Yes, my school has used electronic devices to teach and study. In my opinion, this has lots of benefits. First, this will reduce remarkably the possibility of getting visual problems. If there is enough light, not only students but also teachers will find it comfortable during the learning and teaching process. Secondly, with modern devices, the lesson can be taught in an exciting, obvious way. Take the projector as an example, information can transform from dull words on paper to live pictures, videos and so on .All in all, thanks to the unstoppable developing of technology, people can enjoy better life day by day.
