Hi HodgeHi,
regarding content within VLE's you are right there is not a great amount at the moment aimed at specifically Primary level that has been integrated. Not wanting this to sound like an advert but at Encyclopaedia Britannica (who I work for as you might tell from my login name) we have been working with a number of VLE providers for some years. Some of them search our content across multiple resources including user generated content and allow it to be re-purposed in quite a clever way - direct into lesson creation tools. - Our content is more than just an encyclopedic research tool, - as it has a lot of multimedia, flash based learning games, interactive quizzes, videos, printable worksheets and more. - And it is linked to the Nat Curriculum.
Our primary database of content is specifically written in primary friendly language and in British English.
Forum Moderators,
Again sorry if this post sounds like a bit of an advert, - as you will see from my profile I have been a member of this forum for a while but not posted in this way before but this question did appear aimed at an area that we have been working on for some time now and might be of some use.
