Cambodian schools are gradually banning students from using mobile phones in class. With international aid and economic development, Cambodia's smartphone penetration rate has exceeded 117%, and many young people, including kindergarten children, own smartphones.cell phone jammer

Similar to many Asian countries, Cambodian society generally believes that smartphones distract students and affect their learning. As a result, more and more public schools are enforcing cell phone bans. The first to take this measure was Hun Sen Krong-Tep Nimit Pailin Secondary School, followed by Hun Sen Pochentong Secondary School in Phnom Penh, Bun Rany Hun Sen Prey-Pon Secondary School in Prey Veng Province, and Ta Ork High School in Kampong Thom Province.

Oum Maly, principal of Hun Sen Pochentong Secondary School, said the school's mobile phone ban has been implemented for one year and has achieved remarkable results. Students were only allowed to use their phones for research in the library, which led to significant improvements in study discipline and time management. Students who violate the ban will have their phones confiscated and their parents or guardians must come to school in person to collect them. "After the ban was implemented, students no longer used mobile phones in class for activities unrelated to learning," Onmaly said.

According to a study by the London School of Economics, students in schools that ban mobile phone use generally perform better, especially helping lower-achieving students the most.
