Can facebook support Education ?

In consequence of advancement in technology, people nowadays are utilizing social networks for variety of purposes; such as

exchanging photos, audio and video clips and other information.In this way, social networks  are mostly used for entertainment  and less beneficial purposes.

Even though I am not totally against using the social networks for these sort of entertainment stuff, but I am contemplating ways of using them in more useful ways. Especially for teachers whose responsibility in so far as education is concern is so great and important. Teachers can build a page of achievement files in facebook. There they can post mind maps, worksheets, cross-words puzzles, flash cards audio andvideo clips as well as lesson plans and many more. There are a number of sites which have software to help them create these teaching aids such as mind maps.

In connection with students, they are mostly interested in games and entertainment and fun. They usually spend long time in these activities. Instead this unnecessary waste of time,they can dedicate some of their time for educational purposes such as exchanging ideas about current lessons and assist each other to solve learning problems they may encounter. Also for students of English they can write short stories and composition about their experiences and post on the facebook page
and in so doing they may improve their writing skill.
