Differneces in learning behaviors

The biggest difference about the behavior between my classmates in this EBP and in the Japan is the active approach in the classroom. When I was in Japan, unless the teacher asked to and specify whom to answer his/her question, no one said anything in the class. Japanese students tend to be much afraid of making mistake in front of the classmates.
But in here in the EBP, everyone says their own opinions all the time. So there is always an active and cherrful atmosphere in the classroom. That is amazed me, and I will try more to say my openions even if it is not correct.
