I saw this on Pinterest tonight and I thought that it was 100% genius!
I know that when I try to have students read just ONE sentence out loud to hear their mistakes they always fix the blatant mistakes rather than read what is on the screen.
If you have headphones readily available, have students do this after they type up their essays.
