Is cell phone my best friend or my enemy ?

   Cell phones have advantages and disadvantages . Are they a curse or a blessing ? We all talk about using cell phones in schools as  learning tools . We all know the bad effects of cell phones on our health. However noone can go without them.  Recent  research warns us  about using cell phones all the time and their health hazard .

  .AlthoughI cell phones are banned in our Egyptian schools, each student has one hiding or showing it and they bring them to school everyday.  So bans on cell phones are hard for schools to enforce. Most teachers are still afraid of cell phones in the classroom because they know little about how to use them as a tool for learning
I was aganist cell phones with students in clsassrooms because of their  distraction or problems of cheating . I have changed my opinion in the last three months  for some reasons. First  most students have their own cell phones ,they love them ,they can use them at anytime ,anywhere from any source at any pace . So why can't we use them as tools  for learning . We can integrate their cell phones into learning process so students get engaged more with classroom content .
*Students can  collect pictures,videos and  audio recordings on their cell phones from their daily lives as homework then send them to  the teachers' blogs or making glogs .
*Students can connect to the Internet , document current events while those events are happening,

  Our technology hardware or equipments which exist and already in our schools are out-of -date . At the same time a lot of students already have  high tech devices in their pockets . If we let our students use their cell phones at schools , we will find that schools have equipped with better devices which can  work as calculators, cameras, videocameras, books and notebooks, for example -- at no or low cost to the school.

  We have  reasons for using cell phones in our classes but the main question is how.
 Why don't we  watch these videos ?
