Most English schools introduced (a) ban on mobile phones during classes a long time ago and now they have conclusive proof that they were right. According to the latest study, not giving students an access to their phones translates into extra week's education in a school year. Researchers also observed that test results in such schools went up by over 6 percent.
The research was conducted at several British schools before and after bans were introduced. 'While it's true that a modern technology used in the classroom engages students and improves a performance, there are also potential obstacles, as it could lead to distractions,' the researchers say.
The findings will definitely provide powerful arguments in the ongoing debate about pupils' access to mobile phones. In the UK, staggering 90 percent of teenagers own smartphone; in the US, almost 75 percent.

Tạm dịch:
Hầu hết các trường học Anh đã áp dụng lệnh cấm điện thoại di động trong lớp học từ rất lâu rồi và giờ đây họ có bằng chứng thuyết phục cho thấy họ đã đúng. Theo nghiên cứu mới nhất, việc không cho học sinh (∅) sử dụng điện thoại sẽ giúp tăng thêm một tuần học trong một năm học. Các nhà nghiên cứu cũng quan sát thấy kết quả kiểm tra ở những trường như vậy đã tăng hơn 6 phần trăm.
Nghiên cứu được tiến hành tại một số trường học Anh trước và sau khi lệnh cấm được áp dụng. Các nhà nghiên cứu cho biết 'Mặc dù đúng là (∅) công nghệ hiện đại được sử dụng trong lớp học thu hút học sinh và cải thiện (∅) hiệu suất, nhưng cũng có những trở ngại tiềm ẩn vì nó có thể dẫn đến mất tập trung'. Những phát hiện này chắc chắn sẽ đưa ra những lập luận mạnh mẽ trong cuộc tranh luận đang diễn ra về quyền truy cập vào điện thoại di động của học sinh. Ở Anh, có tới 90 phần trăm thanh thiếu niên sở hữu điện thoại thông minh; ở Hoa Kỳ, con số này là gần 75 phần trăm.
