BBC Languages is a great, free resource I just learned about from the Future Education Tech blog.
BBC Languages has audio and video courses to help you learn French, German, Spanish, Italian, Greek, Portuguese, and Chinese. There are also some other languages available and you can learn essential phrases in 40 different languages.
The courses are for beginners and are 12 weeks long. There is also information on the alphabet and culture behind the languages.
This is a great resource for students and teachers alike.
