You can find all the German videos here. I have linked to a few below. They also have separate lessons specifically concerning pronunciation, grammar, and specific phrases! They even have an RSS feed! If German isn't your thing there are lessons in Chinese, English, French, Spanish and Swahili! For the low price of nothing, how can you go wrong? Especially when compared to the price of Rosetta Stone, or even Muzzy.
The amount of resources on the site is fantastic. There is a teacher's toolkit complete with lesson plans, as well as content submitted by students (click one of the dates at the top of the page).The content of the videos is also diverse. The German videos for example cover all the cases individually. For most of the languages, the Language Resource Centre has over one-hundred videos.
Each of the short videos revolve around The Angry Family, a cast of bizarre cartoon characters. I am reluctant to admit it, but I don't think I would like these videos as much if they were not weird!
Point made? Anyways I really suggest watching a couple of these each day. Keep up the awesome work at Newcastle University!
