Student should not use mobile phones in class Students can not concentrate on learning if they use mobile phones in class . Firstly , They could focus on social media rather than text book.According to Matchan(2015), students prefer using digital devices for texting,tweeting and video chatting during the lecture.If students are allowed to use smart phones during the class ,they may check the feed on the social media instead of studying. Secondly ,students may be distracted by games on the mobile phones . Nowadays , there are more and more interesting games on smart phones such as Pokemon Go , Driving School and so on .However, students are too young to control themselves . In South Australia ,children spend 67% of time playing online games when they on the Internet at home.(1345.4 - SA Stats, 2010) .So we can speculate that students would also spend much time on mobile phone games if they bring smart phones to class. Thus, it is clear that students should not use mobile phones in class because they would not focus on studying if they use electronic devices.
