teachers have to make sure that their own content is very professional - thats easy enough though just make a professional account and keep it clean. More difficult is making sure that your students don't inadvertantly show 'you' the teacher incriminating content. Seeing a number of your students engaging in dangerous or illegal activities will not can put you in an almost impossible situation. If you don't say anything you could be disciplined or fired depending on the circumstances, but if you 'rat' on your students you may loose their confidence and trust - not a situation you wanna be in.
