Another study found that students who were not using their mobile phones during a lecture wrote down 62% more information in their notes, took more detailed notes, were able to recall more information from the lecture, and scored a full letter grade and a half higher on a multiple choice test than those students who were actively using their mobile phones.
These studies provide several compelling reasons why schools should ensure a safe and productive learning environment by adopting and enforcing policies that restrict or prohibit cell phones and wearables in classrooms.
Even the presence of a cell phone in the classroom impairs the ability of a student to learn. A study published in the journal Educational Psychology found that students who had cellphones or laptops present while a lesson was being taught scored five percent, or half a letter grade, lower on exams than students who didn't use electronics. 


Reducing cell phone use in schools is part of a responsible overall policy to protect the mental and physical health of students.
A recent study by Common Sense Media found that 97% of students use their phones during school hours, connecting to social media apps, YouTube and gaming platforms.

In another study, the majority of the students surveyed reported that instructors were largely unaware of the extent to which texting, surfing the internet or accessing social media were taking place in the classroom.
