Characterisation of thin layer polymer cement mortared concrete masonry bond

Masonry bond is affected by many parameters such as the type of mortar used, the techniques of dispersion of mortar and the surface texture of the concrete blocks. Additionally it is understood from the studies on conventional masonry that the bond characteristics are also influenced by the curing methods as well as the age of the bond at the time of testing. These effects on thin layer mortared masonry employing polymer cement mortars are not well understood. Therefore, the effect of curing methods and age to the bond strength and deformation of masonry containing thin layered polymer cement mortar was investigated as part of an ongoing research program at the Queensland University of Technology. This paper presents an experimental investigation of the flexural and shear bond characteristics of the thin layer mortared concrete masonry. The parameters examined include the effects curing and ageing to the bond development over a period from 14 days to 56 days after fabrication. The results exhibit that dry cured thin layer mortared masonry exhibits higher bond strength and Young’s and shear moduli compared to the wet cured specimens.

Challenges in embedding numeracy throughout the curriculum in three Queensland secondary schools

The new Australian Curriculum and national standardised testing have placed the teaching of numeracy across the curriculum at the forefront of what Australian schools must do. However, it has been left to schools to determine how they do this. Although there is a growing body of literature giving examples of pedagogies that embed numeracy in various learning areas, there are few studies of cross-curricular numeracy from the management perspective. This paper responds to the research question: How do selected Queensland secondary schools interpret and apply the Australian Curriculum requirement to embed numeracy throughout the curriculum? A multiple case study design was used to investigate the actions of the senior managers and mathematics teachers in three large secondary schools located in outer Brisbane. The numeracy practices in the three schools were interpreted from asocial constructivist perspective. The study found that in each school key managers had differing constructions of numeracy that led to confusion in administrative practices, policy development and leadership. The lack of coordinated cross-curricular action in numeracy in all three schools points to the difficulty that arises when teachers do not share the cross-curricular vision of numeracy present in the Australian Curriculum. The managers identified teachers’ commitment, understanding, or skills in relation to numeracy as significant barriers to the successful implementation of numeracy in their school. Adoption of the Australian Curriculum expectation of embedding numeracy across the curriculum will require school managers to explicitly commit to initiatives that require persistence,time and, most importantly, money.

Leveraging the repository infrastructure to curate institutional heritage materials, learning objects and data assets

Developing and maintaining a successful institutional repository for research publications requires a considerable investment by the institution. Most of the money is spent on developing the skill-sets of existing staff or hiring new staff with the necessary skills. The return on this investment can be magnified by using this valuable infrastructure to curate collections of other materials such as learning objects, student work, conference proceedings and institutional or local community heritage materials. When Queensland University of Technology (QUT) implemented its repository for research publications (QUT ePrints) over 11 years ago, it was one of the first institutional repositories to be established in Australia. Currently, the repository holds over 29,000 open access research publications and the cumulative total number of full-text downloads for these document now exceeds 16 million. The full-text deposit rate for recently-published peer reviewed papers (currently over 74%) shows how well the repository has been embraced by QUT researchers. The success of QUT ePrints has resulted in requests to accommodate a plethora of materials which are ‘out of scope’ for this repository. QUT Library saw this as an opportunity to use its repository infrastructure (software, technical know-how and policies) to develop and implement a metadata repository for its research datasets (QUT Research Data Finder), a repository for research-related software (QUT Software Finder) and to curate a number of digital collections of institutional and local community heritage materials (QUT Digital Collections). This poster describes the repositories and digital collections curated by QUT Library and outlines the value delivered to the institution, and the wider community, by these initiatives.

Exploring links between pedagogical knowledge practices and student outcomes in STEM education for primary schools

Science, technology, engineering, and mathematics (STEM) education is an emerging initiative in Australia, particularly in primary schools. This qualitative research aimed to understand Year 4 students' involvement in an integrated STEM education unit that focused on science concepts (e.g., states of matter, testing properties of materials) and mathematics concepts (e.g., 3D shapes and metric measurements) for designing, making and testing a strong and safe medical kit to insulate medicines (ice cubes) at desirable temperatures. Data collection tools included student work samples, photographs, written responses from students and the teacher, and researcher notes. In a post-hoc analysis, a pedagogical knowledge practice framework (i.e., planning, timetabling, preparation, teaching strategies, content knowledge, problem solving, classroom management, questioning, implementation, assessment, and viewpoints) was used to explain links to student outcomes in STEM education. The study showed how pedagogical knowledge practices may be linked to student outcomes (knowledge, understanding, skill development, and values and attitudes) for a STEM education activity.

The Australian curriculum: The arts - intent and big ideas for implementation

For the first time all Australian students having an entitlement to be engaged in all five art forms in Primary school. The Australian Curriculum: The Arts is based on the principle that all young Australians are entitled to engage fully in all the major art forms and to be given a balanced and substantial foundation in the special knowledge and skills base of each. This will have enormous implication on the expectations of what can be achieved in secondary schools, in tertiary institutions and ultimately on the cultural life and heritage for Australia.

Exploring the Potential to Educate “Good Citizens” through the Australian Civics and Citizenship Curriculum.

This chapter examines the ways in which notions of ‘a good citizen’ and ‘civic virtue’ have been conceptualized in the new Civics and Citizenship Curriculum for students in Years 3 – 10 in Australia. It argues that whilst Civics and Citizenship Education (CCE) has, over time and in various ways, been recognized as a significant aspect of Australian education, only recently has attention been given to the relational and multidimensional conceptions of citizenship. Considerations of ‘morality’, ‘a good citizen’ and ‘civic virtue’ offer possibilities to engage with multidimensional notions of citizenship, which acknowledge that citizenship perspectives can be affected by personal, social, spatial and temporary situations (Cogan & Derricott, 2000). In the current statement on national goals for schooling in Australia, which informed the development of CCE, the Melbourne Declaration (MCEETYA, 2008) called for young Australians to be educated to “act with moral and ethical integrity” and be “committed to national values of democracy, equity and justice, and participate in Australia’s civic life” (MCEETYA, 2008, pp. 8–9). The chapter claims that this maximal emphasis (McLaughlin, 1992), based on active, values based and interpretive approaches to democratic citizenship which encourage debate and participation in civil society, was evident in the new Civics and Citizenship Curriculum. However, it contends that the recommendations of the recent Review of the Australian Curriculum: Final report (Australian Government, 2014a & b), will now limit CCE’s potential to deliver the sort of active and informed citizenship heralded by the Melbourne Declaration. This is because the Review advocates for a content-focused minimal (McLaughlin, 1992) emphasis on civic knowledge, with diminished attention to citizenship participation and processes. In doing so, the Review foregrounds conceptions of the ‘good citizen’ in more limited terms of responsibility, obligations and compliance with the status quo.

Approaches to curriculum development in Vietnamese higher education: A case study

This research used a case study approach to examine curriculum understandings and the processes of curriculum development at a Vietnamese university. The study proposes a participatory model for curriculum development contextualized for Vietnamese higher education. The study found that the curriculum is understood in diverse and sometimes conflicting ways by students, academics and administrative staff, and is developed in a hierarchical manner. Hence, the participatory model incorporates recommendations for effective practices of curriculum development at different levels within Vietnamese universities.

Two-way strong: A study of vertebrates using Queensland Indigenous knowledges and Montessori Linnaean materials to engage Indigenous secondary school students

The marginalisation that Indigenous secondary students experience in zoology science lessons can be attributed to a chasm they experience between their life in community and the classroom. The study found that the integration of Indigenous and Western science knowledge can provide transformative learning experiences for students which work to strengthen their sense of belonging to community and school. Using action research, the study investigated the integration of both-ways science education into students' zoology lessons. It privileged the community's cultural expertise, practices and connections with students and their families, which worked to enhance student engagement in their learning.

Engaging a multiple-track approach to building capacity for 21st Century engineering, opportunities and challenges for rapid curriculum renewal

‘Complexity’ is a term that is increasingly prevalent in conversations about building capacity for 21st Century professional engineers. Society is grappling with the urgent and challenging reality of accommodating seven billion people, meeting needs and innovating lifestyle improvements in ways that do not destroy atmospheric, biological and oceanic systems critical to life. Over the last two decades in particular, engineering educators have been active in attempting to build capacity amongst professionals to deliver ‘sustainable development’ in this rapidly changing global context. However curriculum literature clearly points to a lack of significant progress, with efforts best described as ad hoc and highly varied. Given the limited timeframes for action to curb environmental degradation proposed by scientists and intergovernmental agencies, the authors of this paper propose it is imperative that curriculum renewal towards education for sustainable development proceeds rapidly, systemically, and in a transformational manner. Within this context, the paper discusses the need to consider a multiple track approach to building capacity for 21st Century engineering, including priorities and timeframes for undergraduate and postgraduate curriculum renewal. The paper begins with a contextual discussion of the term complexity and how it relates to life in the 21st Century. The authors then present a whole of system approach for planning and implementing rapid curriculum renewal that addresses the critical roles of several generations of engineering professionals over the next three decades. The paper concludes with observations regarding engaging with this approach in the context of emerging accreditation requirements and existing curriculum renewal frameworks.

Sustainability into the engineering curriculum

Higher education institutions have made some progress towards Engineering Education for Sustainable Development (EESD). There is however a ‘time lag dilemma’ facing engineering educators, where the pace of traditional curriculum renewal may not be sufficient to keep up with potential market,regulatory and institutional shifts.

Mainstreaming EESD: Elements of rapid curriculum renewal

This keynote paper provides an overview of opportunities to rapidly renew curriculum to EESD, to meet the scale and pace of change required, in order to address the issues of our time – in time. The authors outline the key arguments of the six papers that will comprise the March 2009 special issue of the International Journal of Sustainability in Higher Education, on a proposed preliminary framework for rapid curriculum renewal to EESD. The authors invite conference delegates to provide feedback on these papers, and to consider how other concepts and methodologies presented at EESD08 might also be rapidly mainstreamed, to contribute to systemic integration of sustainability content throughout engineering education, in every engineering department.

Modelling intermittent microwave convective drying (IMCD) of food materials

This thesis develops comprehensive mathematical models for an advanced drying technology Intermittent Microwave Convective Drying (IMCD). The models provide an improved physical understanding of the heat and mass transport during the drying process, which will help to improve the quality of dried food and energy efficiency of the process, as well as will increase the ability of automation and optimization. The final model in this thesis represents the most comprehensive fundamental multiphase model for IMCD that considers 3D electromagnetics coupled with multiphase porous media transport processes. The 3D electromagnetics considers Maxwell's equation and multiphase transport model considers three different phases: solid matrix, liquid water and gas consisting water vapour and air. The multiphase transport includes pressure-driven flow, capillary diffusion, binary diffusion, and evaporation. The models developed in this thesis were validated with extensive experimental investigations.

SOTrain: A new program for training supervisors and operators in Australian sugar factories

The provision of effective training of supervisors and operators is essential if sugar factories are to operate profitably and in an environmentally sustainable and safe manner. The benefits of having supervisor and operator staff with a high level of operational skills are reduced stoppages, increased recovery, improved sugar quality, reduced damage to equipment, and reduced OH&S and environmental impacts. Training of new operators and supervisors in factories has traditionally relied on on-the-job training of the new or inexperienced staff by experienced supervisors and operators, supplemented by courses conducted by contractors such as Sugar Research Institute (SRI). However there is clearly a need for staff to be able to undertake training at any time, drawing on the content of online courses as required. An improved methodology for the training of factory supervisors and operators has been developed by QUT on behalf of a syndicate of mills. The new methodology provides ‘at factory’ learning via self-paced modules. Importantly, the training resources for each module are designed to support the training programs within sugar factories, thereby establishing a benchmark for training across the sugar industry. The modules include notes, training guides and session plans, guidelines for walkthrough tours of the stations, learning activities, resources such as videos, animations, job aids and competency assessments. The materials are available on the web for registered users in Australian Mills and many activities are best undertaken online. Apart from a few interactive online resources, the materials for each module can also be downloaded. The acronym SOTrain (Supervisor and Operator Training) has been applied to the new training program.

Flexible learning design in curriculum delivery promotes student engagement and develops metacognitive learners: An integrated review

Historically, university students have been the passive recipients of face-to-face instructor designed and led classes (Hudson, 2014; Myers et al., 2011). Technological advancement, however, has provided an opportunity for greater flexibility around educational structure; students are starting to expectmore fromtertiary education providers, specifically around the delivery and provision of education (Myers et al., 2011). For universities to meet the ever-changing needs of the student they need to consider the integration of flexible learning designs into their curricula. The consequent willingness of the faculty to rethink the design and delivery of curricula has seen a recent shift in the design and delivery of education. As universities strive to promote student engagement, active learning, and communities of enquiry, they are moving progressively towards flexible learning models, virtual interaction and student centric curricula (Heise and Himes, 2010; Hsu and Hsieh, 2011). The challenge this shift creates is how to best engage students throughout their studies in order to produce graduates with the skills necessary for societal and professional sustainability (Castle and McGuire, 2010). Despite a wealth of literature addressing this topic, there is a paucity of substantive, conclusive outcomes as to the efficacy of its full implementation and potential for producing capable learners. This integrative review therefore aims to inform curriculum delivery that is flexible, student centric and scaffolds learning. It also aims to identify whether this approach assists in the development of metacognitive learners.
