In my opinion I think students in school should be allowed to access Facebook and it shouldnt be blocked... The reason i think this is because facebook allows you to meet new people.. Lets say for example theres a new kid in the school and she or he  doesnt know anyone or doesnt know people around the area  and they  havent gone to any school events yet so of course they dont know  anyone in other cities nearby they should be allowed to get on facebook and meet some people so their not a complete stranger or a loaner when they wanna participate in these events... Facebook can also be very educational for some people you can learn about things going on in the world and Facebook like other social media has become a perfect way of sharing all kinds of information. If it is used constructively, social media can become an enormous source of knowledge and skill transmission. Some teachers believe that facebook contributes to poor grades. The truth is that students can use facebook as a study and information gathering medium. this is one of the strongest tools that has been used by students and educators is the facebook groups. How can this be used? Well it can be used by  a group of students with a  goal or classmates form a group where they can share anything related to what brings them together. They can then use the group to post questions, discussions and links to websites that provide information relevant to the course or links to their research. I think as long as teachers can monitor the students by walking around the room and checking on them everything should be fine... And yes i am aware that some students can take advantage of this but doesnt mean it isnt useful!
