The document discusses several perspectives on using computer-mediated communication (CMC) in second language classrooms. Some of the key points made include: CMC allows students to communicate without fear of making errors in front of others, but it may prevent genuine face-to-face interaction; noticing differences between cultures is important for language learning, and CMC provides opportunities for intercultural exchange; addressing surface-level cultural behaviors is not enough, deeper exploration of cultural beliefs and values is needed; gaining multiple perspectives on cultural practices is valuable for students. The document questions how CALL can facilitate gaining cultural understanding and competence.
