There, we observed the classes in the 1st grade and 2nd grade. Compared with Japanese elementary schools, I noticed some differences. For example, on the wall there many decoration, but off course, the decoration was about English such as number, spell, color and so on. Additionally, whereas Japanese students take classes at their personal desk, the students were taking the class at a little big table with some students.
After that, I heard that the students in the US do group work in all school including colleges and universities. This is because to develop skill for cooperating each other.
