This unit provides a basis for an understanding about the nature and development of language. Theoretical frameworks of language will be explored with an emphasis on socio-cultural and functional approaches to language. Preservice teachers will undertake an in-depth study of the structure of language and also will focus on the interdependent relationship between context, meaning and grammar, incorporating the notion of context as culture, discourse and situation. Theories of first and additional language learning from early childhood (0–5 years) will be examined and will provide a basis for the preservice teachers’ understanding of preschool language development and the interdependence of language and emergent literacy. This unit will develop skills of communication that reflect an understanding of self and others in the learning environment, together with a respect for the richness of social and cultural diversity.
