Walanbaa warramildanha: The impact of authentic Aboriginal community and school engagement on teachers’ professional knowledge

The conundrum of Indigenous education in Australia is that there are multiple, highly contested and polarising narratives that vie to inform both public and policy debate about how to construct effective schooling of Aboriginal students. Two of these contested discourses, which are seen to drive much of this debate, highlight the complexity of concerns—one which is essentially aspirational in its intent but unperceptive to the realities of Aboriginal student achievement and a second data focused discourse that is managerial and evaluative in its focus to disclose policy and pedagogic failures on student outcomes. The first has posed the politically more palatable proposition that there has been a slow, sometimes faltering but inexorable improvement in Aboriginal education, while the second highlights a mounting body of qualitative data that document an overall failure by school systems to lift Aboriginal student education achievement. The author recognises the complex and historical nature of the multilayered ‘issues’ that sit at the heart of Aboriginal underachievement. He argues that one of those underpinning issues that has plagued Aboriginal education centres on the depth of the socio-cultural disconnect between Aboriginal students and their communities, and teachers. He also argues that, too often, teachers are appointed to schools with limited social, political and professional knowledge about the particular needs and aspirations of Aboriginal students such that it impacts on their capacity to establish authentic connections to students. The research on which this article is based sets out to provide an understanding of both the nature and dynamics of community and school engagement in sites with high proportions of Aboriginal students. The study aimed to investigate teachers’ capacity to develop authentic pedagogic practices that are responsive to the educational, cultural and aspirational needs of Aboriginal students. In particular, the research highlights how the relational dynamics between schools and Aboriginal people have been deeply affected by colonial histories of exclusion and systemic disadvantage, pervasive school discourses of marginalisation and in particular an ignorance about holistic needs of Aboriginal students at school and the resultant negative relational interactions between schools and Aboriginal families. This multisite ethnographic study was undertaken with Aboriginal community members, teachers and school principals in 2012 as doctoral research. It was conducted within a relational landscape characterised by an enduring socio-cultural dissonance between schools and their Aboriginal communities. The study focused on examples of authentic collaboration and purposeful interactions between Aboriginal communities and schools that were shown to support teachers in building deeper understanding that enhanced their cognisance of the wider needs of Aboriginal students. The findings in this article highlight that when authentic engagement between Aboriginal people and schools occurred, it appeared to positively impact the teachers’ professional knowledge and created a consequent interest within these communities to engage with their schools. The research further identified that in each site the Aboriginal participants articulated an interest in developing authentic school collaborations that would enhance student outcomes. These findings suggested that teachers need to honour, understand and actively reflect on community history, contexts and aspirations to develop the skills and knowledge to address the particular socio-cultural and educational needs of Aboriginal students.     

Leveling the playing field in ICT design: Transcending knowledge roles by balancing division and privileging of knowledges

Abstract

This article develops a conceptual model of users’ and designers’ knowledge roles in the information and communication technology design process. The “ideal” center at the intersection of the axes for division of knowledge work and privileging of knowledges represents a balanced distribution of knowledge work between users and designers and an avoidance of privileging either group over the other. The article then applies this model to analyses of the design process for six video games wherein the knowledges of Indigenous peoples in North America were mobilized. It concludes by discussing implications for research and design practice, particularly for broadening the participation and self-articulation of marginalized groups.     

A large-scale donor attempt to improve educational status of the poor and household income distribution: The experience of PEDC in Vietnam

In 2003, donors combined together in Vietnam to support the provision of quality primary schooling for 226 disadvantaged districts (about a third of the country). US$160 million was invested in infrastructure, materials and training across the 226 districts. The programme has been commended by donors and received good press inside Vietnam. Comparison of achievement surveys in 2001 and 2007 showed, however, that there had been a decline in performance in the targeted districts. This article explores various hypotheses as to how this could have happened; and in particular the increasing amounts spent by better-off households on their children's education.     

Spectral and graph-theoretic bounds on steady-state-probability estimation performance for an ergodic Markov chain

Motivated by the wide application of Markov-chain steady-state-probability estimation, we pursue a spectral and graph-theoretic performance analysis of a classical estimator for steady-state probabilities here. Specifically, we connect a performance measure to estimate the structure of the underlying graph defined on the Markov-chain's state transitions. To do so, (1) we present a series of upper bounds on the performance measure in terms of the subdominant eigenvalue of the state transition matrix, which is closely connected with the graph structure; (2) as an illustration of the graph-theoretic analysis, we then relate the subdominant eigenvalue to the connectivity of the graph, including for the strong-connectivity case and the weak-link case. We also apply the results to characterize estimation in Markov chains with rewards.     

Amplitude-modulated sinusoidal microchannels for observing adaptability in C. elegans locomotion

In this paper, we present a movement-based assay to observe adaptability in Caenorhabditis elegans locomotion behavior. The assay comprises a series of sinusoidal microchannels with a fixed wavelength and modulating (increasing or decreasing) amplitude. The channel width is comparable to the body diameter of the organism. Worms are allowed to enter the channel from the input port and migrate toward the output port. Within channel sections that closely match the worm's natural undulations, the worm movement is relatively quick and steady. As the channel amplitude increases or decreases along the device, the worm faces difficulty in generating the propulsive thrust, begins to slow down and eventually fails to move forward. A set of locomotion parameters (i.e., average forward velocity, number and duration of stops, range of contact angle, and cut-off region) is defined for worm locomotion in modulated sinusoidal channels and extracted from the recorded videos. The device is tested on wild-type C. elegans (N2) and two mutants (lev-8 and unc-38). We anticipate this passive, movement-based assay can be used to screen nematodes showing difference in locomotion phenotype.     

A passion for portraits: Elizabeth Cay's pastels

Elizabeth Cay (1771–1831), the grandmother of the Scottish physicist James Clerk Maxwell (1831–1879), was a talented amateur pastellist; several of her pastel portraits survive as does her set of pastels. She studied with Archibald Skirving (1749–1819), a Scottish miniature painter who later in life turned to larger-scale portraiture in pastel and served as drawing master to the Edinburgh elite. Cay's pastels are not fabricated sticks but consist of powdered pigment housed in various glass and ceramic containers and were apparently applied by stumps, still in her workbox, or brushes. The Cay color samples were identified by spectrographic analysis, polarized light microscopy, and microchemical tests which, in addition, indicated that a number of pigment mixtures present gave specific hues in keeping with earlier treatise accounts of the preparation of a pastel gamut for practical use. Elizabeth Cay's pastel workbox may be rare surviving evidence of one way, more common that we appreciate today, in which amateurs, and perhaps professionals, practiced pastel painting.
