Nowdays, many students believed that the mobile phone is something fashionable and convenient to conmunicate with family members and friends.
Some of them took mobile phone to classroom, we could often heard the ring tune in the class which is act against the class discipline.
Some of them even sending SMS in class which is wasting their precious time.
I suggest: the classroom is the place where for study, should be peaceful; students shall not use mobile phone in the classroom; students shall put all attentions on study.
Students could use moblie phone in holidays but should not influence study.
