A new survey conducted in Israel revealed that more than 94 percent of students admit using their cell phones to access social media during a class.
The study conducted by the University of Haifa said that only four percent reported not using their cell phones at all during class.
It was also found that in classes with more permissive teachers, cell 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.
"Based on our findings, there is almost no moment during any class when some pupil isn't using their cell phone," it added.
According to the research, 94 percent of the pupils admitted to accessing social media or file-sharing sites such as Facebook and YouTube during class, from time to time or even more frequently.
Some 95 percent of the pupils take pictures or make recordings during class for non-study purposes, 94 percent send e-mails and text messages; 93 percent listen to music during class and 91 percent actually talk on their phones during class, the study said.
