it is my notion that, mobile phones should be allowed in all kind of schools. Because there are multiple benefits of having mobile phones while in class rooms or in any kind of school some of them are here, for example you are in school and something happened with you and if you have mobile phone you may contact with your parents or other family members and inform them about your current status or you may call police or rescue agencies for help.Another reason is when you were late to reached your home whenever coming from school and your timing to reach home is out, then you may also contact with your parents via mobile and inform them that you are fine.same like that while you facing some problem with studies and want to search about particular topic then you may search on google via your smart phone and can save your valuable time.similarly when you will visit some area and you want to take some pictures and share with your friend then you may also use your cell phone for this purpose.Rather then all of above reasons the usage of mobile phone while studying in classrooms should must be conditional.for example you may just attend calls or dial calls with permission.
so in conclusion in my contention students should have allowed to mobile phones in class rooms but all cell phones should be on mute mode and usage should be conditional.
