Fixed and variable-length segment vocoders for very low bitrate speech coding. Reliable and secure voice communication is an important aspect of military and defence operations. In order to reduce the possibility of interception, low power transmitters are normally used for radio communications, where the bandwidth is often very low. Military voice communication, therefore, requires the coding of speech at very low bitrates. Our research proposal aims to develop speech coders that can operate ....Fixed and variable-length segment vocoders for very low bitrate speech coding. Reliable and secure voice communication is an important aspect of military and defence operations. In order to reduce the possibility of interception, low power transmitters are normally used for radio communications, where the bandwidth is often very low. Military voice communication, therefore, requires the coding of speech at very low bitrates. Our research proposal aims to develop speech coders that can operate at lower bitrates and reproduce speech of high quality and intelligibility. This is highly beneficial to the defence forces of Australia as it will permit the use of high-grade encryption technology to improve the security of transmission.Read moreRead less
New lattice approach for digital broadband communications. A main limiting factor in supplying future broadband communications is overcoming signal dispersion in the transmission channel.

A main limiting factor in supplying future broadband communications is overcoming signal dispersion in the transmission channel. Recent preliminary collaboration by the chief investigators has uncovered a novel approach to this problem based on powerful mathematical lattice theory. The techniques have potential to significantly increase bandwidth and reliability compared to current technologies. This project will use lattice theory to propose, develop, analyse and test new data transmission techniques including joint coding, modulation and equalisation. The research will include theoretical analysis and hardware implementation. The overall aim is to dramatically improve reliability and throughput of data communication systems.Read moreRead less
Sustainable Mathematical Foundations: STEM-enriched Modelling . This longitudinal project aims to generate new knowledge on how sustainable, innovative mathematics learning can be fostered through STEM-enriched mathematical modelling across the early grades.

This longitudinal project aims to generate new knowledge on how sustainable, innovative mathematics learning can be fostered through STEM-enriched mathematical modelling across the early grades. Featuring interdisciplinary processes, including engineering and science, novel modelling sequences will prompt children to adapt their existing ways of mathematical thinking to develop conceptual innovations in solving future-oriented problems. New theoretical and empirical frameworks are expected to transform our outmoded problem experiences to ones that challenge all children to reach their mathematical potential. Professional learning, informed by international collaboration, is expected to transcend existing teacher development modes.Read moreRead less
Using mathematics to solve real world problems. This project aims to identify, apply and refine teaching approaches that help secondary students learn mathematical modelling, using mathematics to solve real world problems. The study will investigate the mathematical, cognitive, social and environmental factors that "enable" Year 10/11 students to develop mathematical representations of a real world problem. This project expects to generate theoretical and practical insights into how these enable ....Using mathematics to solve real world problems. This project aims to identify, apply and refine teaching approaches that help secondary students learn mathematical modelling, using mathematics to solve real world problems. The study will investigate the mathematical, cognitive, social and environmental factors that "enable" Year 10/11 students to develop mathematical representations of a real world problem. This project expects to generate theoretical and practical insights into how these enablers promote successful modelling, tasks that support students' development as modellers, and effective teaching approaches that promote student capability and interest in mathematics.Read moreRead less
Modelling with data: Advancing STEM in the primary curriculum. Improving the nation's skills in Science, Technology, Engineering, and Mathematics (STEM) remains a continuing concern, especially given the decline in international test results. The project aims to introduce a new approach to promoting this learning across grades 3-6 through modelling with data.

Improving the nation's skills in Science, Technology, Engineering, and Mathematics (STEM) remains a continuing concern, especially given the decline in international test results. The project aims to introduce a new approach to promoting this learning across grades 3-6 through modelling with data. With a focus on inquiry processes involving data variation and uncertainty within STEM-based contexts, the project aims to develop the important mathematical and statistical literacies needed for lifting student achievements. In advancing both theory and practice, the project aims to contribute to knowledge of primary students' capabilities for STEM problem solving and ways of enhancing implementation of the Australian Curriculum.Read moreRead less
Investigating the relationship between teacher expectations, student persistence and the learning of mathematics. There is a culture in many classrooms in which teachers are encouraged by students to pose easy tasks. The project will explore what is needed to encourage students to embrace challenges and to persist even when tasks are difficult. The outcome will be enhanced mathematics learning and improved student confidence.

Talking Maths: Bridging the gap through talk in Early Years mathematics . The study aims to address the gap in mathematical performance in Australia in relation to socioeconomic status (SES) by focusing on language and learning in mathematics. The study will design and evaluate a school-based intervention that positions language through talk as a key resource in teaching mathematics in Grades 1 and 2. Outcomes of the study will be empirical evidence of the effect of a language-based pedagogy on ....Talking Maths: Bridging the gap through talk in Early Years mathematics . The study aims to address the gap in mathematical performance in Australia in relation to socioeconomic status (SES) by focusing on language and learning in mathematics. The study will design and evaluate a school-based intervention that positions language through talk as a key resource in teaching mathematics in Grades 1 and 2. Outcomes of the study will be empirical evidence of the effect of a language-based pedagogy on young students' achievement in mathematics and further understanding of the relationship between talk and learning. These outcomes will inform policy and teacher education and have a long lasting impact on low SES students' educational and work opportunities with ultimate impact on economic and cultural prosperity.

The online future of Science and Engineering education: The essential elements of laboratory-based learning for remote-access implementation. Laboratory classes are a critical part of science and engineering degree programs, but there has been little research into what actually takes place within them.

Laboratory classes are a critical part of science and engineering degree programs, but there has been little research into what actually takes place within them. Remote laboratories, in which students control equipment via the internet, are one potential solution for accommodating rising numbers of students, but the interfaces must be developed to effectively support student learning. This project will investigate how students interact with equipment, each other, and with laboratory demonstrators in order to determine the crucial components of effective laboratory learning experiences. It will identify and characterise the interactions of students in laboratory classes, and develop mechanisms to support these interactions remotely.Read moreRead less
What makes for successful numeracy education in remote Indigenous contexts: an ethnographic case study approach. There are many successful teachers and schools who have enabled remote Indigenous learners to engage with, and learn, school mathematics. But what do they do? How do they do it? This project investigates and documents successful practices in 32 schools located in remote communities. The project includes the many aspects of teaching practice.
