How to develop an online community for pre-service and early career teachers

This paper contributes a number of design principles for developing large-scale online communities of pre-service and early career teachers (PS&ECTs). It presents the paradigms of connected learning, networked learning and communities of practice and contrasts them. It describes the potential for online communities to meet the needs of PS&ECTs and it identifies gaps that exist within certain types of existing online communities that currently support PS&ECTs. The paper proposes design principles for a new type of online community for PS&ECTs. These principles are drawn from the literature and from the preliminary outcomes of a pilot study.

Implementation of parallel tridiagonal solvers for a heterogeneous computing environment

Tridiagonal diagonally dominant linear systems arise in many scientific and engineering applications. The standard Thomas algorithm for solving such systems is inherently serial forming a bottleneck in computation. Algorithms such as cyclic reduction and SPIKE reduce a single large tridiagonal system into multiple small independent systems which can be solved in parallel. We have developed portable cyclic reduction and SPIKE algorithm OpenCL implementations with the intent to target a range of co-processors in a heterogeneous computing environment including Field Programmable Gate Arrays (FPGAs), Graphics Processing Units (GPUs) and other multi-core processors. In this paper, we evaluate these designs in the context of solver performance, resource efficiency and numerical accuracy.

NAPLAN, achievement gaps and embedding Indigenous perspectives in schooling: Disrupting the decolonial option

In 2004, the Queensland State Government rolled out the Embedding Aboriginal and Torres Strait Islander Perspectives in Schooling (EATSIPS) program. The policy was relaunched in 2009. This initiative aimed to improve Indigenous student learning outcomes, improve relationships between schools and Indigenous communities, and to develop a deeper understanding and respect for traditional and contemporary Aboriginal and Torres Strait Islander cultures amongst all students (EATSIPS 2011: 13). We are interested in the social justice possibilities of EATSIPS and its potential contribution to Reconciliation between Indigenous and non-Indigenous Australia. We are also interested in whether schooling practices informed by EAT-SIPS could reflect decolonising opportunities. This point is illustrated by the fact that, from 2009, it was mandatory for all state-school teachers to undergo professional development in EATSIPS, and all state schools underwent an EATSIPS audit of their policy, curriculum and pedagogical practices...

Ordering within moral orders to manage classroom trouble

This paper demonstrates how classroom trouble warranting teacher intervention can stem from transgressions in different layers of the complex moral order regulating classroom interactions. The paper builds from Durkheim’s treatment of schooling as the institution responsible for the inculcation of a shared moral order, Bernstein’s distinction between the instructional and regulative discourses in any pedagogic setting, and the concept of verticality in the instructional discourse to illuminate how curricular knowledge might apply across different contexts. This paper proposes a similar vertical dimension of moral gravity in the regulative discourse, such that some moral expectations apply across any context, while others are highly contextualized. This paper then applies this frame to data from classroom observations conducted in prevocational pathways for 16 years olds created under Australia’s “earning or learning till 17” policy. This paper describes the variety of moral premises teachers invoked in different teacher/class combinations, according to their level of moral gravity to display the dominant use of highly contextualized moral premises seeking institutional compliance, and minimal use of broader moral frames for these students on the brink of entry to the adult world.

Understanding the heterogeneity of entrepreneurship education: going beyond Gartner

This paper seeks to draw attention to the importance of appreciating and using ever-present diversity to achieve increased legitimacy for entrepreneurship education. As such, it aims to draw the reader into a reflective process of discovery as to why entrepreneurship education is important and how such importance can be prolonged. Design/methodology/approach - The paper revisits Gartner's 1985 conceptual framework for understanding the complexity of entrepreneurship. The paper proposes an alternative framework based on the logic of Gartner's framework to advance the understanding of entrepreneurship education. The authors discuss the dimensions of the proposed framework and explain the nature of the dialogic relations contained within. Findings - It is argued that the proposed conceptual framework provides a new way to understand ever-present heterogeneity related to the development and delivery of entrepreneurship education. Practical implications - The paper extends an invitation to the reader to audit their own involvement and proximity to entrepreneurship education. It argues that increased awareness of the value that heterogeneity plays in student learning outcomes and programme branding is directly related to the presence of heterogeneity across the dimensions of the conceptual framework. Originality/value - The paper introduces a simple yet powerlu1 means of understanding what factors contribute to the success or otherwise of developing and delivering entrepreneurship education. The simplicity of the approach suggested provides all entrepreneurship educators with the means to audit all facets of their programme.

Best practice full-stop: Anticipating the spillover effects of enterprise education

This paper considers the potential flow-on benefits that may arise from the increasing provision of enterprise education. The issue of vulnerability is proposed to be a factor associated with superior learning outcomes. Therefore, this paper aims to highlight the use of student and facilitator vulnerability to increase the capacity for learning in Higher Education. It is argued that students benefit from having to struggle to find their identity within a learning environment. That group work can assist the development of confidence through which improved learning behaviours are adopted. Also, the development of good learning practices in the domain of enterprise education have the potential to aid student learning outcomes in other areas of study. This paper provides another means of valuing the potential gains to be received from enterprise education.

Contemplating Whitehead's freedom and discipline

This paper extends the previous application of Alfred Whitehead's educational ideas to the domain of enterprise education. In doing so, a unique approach to enterprise education is illustrated that links students to their reality whilst also connecting the curriculum to contemporary entrepreneurship theory. The paper reports upon past cycles of reflective practice related to the developing hic et nunc teaching and learning framework. Two specific findings of note have emerged. First, that student' learning outcomes are enhanced through the oscillating influence of freedom and discipline. However, in the absence of either factor, sub-optimal outcomes are seen to occur. That is, an imbalance between freedom and discipline has resulted in sub-optimal outcomes from either a lack of student interest or an inability to adequately apply acquired knowledge. Where gains have been made, the most obvious process has been through consultation with students. Second, that the students also play an important role in shaping the nature of the learning environments within which they interact. Both findings are of significant importance to all academics charged with the responsibility of developing enterprise education curriculum. The main implication of the paper is that in the absence of sound pedagogical practises, it is possible that enterprise programs may develop a tendency to reinforce past practises. The processes of constructive alignment and criterion-based assessment are argued to offer avenues through which students can influence the educational process. They also provide the educator with a reflective pathway through which continual improvements are constantly possible. This paper provides other academics with a window through which to view the ongoing development of a process that has been recognised nationally for teaching excellence and influenced many fine young entrepreneurs. The paper also draws attention to a set of core educational philosophies that have transferable value to any academic setting. It is noted that the task of developing a learner-centred curriculum for enterprise education has been an entrepreneurial endeavour in itself. Many mistakes have been made and many memorable achievements have been celebrated.

Constructive alignment: A journey for new eyes

The needs of students engaged in enterprise education programs are of ever growing importance. This paper considers the pedagogical challenges that confront the designers of such-programs. It is argued that it is the designer's mindset that will most likely determine the program's outcomes. That, regardless of where such programs reside, their development should be guided by a learner-centred approach. The recently developed hic et nunc framework, provides an example of such a student-centred approach. The process through which student learning outcomes occur is argued to be essentially Darwinian in nature. Taking into account both knowledge and skills, it is also argued that assessment of desirable learning outcomes should occur in visible interaction spaces. That the failure to eliminate invisible interaction spaces from such programs is an invitation for criticism from those who favour a more traditional lecturer-centred approach to teaching and learning.

Natural convection in rectangular cavities at high Rayleigh number

Natural convection in rectangular two-dimensional cavities with differentially heated side walls is a standard problem in numerical heat transfer. Most of the existing studies has considered the low Ra laminar regime. The general thrust of the present research is to investigate higher Ra flows extending into the unsteady and turbulent regimes where the physics is not fully understood and appropriate models for turbulence are not yet established. In the present study the Boussinesq approximation is being used, but the theoretical background and some preliminary results have been obtained[1] for flows with variable properties.

A computer code for enclosed natural convection in the boundary layer regime

A computer code is developed for the numerical prediction of natural convection in rectangular two-dimensional cavities at high Rayleigh numbers. The governing equations are retained in the primitive variable form. The numerical method is based on finite differences and an ADI scheme. Convective terms may be approximated with either central or hybrid differencing for greater stability. A non-uniform grid distribution is possible for greater efficiency. The pressure is dealt with via a SIMPLE type algorithm and the use of a fast elliptic solver for the solenoidal velocity correction field significantly reduces computing times. Preliminary results indicate that the code is reasonably accurate, robust and fast compared with existing benchmarks and finite difference based codes, particularly at high Rayleigh numbers. Extension to three-dimensional problems and turbulence studies in similar geometries is readily possible and indicated.

The laminar boundary layer regime for natural convection of air in a square cavity

Numerical predictions are obtained for laminar natural convection of air in a square two dimensional cavity at high Rayleigh numbers. Proper resolution of the core reveals weak multi-cellular structure which varies in a complex manner as the effects of convection are increased. The end of the steady laminar regime is numerically estimated to occur at Ra=2.2x10^8.

Laminar and turbulent natural convection in rectangular cavities

A computer program has been developed for the prediction of buoyancy-driven laminar and turbulent flow in rectangular air-filled two-dimensional cavities with differentially heated side walls. Laminar flow predictions for a square cavity and Rayleigh numbers from Ra = 10^3 up to the onset of unsteady flow have been obtained. Accurate solutions for Ra = 5 x 10^6, 10^7, 5 x 10^7 and 10^8 are presented and an estimate for the critical Rayleigh number at which the steady laminar flow becomes unsteady is given for this geometry. Numerical predictions of turbulent flow have been obtained for RaH~0(10^9 -10^11 ) and compared with existing experimental data. A previously developed second moment closure model (Behnia et al. 1987) has been used to model the turbulence. Results indicate that a second moment closure model is capable of predicting the observed flow features.
