Since the late 1990s, the overall number of international students studying at tertiary level in New Zealand has increased over 400% and, although enrolments have declined recently, there are still significant numbers of overseas students. This situation has brought continuing pedagogical challenges for tertiary teachers and students. The main purposes of this case study project were to uncover what was occurring within classrooms at one New Zealand university, what types of language and instructional styles were being used by lecturers, and which aspects of degree study international students found most difficult. It was anticipated that through developing a better understanding of key factors interacting with students' emerging academic literacy, improvements to educational practices in our multicultural, multilingual program could be established.
