I found a new one today. Its directed towards adults but what better way than to learn with your child.
http://oli.web.cmu.edu/openlearning/forstudents/freecoursesCarnegie Mellon has an open source for their courses. I looked at their French course and I will tell you that it includes video and audio. Plenty of opportunity for you to interact and answer questions about the video or audio. For being free, I give this site an A.
I have tried this website for me unfortunetly my internet os very slow which means that I find it hard to download programmes that require a lot of storage, most of the time the internet cuts out when the phone rings and we are still broadband. I live in outskirts of Cork and we cannot get a quicker internet apparently which is such a hassell I would love to skype video call family and friend in UK and US but it never seems to work.
Anyways going back to course I would just recoemmend using sites that offer doscunts of languages and you can go back to them time and time again. Also you and pass them onto friends to help out
a few are which I have bought are
word2word offers good courses but perhaps not so suitable for very young children. For a deal at the moment in Ireland ( im from there so its great) Id would suggest this
language course at group on I have been using this one and find it simple as it is microsoft word so am very firmiliar with it and its very easy to install into my computer, I usually have to ask my partner for help, its perfect.
