A new study shows that 94 percent of Israeli high school students accessed social media on their phones during class.

Researchers at the University of Haifa said that just 4 percent of students reported not using their cellphones at all during class.

The researchers also found that in classes with more permissive teachers, mobile phone use was lower than in classes where the teacher imposed strict discipline.

“The students use their mobile phones in various ways — to surf the Internet and access social media, to listen to music, take photos, play games, and send text messages and photos,” the researchers said.
