As a teacher in the Japanese public school system, I sometimes observe various classes in Japanese. Last week, during English class, the teacher explained, in Japanese, why Americans call "Native Americans" "Indians". It was very easy to follow as I already understood the concept and instead I was just trying to pick up a few new words and ways of structuring sentences.
I was thinking that since my Japanese is high enough follow history, I might be able to do the same in a foreign language class. That way I would learn two languages at once instead of just one. Has anybody tried this? I figure it might be more effective than trying to learn Japanese or Chinese with other native English speakers.
