I use the Internet a lot. Even though I am not a digital native, I know all my students are so not using the Internet would somehow be like going against the way things are. I use materials from the net, I use email and Drive to communicate with my students and they send me their projects as well. We use Moodle to share files and other materials and I belong to schools online (British Council).
Problems of using the internet? When connection doesn’t work!! That happens quite often and it is a problem. We are used to depending on the internet a lot. The only way to solve that problem would be not using it...
I am sure the world of Education is going to change in the near future but I refuse to believe that teachers will be ‘expendable’. Of course English courses online, TV and traslating apps will make things easier (they are already) but they will need someone (teachers) to guide them through.
