Okay, so we all use Wikipedia. I know some people don’t think it’s particularly useful – but really it’s just as valid as any other encyclopedia. It’s a great starting place for any research, but I wouldn’t recommend using it as the only resource for your work.
I recently discovered (I think via my brother) Simple Wikipedia. Basically the same content is covered when compared to regular Wikipedia entries, but simple English is used. This means the grammar and words used are “simple”, but not necessarily the concepts.
I think this would make using “the Internet” as a resource for learning and teaching a lot more achievable for younger students and their teachers, for students with learning difficulties and disabilities, and even for the rest of us.
