is it necessary to integrate social media in the classroom? How can I use forums like blogs, facebook, twitter etc. to be a better teacher?

Yes. Every child is on social media nowadays. Technology is taking the world over . Technology is being used in classrooms already today.So social media can also be used in the classroom, and I think the learners will find it interesting because not everyone wants to give their opinion in the classroom infront of everyone. There are learners who are great at writing. So I think it will be a good thing if the teacher can communicate with the learners about homework or work during the day or to give them tasks that will be done in class the next day.
