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.

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
Statistical Literacy for the Twenty-first Century: A Consolidated Model of Understanding for Application to Learning in Context. The overall aim of this project is to achieve a complete developmental model of school students? understanding of the concepts required to participate as statistically literate members of society.

The overall aim of this project is to achieve a complete developmental model of school students? understanding of the concepts required to participate as statistically literate members of society. Australia is now an information- and data-driven society and to achieve its goals economically, scientifically, and socially, it requires citizens who can make decisions based on appropriate quantitative understanding. A major component of this is statistical literacy. The outcomes of this project based on the theoretical model will include assessment instruments, recommendations for the school curriculum, and trialed learning materials and technologies shown to contribute to understanding, for classroom use.Read moreRead less
Automated internet warnings to prevent viewing of minor-adult sex images. Since the advent of the internet and digital cameras, the market for child exploitation material (CEM) has boomed. This project aims to explore how the visual appearance of warning messages influences internet users. It plans to conduct a randomised controlled experiment with naïve participants on a real-life website to test the effectiveness of messages designed to discourage viewers of legal ‘barely legal’ pornography.

This project aims to explore how the visual appearance of warning messages influences internet users. It plans to conduct a randomised controlled experiment with naïve participants on a real-life website to test the effectiveness of messages designed to discourage viewers of legal ‘barely legal’ pornography. It is anticipated that results will assist policing efforts by indicating whether warnings can be used to dissuade first-time CEM viewers and whether differences exist between harm or deterrent-focused messages.Read moreRead less
Cornstalks and new chums: crime and nutritional status in settler Australia. The project will use records for 200,000 Australian-born and migrant prisoners released from Tasmanian and Victorian gaols between 1853 and 1924 to probe links between childhood well-being and the propensity to re-offend. It will explore the extent to which childhood nutrition (inferred from adult height), the timing and place of birth, and adult occupation can explain migration advantages, the impact of large cities li ....Cornstalks and new chums: crime and nutritional status in settler Australia. The project will use records for 200,000 Australian-born and migrant prisoners released from Tasmanian and Victorian gaols between 1853 and 1924 to probe links between childhood well-being and the propensity to re-offend. It will explore the extent to which childhood nutrition (inferred from adult height), the timing and place of birth, and adult occupation can explain migration advantages, the impact of large cities like Melbourne on child health, and the circumstances that gave rise to recidivism? This project will also explore changes in the composition of offenders over time and the extent to which different penal systems helped offenders to ‘go straight’.Read moreRead less

This should provide significant benefits, such as effective disease management tools.Read moreRead less
Biomimetic templating radical polymerisation in nanoreactors. The aim is to develop methodology for synthesis of polymer with hitherto inaccessible control of the microstructure by free radical means, that is the molecular weight distribution and monomer sequences. This will be achieved by combining the two concepts of biomimetic templated radical polymerisation and polymerisation in nanoreactors in the form of submicron-sized micelles or droplets. Scale-up of the methodology will be developed b ....Biomimetic templating radical polymerisation in nanoreactors. The aim is to develop methodology for synthesis of polymer with hitherto inaccessible control of the microstructure by free radical means, that is the molecular weight distribution and monomer sequences. This will be achieved by combining the two concepts of biomimetic templated radical polymerisation and polymerisation in nanoreactors in the form of submicron-sized micelles or droplets. Scale-up of the methodology will be developed based on an environmentally friendly approach whereby miniemulsions are generated using carbon dioxide. Increased ability to control the polymer microstructure will enable advanced design of functional polymers with far-reaching applications in materials science, nanotechnology and nanomedicine.

The role of plant hormones in legume symbioses. Soil microbes can give plants access to previously unavailable but essential nutrients through symbioses. Legumes are unique as they form symbioses with both nitrogen-fixing bacteria and with mycorrhizal fungi that supply nutrients such as phosphate. This proposal will investigate the role of the plant hormones (small, mobile, potent growth regulators) in the formation of these symbiotic relationships across legume genera. An insight into the commo ....The role of plant hormones in legume symbioses. Soil microbes can give plants access to previously unavailable but essential nutrients through symbioses. Legumes are unique as they form symbioses with both nitrogen-fixing bacteria and with mycorrhizal fungi that supply nutrients such as phosphate. This proposal will investigate the role of the plant hormones (small, mobile, potent growth regulators) in the formation of these symbiotic relationships across legume genera. An insight into the common and divergent roles of hormones in these symbioses is essential to provide researchers and breeders with new tools to maximise nutrient acquisition by legumes, important crops contributing an estimated one billion Australian dollars per year to the Australian economy.Read moreRead less
Understanding the biological functions of the karrikin-responsive signaling system of plants in growth, development and responses to the environment. A new signalling system in plants, related to that of strigolactone hormones but evolutionarily more ancient and functionally distinct, has been discovered. It is defined by the Karrkin-Insensitive-2 (KAI2) protein discovered by its ability to confer responsiveness to karrikins from bushfires. The KAI2 system influences seed germination, and develo ....Understanding the biological functions of the karrikin-responsive signaling system of plants in growth, development and responses to the environment. A new signalling system in plants, related to that of strigolactone hormones but evolutionarily more ancient and functionally distinct, has been discovered. It is defined by the Karrkin-Insensitive-2 (KAI2) protein discovered by its ability to confer responsiveness to karrikins from bushfires. The KAI2 system influences seed germination, and development of seedlings, leaves and potentially roots. This project will use KAI2 mutants and transgenic plants to define the biological functions of KAI2 signalling, and its interactions with other signalling systems. New genes central to KAI2 signalling and responses will be identified for functional analysis. The research will reveal the significance of this new signalling system in plant biology.
