do you want children to get good grades? So, let them stay away from the smartphone! According to a study by the London School of economics, students' test scores increased significantly in schools that prohibited students from carrying smart phones. "We found that the effect of a cell phone ban is equivalent to a student spent an hour a week in school, or the length of each school year has increased by 5 days," said the researcher Richard Murphy (Richard Murphy) and Lewis Philip Brand (Louis-Philippe Beland).
they tracked the changes in the policy of students in 91 schools in England since 2001, covering 130 thousand students.
after Prohibiting students from taking phone calls to school, their scores increased by 6.4%. For those poor students, the impact was even more significant, and their average score increased by 14%.
"these results also show that poor students are more likely to be disturbed by mobile phones, and no matter what policy the school takes, students with excellent grades can focus on the classroom," the researchers say.
Murphy and blue also emphasized that research does not imply that mobile phones or other technology products are useless for learning. However, the temptation of short messages, games and social media to students will undoubtedly have a negative impact on academic performance.
disputes over the use of mobile phones in schools. Parents insist that they need to keep in touch with their children at any time, while teachers believe that this will interfere with teaching.
New York mayor Bill Bethhau (Bill de Blasio) canceled a 10 - year ban in March this year, which previously banned students from carrying cell phones into the campus. Now, the scale of this is determined by the schools themselves.
but Murphy and blue think that this may have a negative effect. They say that by prohibiting the use of mobile phones in schools, schools can reduce students' differences in education, which will only be further expanded after allowing mobile phones to return to school.
