However, using electronic devices in schooling can bring about both advantages and disadvantages. In terms of benefits, students study better by using helpful learning apps on smartphones, laptops and other devices. Taking smartphone as an example, with diverse educational applications, students can not only access to wider range of knowledge but also learn it in a more interesting way. Moreover, electronic devices offer students abundant information resources with convenience. All information and textbooks needed for schooling can be easily stored in electronic devices which can save students time and make their backpacks lighter. Another advantage is that electronic devices can help them communicate with each other and relax by listening to music and playing games when they are bored and stressed out. In terms of drawbacks, electronic devices can distract students from their studies as they may use them to play games, text and chat in lesson time. Additionally, students have access to inappropriate information, videos and pictures. Furthermore, Students might take embarrassing pictures of others, share them on the Internet or use them to demand money or force people to do things for them. In short, although the benefits of electronic devices in classroom are undeniable, it is necessary for us to consider and set proper rules over using electronic devices at school.
