I do not support the use of personal electronic devices in learning because I see a lot of their disadvantages.

First of all, electronic devices distract students from their studies. Many students may play games, text, chat and cheat on their smartphones or tablets. They can go on the Internet, type questions and search for answers.

Second, when students use the Internet, they have access to inappropriate information, videos and pictures. They may spend many hours reading and watching, forgetting about their projects or assignments.

Last but not least, students might take embarrassing pictures of others, share them on the web or use them to demand money or force people to do things for them.

In conclusion, personal electronic devices may bring more harm than good to students, suggest that teachers ban or limit their use in the classroom

I strongly support the use of personal electronic devices in learning because I see a lot of advantages.

First of all, they can be used for both research and study purpose. Students can use the— to download and store information and textbooks. This can help them save learning time and make their backpacks lighter.

Secondly, students can study better with modern technology because there are many useful learning applications on smartphones, laptop, tablets and other media players such as dictionary, spelling, translation, pronunciation and other apps.

Last but not least, mobile devices can help students communicate with each other or relax by listening to music and playing games when they are bored or tired of studying.

In conclusion, personal electronic devices bring more good than harm to students. I suggest: that teachers allow and encourage the use of these devices in learning both inside and outside of class.
