This is a really interesting bit of food for thought about the coursebooks we work with and the kind of subliminal (or very blatant!) messages that exist in them....John Gray is a very interesting speaker, too - highly recommended!
Online screen recorder for one-click recording for free. This is a really nice free tool if you want to try out making some recordings that you can share with your learners, or getting them to make some and share them with you! Great for speaking practice homework.
