One of the biggest problems faced by classroom teachers(other than discipline problems) is cell phones. They are a constant class disruption. A lot of valuable time is wasted when you have to tell a child put the phone away or have it taken up until the end of class. They also use their phones for sexting. That is sending nude pictures of themselves to each other. This is pornography and is a crime. I know that cell phones are a necessity in the times that we live, but parents need to teach their children the right and wrong way to use their cell phones.
