In this chapter we report on a project concerning the nature and use of language in classes in a Queensland Indigenous school. Language differences between Indigenous students and non-Indigenous teachers are a potential factor in the poor education outcomes of Indigenous children compared with non-Indigenous children. As part of a 3-year project based in a remote school, we have begun will be audio and video-recording Prep and Year 1 classes during lessons in which the focus is on literacy and numeracy. Relevant phases of the lessons are being transcribed in fine detail and subjected to microanalysis using Conversation Analysis. We will examine sequences in which to focus in on knowledge transmission, and focus on evidence of understanding between teachers and students, and displays of newly acquired and old knowledge. Results of the project will be used in developing teacher professional development materials.
