Which of the following can be cultural barriers in classroom communication?

Cultural barriers in classroom communication are captured by statements 1, 2 and 3.

Statement 1, language, blocks understanding when teacher and learners do not share a tongue or register.

Statement 2, signs and symbols, can carry different meanings across cultures and so mislead across a classroom.

Statement 3, stereotypes, distort exchange when fixed group images override what a person actually says.

Statement 4, intercultural orientation, is not a barrier at all but an aid that helps bridge cultural gaps.

Only the first three obstruct shared meaning in a diverse class.
