Whatsapp, Facebook and some other social media are intensively used by students. Particularly in under graduate level its use is more. Most challenging situation as teachers, we face,, students are using these social medias in classroom, either overtly or covertly. Even it is not possible to check, whether all students have switched off their mobile.it is difficult to ban to carry mobile in class room. Please share your view... So that, at least we can stop use social media during class lectures........... Please
