When teachers and students from different cultures come into one classroom, they expect the other to behave in the way that is valued in their own culture. However, when
reality goes against the expectation, misunderstandings and cultural shocks will arise. The
unexpected feelings of the teachers toward the students, and of students toward teachers are
due to their different cultural norms underlining these behaviors. The differences in these
norms cause both teachers and students to feel the intrusion of more and more cultural
differences into their own image of self and security (Brown, 1986). Gradually they will
suffer culture stress and this will consequently lead to anger, to frustration, to helplessness and
homelessness. These misunderstandings and cultural shocks might be reduced by people of
one discourse system being conditioned to another. Learning some knowledge about other
cultures, which can affect the discourse systems, is beneficial for intercultural communication.
It is, therefore, strongly recommended that in language classrooms, culture learning is one
unavoidable part of that language.
