I included the excellent BBC Computer Tutor in my The Best Eleven Websites For Students To Learn About Computers.
Since that time (or perhaps I just missed it the first time around), the BBC has developed an extensive collection of features on their Webwise site.
Like the Computer Tutor, there are several presentations that offer text with audio support for people who are just beginning to learn about social networks and broadband. They’re definitely accessible to English Language Learners.
There’s also an impressive impressive online course for beginners on how to use the Internet.
I’ve added the main Webwise link to The Best Eleven Websites For Students To Learn About Computers, and I’ve also put it in the Computer section on my website.
