Introducing a video clip in a lesson is always a certain way to get learners' attention. Among many others, do have a look at suggestions using video in class by David Mainwood, Jamie Keddie, Vicki Hollet and Russel Stannard (to name just a few) who have created videos and lessons around videos for both teachers and language learners.
Besides creating your own video or using the variety available on YouTube, there are also other options to choose from.
Woopid offers free videos related to hardware and software for Mac, Windows and the internet. With so many different devices used today, it's a site which may answer tech questions when working on one's own. It's easy to navigate and includes a library for users.
WatchKnow is an excellent source of educational videos, which is user-friendly to use and offers a range of subjects, from languages to mathematics.
EnglishCentral (which you can also find in my ELT/EFL resources) offers learners authentic videos, vocabulary practice as well as pronunciation practice. There's a wide range of topics to choose from (for example, Business English, Travel English, Social English, Media English) and learners can also then test their progress. Learners can also choose their level - easy, medium or hard. It's a great site to begin encouraging learners to develop their learner autonomy.
Do you have any other free video sites which you would recommend?
