Impact of context and representation on year 10 students' expression of conceptions of rate

Rate is an important, but difficult mathematical concept. More than twenty years of research, especially with calculus students, report difficulties with this concept. This paper reports on an alternative analysis, from the perspective of multiple representations and context, of interviews probing twenty Victorian Year 10 students’ conceptions of rate. This analysis shows that multiple representations of functions provide different rate-related
information for different students. Understandings of rate in one representation or context are not necessarily transferred to another representation or context.

Sacred rules, secular revelations : the conceptions of rights in pre-modern Europe

This paper is an attempt to reflect on the methodological approaches that I bring to ‘reading law’ in my current project on understandings of individual rights in the legal and theological texts of the twelfth- and early thirteenth-century Middle Ages, entitled ‘Sacred Rules, Secular Revelations: The Conceptions of Rights in Pre-Modern Europe’

An investigation of middle secondary students' mathematical conceptions of rate

This study identified four educationally critical aspects of ‘rate’ through analysis of phenomenographic, video-recorded interviews with Year 10 students. Further analysis indicated understandings in one representation or context were not necessarily transferable.

Reframing conceptions of contemporary literacy capabilities in pre-service primary teacher education

This chapter describes the challenges of integrating new technologies with literacy education in pre-service primary teacher education in Australia. The authors describe the policy context and regulatory mechanisms controlling pre-service education, including a national set of professional standards for graduate teachers, a new national curriculum for school students, the introduction of high stakes national assessment for school students, and the looming threat of decontextualized back-to-the-basics professional entry tests for aspiring teachers. The chapter includes three case studies of the authors’ pedagogical practices that attempt to reframe conceptions of the literacy capabilities of pre-service teachers to reflect the complex and sophisticated requirements of teachers in contemporary schooling. The authors conclude the chapter with a discussion of the implications of these case studies as they illustrate the ways that pre-service teachers can be scaffolded and supported to develop creative capacity and critical awareness of the kinds of literacies required in the digital age despite restrictive regimes.

Law, Theology, and Morality: Conceptions of the Rights to Relief of the Poor in the Twelfth and Thirteenth Centuries

This article presents an analysis of certain ways of thinking about law and its relationship to the poor, in particular the rights and entitlements of the poor to the basic necessities of life and the obligations of society to provide those necessities. It focuses on the works of Peter the Chanter and his “circle” at Paris in the late twelfth and early thirteenth centuries. Significant in their writings on the quandary between respect for private property and the need to allow those in need to take a share of this private property in order to survive is their negotiation of the intellectual boundaries and understandings between law, theology, and morality. In addition, an understanding of their discussions in light of canonistic and theological works of the time reveal a hitherto under-appreciated contribution to the “subjective rights” language in Peter the Chanter.

Australian primary in-service teachers’ conceptions of geography

This paper reports on the second part of a two pronged qualitative investigation that examines the ways in which Australian primary teachers conceptualise geography and geography teaching. In the first part of the project, 47 pre-service primary teachers were surveyed. In this paper, I draw on interviews with six in-service primary teachers to explore their experiences, conceptions and perceptions of geography. The findings indicate a noticeable difference between the conceptions of geography held by experienced teachers and those of early career, in-service teachers. Similar to the pre-service teachers studied in part one of this study, the early career teachers had a narrow, information-oriented conception of geography and geography education. Conversely, the experienced teachers portrayed more complex, relational and process-oriented perspectives. The paper concludes by exploring some of the implications for the implementation of the new National geography curriculum in Australia.

Australian primary pre-service teachers’ conceptions of geography

This article reports on the results of a survey of Australian primary pre-service teachers’ experiences, conceptions and perceptions of geography. Research was conducted with two cohorts of undergraduate primary pre-service teachers; one group in second year and another in the final year of a four-year teacher education course. The findings show congruence with similar studies conducted in the UK and indicate that pre-service teachers had a very narrow conception of geography and geography education; a conception that was information-oriented and focused on broad knowledge about the world and locational knowledge and skills. The article concludes by exploring some of the implications for the implementation of the new national geography curriculum in Australia and for primary pre-service geography teacher education more broadly.

From project supervision to advising: new conceptions of the practice

Project work has been a common feature of undergraduate degree programmes for many years. While it has been named in a variety of ways, it typically involves students undertaking a substantial learning activity that is partly self‐initiated and managed. More recently, programmes organised around the idea of work‐based learning partnerships have emerged. These can be regarded as programmes that rely on significant amounts of work‐based project work. This paper examines the implications of practices in these new programmes for project advising more generally. It argues that the conception of the role of academics in project work needs to change from one focused on project supervision to one of learning adviser. It identifies key features of this practice and discusses differences in advising from one context to another. It suggests that the activities in which academics engage need to be reappraised and that the skills and knowledge of those acting in the role of adviser be extended.

Application of cuckoo search for design optimization of heat exchangers

A wide variety of evolutionary optimization algorithms have been used by researcher for optimal design of shell and tube heat exchangers (STHX). The purpose of optimization is to minimize capital and operational costs subject to efficiency constraints. This paper comprehensively examines performance of genetic algorithm (GA) and cuckoo search (CS) for solving STHX design optimization. While GA has been widely adopted in the last decade for STHX optimal design, there is no report on application of CS method for this purpose. Simulation results in this paper demonstrate that CS greatly outperforms GA in terms of finding admissible and optimal configurations for STHX. It is also found that CS method not only has a lower computational requirement, but also generates the most consistent results.

Interrogating conceptions of “vulnerable youth” in theory, policy and practice

Young people who are considered ‘vulnerable’ or ‘at risk’ are a particular target of various policies, schemes and interventions. But what does vulnerability mean? Interrogating Conceptions of “Vulnerable Youth” explores this question in relation to various policy fields that are relevant to young people, as well for how this plays out in practice and how it is experienced by young people themselves. What makes this book unique is that most authors had the opportunity to jointly explore these issues during a two-day workshop, and their chapters are informed by their cross-agency and cross-discipline discussions, making for a nuanced and thoughtful set of contributions. This collection is highly recommended for researchers and research students in the social sciences, as well as professional staff working in youth policy and youth services, in government departments and in NGOs. “Those who are most vulnerable should receive our greatest moral attention. However, the translation of generalised moral principles into effective policy and programs has never been easy. Political interests have invariably intervened, leading to complex debates about how vulnerability should be defined, classified, measured and represented. In recent years, these debates have become further complicated, as nation-states around the world have preached austerity. This timely book suggests that the responsibility for protecting the vulnerable cannot be left to individuals, but demands collective action, through institutions such as education, health and welfare. It examines some of the ways in which public policies and programs represent those who are vulnerable, involving a range of assumptions about the social, economic and political conditions that produce their vulnerabilities.” From the Foreword by Professor Fazal Rizvi
