Cross-cultural understanding is a field of study that looks at how people from differing cultural backgrounds communicate, in similar and different ways among themselves, and how they endeavour to communicate across cultures. In 21st century learning means be well versed when it comes to cross-cultural understanding and its aspects.

In a classroom with cultural diversity, this means being understanding to the behaviour of others who do not have his or her cultural background. In the language aspect for example, a child aware of cultural diversity must translate his or her account in a language that the all listeners can relate to. Being aware of common non-verbal interpretations is also key. This means being sensitive to what gestures or non-verbal behaviour is acceptable to both your culture and the others around you. For example, a child from bowing culture must not label a child from a non-bowing culture as impolite. Lastly, stereotyping cultures is also something to be avoided as this can lead to wrongful expectations and notions.
