This project examines associations between teacher-student interactions and primary students' perceptions of cultural factors of learning environments with students' attitudes towards science and their understanding of science concepts. In the tradition of classroom environment research, the study will use interviews and questionnaires to obtain students' perceptions of their primary classrooms. In-depth studies will then be made of particular classrooms with the aim of enhancing the description of primary school science teaching. The project will lead to a systematic understanding of what is happening in primary school science and a direction for teachers to implement desirable changes in their teaching.Read moreRead less
Knowledge for teaching primary mathematics: How teachers' pedagogical content knowledge develops and affects classroom practices and students' mathematics achievement. The study will investigate mathematics teaching in upper primary school, to identify the influence of teachers? mathematics-specific pedagogical knowledge, first on teaching practice and subsequently on students? learning outcomes. Case study evidence shows this influence is strong, but statistical evidence shows it is weak. This ....Knowledge for teaching primary mathematics: How teachers' pedagogical content knowledge develops and affects classroom practices and students' mathematics achievement. The study will investigate mathematics teaching in upper primary school, to identify the influence of teachers? mathematics-specific pedagogical knowledge, first on teaching practice and subsequently on students? learning outcomes. Case study evidence shows this influence is strong, but statistical evidence shows it is weak. This study aims to resolve this paradox by employing quality data that probes the heart of teaching and learning mathematics within a statistical study. The growth of knowledge and classroom practices of teachers graduating from two contrasting pre-service programs will also be tracked, to inform recommendations on the nature of discipline-specific pedagogical knowledge in teacher training.Read moreRead less
Motivations for choosing teaching as a career and development in the profession: A multicohort longitudinal study of beginning teachers. Schooling contributes significantly to the preparation of young people for citizenship so it is essential for the social infrastructure of the country that State Governments, employing authorities, teacher educators, the Federal Government and recruitment bodies better understanding the different motivational profiles of those entering teacher education now and ....Motivations for choosing teaching as a career and development in the profession: A multicohort longitudinal study of beginning teachers. Schooling contributes significantly to the preparation of young people for citizenship so it is essential for the social infrastructure of the country that State Governments, employing authorities, teacher educators, the Federal Government and recruitment bodies better understanding the different motivational profiles of those entering teacher education now and why people are not retained in the profession, suffer burnout or become disgruntled less effective teachers. It is also critical that we better understand the link between motivations, self-efficacies and the support networks and strategies needed to sustain teachers in the profession, particularly in difficult to staff regions, districts and schools.

The Benefits of Utilising Visual-Spatial Representations of Numbers . The aim of this project is to investigate how visual-spatial representations of numbers enhance practice to promote the use of retrieval-based over counting-based strategies for children learning early arithmetic. About one-third of Australian children stay reliant on counting strategies for basic arithmetic, despite these being associated with lower achievement in mathematics in later years. Expected outcomes of this project ....The Benefits of Utilising Visual-Spatial Representations of Numbers . The aim of this project is to investigate how visual-spatial representations of numbers enhance practice to promote the use of retrieval-based over counting-based strategies for children learning early arithmetic. About one-third of Australian children stay reliant on counting strategies for basic arithmetic, despite these being associated with lower achievement in mathematics in later years. Expected outcomes of this project are new understandings of how problem-answer associations can be strengthened in memory and the development of tools to promote retrieval-based strategies. Potential benefits include children who are better prepared to take on higher-level mathematics in secondary school and, subsequently, more numerate citizens. Read moreRead less
