I'm a high school chemistry teacher in China. You know, in China, English as a most important foreign language is very popular. I want to be a bilingual teacher, i.e. teaching chemistry using English. Now, I am preparing for this. but it is a very big task for me because I must to learn many vocabulary of chemistry and think in English. The worst things is that I have not meterials to study and don't know how to start my preparation. My email is dft7815@163.com. anybody can help me and give me some useful material to study. Thank you!
