Cellphones in Schools

Do you allow cellphones at your school? This question has been debated more and more lately.  On one side you have those that are for banning cellphones at school to help with bullying, social isolation, and to keep students focused on academics. The other side encourages teachers to utensil the cellphone as a resource tool for students.   But how do we balance the two?  It seems as if you can’t have one without the other.  At Southeast Polk Junior High we have a cellphone policy, in which students are not allowed to be on their phones during the school day.  We also have chromebooks for all students.  The most common issues with cellphones isn’t during classroom learning, but rather students on their phones during passing time and also at lunch.  So is this something we should consider allowing students to have access too during those times?  It is not distracting them from learning, but it does seem to cause issues with bullying and social interactions.  What does your school do?  Do you ban cellphones or do you allow it for part of the day? All day?
