The unit examines a range of issues that may influence the effectiveness of teachers and their work in Australian schools, including school climate; school systems and policies; curriculum reforms; how well schools respond to issues of equity, justice, diversity; and, the economic, social, cultural and technological changes that confront schools in Australia in the 21^st Century. In taking a broad view of the diversity and challenges confronting teachers and schools the unit examines youth culture, ethnicity, social class and gender. Against a backdrop of change, the unit also examines some traditional images of teaching and considers their appropriateness to contemporary forms and knowledge of work.
