mobile phones at school

hi ich muss ne hausaufgabe machen für ensglish was wr davon halten wenn handys in den schulen verbiten werden wir sollen son brief an die zeitung schreiben also.
hi,
my name is sarah and in my school are mobile phones banned.
In one hand i think its good ,then pupils can concentrate more on the subject matter and exams , because mobile phones ditrub the lesson when it rings. Or the pupils play games or sende messages at the school time. And its good for pupils who havent got a mobiole phone because they cant get debar. But on the other hand I think mobile phones are very important these days because wehn parents want to contact their children in important situations ..
also das mein text wenn ihr fehler sieht sagt bescheid und wenn ihr noch andere grümde dafür und dagegen habt okii thxx
