Read this paragraph:

According to London School of Economics, kids get better test scores when devices are banned from school. Researchers Richard Murphy and Louis-Philippe Beland say, "We found the impact of banning phones for these students equivalent to an additional hour a week in school, or to increasing the school year by five days.” The schools' test scores improved by 6.4%. The impact on underachieving students was much more significant and their average test scores rose by 14%. This shows, students not having cell phones in the class room makes students pay attention, not get distracted, and get better grades.
