The school district’s ban on cellphones and social media is months in the making. Whether it works remains to be determined, but here's what we do know.

Starting Tuesday, students in the Los Angeles Unified School District will be banned from using cell phones on campus. The ban is aimed at improving the educational environment by limiting the use of cell phones and social media during school hours.

The district’s board passed a resolution in June in a 5-2 vote calling for a prohibition on students’ use of cell phones and social media through the entire school day.
