Social networks and online public forums have allowed for a 24x7 access to discussion boards customized for educational needs. Students can use Facebook, Twitter, and similar sites to talk and discuss about specific assignments or projects not only with their peers but also with the teachers. Online public forums also are there to help students.
Here's a Prezi I present to teachers with some examples of social media use in the classroom.
But you can't just leave then to it! All over the internet and forums everywhere, including this one we have people who participate and people who just read. Our students need very clear guidelines of how we expect them to interact with any pages we provide for them.
In my view, social media is something which cannot be overlooked as it provides us with a good resource on updates related to field of work which might be very relevant at times for making the kids aware. We may take input from such platforms in a way to devise some fun activities too which would help in learning process as well.
For any informative and useful resources we can use social media in classroom. But we should not encourage it too often as students might get diverted.
I have used social media discussion boards and students responded very well to them. I do have guidelines for students about participation.
