I think Chinese Learn Online is definitely one of the better programs out there. It is a gradual course which takes the learner from total beginner with no previous knowledge, and builds up from there. I used several of the podcasts for a Conversational Chinese course that I taught at our local junior college, and the response from the students was very positive. The methodology is very sound, and the real advantage is that students are not overwhelmed in the beginning, nor are they permanently stuck in a lower level.

In preparation for a trip overseas, I looked around for months trying to find a podcast/website that would help me learn Mandarin. So many were complicated to navigate or had really boring lesson plans. Some podcasts had audio that was not clear or were chanted by dull teachers. Some are just lists of vocabulary or phrases that you memorize, without context. A lot of bad teaching. I had almost given up and then found Chinese Learn Online. What a difference! The lessons are brief, memorable and logically arranged. The audio is clear and the narration friendly and very informative.
