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
Kimberlites and Flood Basalts: Linking Primary Melts with Mantle and Crustal Sources. Intimate relationships between kimberlites and diamonds, and between flood basalts and sulphide mineralisation make the study of deep mantle-derived magmas important to the scientific and exploration communities. The proposed research therefore represents a logical scientific step forward and is hence timely and important in this internationally competitive field, and serve as a training base for young research ....Kimberlites and Flood Basalts: Linking Primary Melts with Mantle and Crustal Sources. Intimate relationships between kimberlites and diamonds, and between flood basalts and sulphide mineralisation make the study of deep mantle-derived magmas important to the scientific and exploration communities. The proposed research therefore represents a logical scientific step forward and is hence timely and important in this internationally competitive field, and serve as a training base for young researchers keen to learn the techniques and methodologies involved. The possible outcomes of the project are of wide interest to geoscientists, and may benefit the Australian economy in that they help to predict whether the continental magmas and respective rocks have formed in parts of deep mantle with mineralisation potential.Read moreRead less

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
Cracking the sulfate isotopic composition problem in ancient hydrothermal systems: application of the Carbonate-Associated Sulfate (CAS) method. Successful exploration of the deep Earth for valuable ores requires better knowledge of ore formation conditions, to feed to predictive deposit models. Our work shows great promise of improving the quality of this raw data. Smarter ore deposit prediction would likely exert its influence over the next ten years, rather than be immediate. It will increase ....Cracking the sulfate isotopic composition problem in ancient hydrothermal systems: application of the Carbonate-Associated Sulfate (CAS) method. Successful exploration of the deep Earth for valuable ores requires better knowledge of ore formation conditions, to feed to predictive deposit models. Our work shows great promise of improving the quality of this raw data. Smarter ore deposit prediction would likely exert its influence over the next ten years, rather than be immediate. It will increase exploration efficiency, saving tens of millions of dollars currently devoted to unproductive exploration. Exploration and mining are conducted primarily in regional Australia, and a healthy mining industry is therefore directly benefits hinterland communities. It also benefits all Australians through the payment of royalties and contributions to Australia's GDP from mineral exports.Read moreRead less
Submarine explosive eruptions of silicic magma: constraints on products and processes from modern sea-floor examples, ancient successions and experiments. Volcanoes are common on the sea-floor. Many have been the sites of devastating explosive eruptions throughout Earth history, producing thick layers of pumice and volcanic ash in both modern and ancient ocean basins. None of these events has been witnessed, hence, little is known about submarine explosive eruptions and the associated volcanoes. ....Submarine explosive eruptions of silicic magma: constraints on products and processes from modern sea-floor examples, ancient successions and experiments. Volcanoes are common on the sea-floor. Many have been the sites of devastating explosive eruptions throughout Earth history, producing thick layers of pumice and volcanic ash in both modern and ancient ocean basins. None of these events has been witnessed, hence, little is known about submarine explosive eruptions and the associated volcanoes. This detailed, multidisciplinary study will link exploration of modern explosive sea-floor volcanoes (western Pacific Ocean), field-work on older, submarine volcanic formations (Japan, Greece) and experiments that simulate explosive eruptions and their products. The results will elucidate sea-floor explosive volcanism and its contribution to the geology of ocean basins.Read moreRead less

Impacts of climate change on biogenic habitat-forming seaweeds in south east Australia. Seaweed-based systems on rocky reefs in south east Australia support high levels of biodiversity, endemism and economic activity (fisheries). We will provide important insight into how climate change is likely to affect the key habitat-forming seaweeds in this system, and a first assessment of how other marine species will respond to any shift in abundance of the habitat-forming seaweeds. These predictions ar ....Impacts of climate change on biogenic habitat-forming seaweeds in south east Australia. Seaweed-based systems on rocky reefs in south east Australia support high levels of biodiversity, endemism and economic activity (fisheries). We will provide important insight into how climate change is likely to affect the key habitat-forming seaweeds in this system, and a first assessment of how other marine species will respond to any shift in abundance of the habitat-forming seaweeds. These predictions are critical if human adaptation to effects of climate change are to be proactive and not reactive. We will also test a basic assumption of most bio-climate envelope models that are the basis of many current predictions of the effect of climate change on species distributions. The project will provide the basis for training of two PhD students.Read moreRead less
