Effective formal education or schooling is not simply a matter of teaching and learning curriculum content. It is also about values, assumptions, feelings, perceptions and relationships. No education can take place without interpersonal communication. Effective teaching can thus be qualified in terms of relating effectively in the classroom. Effective education thus also presupposes effective communication skills. Communication as the means and indeed the medium of education is therefore crucial to school success in culturally diverse education. Teachers should therefore be sensitive to the potentially problematic outcomes of intercultural communication in the culturally diverse class. Communication may be a useful source of intercultural knowledge and mutual enrichment between culturally diverse students if managed proactively by the teacher. Otherwise, it could be a source of frustration, misapprehensions, intercultural conflict and ultimately school failure. Effective and successful communication is difficult to realise even in the most favourable circumstances. Intercultural factors, therefore, create the potential for numerous communication problems and intercultural conflict. Communication, both verbal as well as non-verbal, is critically important in cross-cultural competence. As language and culture are inextricably bound, cross-cultural communication is complex and potentially problematic. In this paper, it is argued that effective educators are effective communicators and thus culturally competent in cross-cultural encounters.
