In my LCG Media for Teaching blog you'll find links and ideas with extra teaching materials. Each one is accompanied by a few suggestions of how it could be used in class. I've included a range of different media, such as short films (as a rule no longer than five minutes), talks, apps, interesting visual materials, cartoons, as well as texts. Not only will they add authenticity but will also aid motivation.
Do have a look and send me your comments and feedback; you can also let me know if there are any topics, you'd like me to cover!
