I made 3 very short screencasts about 3 online tools that you could work with in the classroom. The first one is the Corpus of Contemporary American English. This is searchable database of thousands of texts which gives useful info about word frequency and collocation patterns. Watch the video here:
The second screencast is about the website GoAnimate. Here you can make cool looking text-to-video animations. Watch the screencast here.
The third online tool has been around for a while but it’s still really great and fun. Animoto allows you (and your students) to make eye-catching slideshows with audio. Watch the video here.
I hope these are useful.
