ChinesePod offers a fresh alternative to out of date textbooks and the inconvenient classroom instruction.
Practical Focus - Our lessons are short, focused, and practical. They offer useful language, cultural insights, humorous anecdotes, and much more.
Free Daily Podcasts – Audio lessons from expert teachers, delivered automatically to your computer, iPod or mp3 player, every day. You listen whenever you wish – at the gym, on the bus, on your lunch-break, etc.
Learning Center - The online learning center expands on the language in the lessons, helping you make the leap from listening to being able to speak. Premium features include podcast review tools like transcripts, expansion vocabulary, exercises and lesson plans, and resources like flashcards, vocabulary games, glossary and word bank.
