This document discusses language acquisition and its importance in education. It defines language acquisition as the process of learning one's native language and additional languages. Language is important for communication, mental development, cultural understanding, and career opportunities. In 21st century education, students use language to learn about other cultures, understand media influences, and communicate cross-culturally using technology. Podcasts and recording newscasts are examples of technology applications that help students practice language skills. Previous approaches relied more on rote learning while modern approaches use engaging technology to create less anxiety and more relevant learning.
