Cognitive engagement and questioning online

This chapter discusses a range of issues associated with supporting inquiry and deep reasoning while utilising information and communications technology (ICT). The role of questioning in critical thinking and reflection is considered in the context of scaffolding and new opportunities for ICT-enabled scaffolding identified. In particular, why-questioning provides a key point of focus and is presented as an important consideration in the design of systems that not only require cognitive engagement but aim to nurture it. Advances in automated question generation within intelligent tutoring systems are shown to hold promise for both teaching and learning in a range of other applications. While shortening attention spans appear to be a hazard of engaging with digital media cognitive engagement is presented as something with broader scope than attention span and is best conceived of as a crucible within which a rich mix of cognitive activities take place and from which new knowledge is created.

Thermal profile of a near-adiabatic compression process in a cylindrical tube and establishment of critical control elements for repeatable process control

The compressed gas industry and government agencies worldwide utilize "adiabatic compression" testing for qualifying high-pressure valves, regulators, and other related flow control equipment for gaseous oxygen service. This test methodology is known by various terms including adiabatic compression testing, gaseous fluid impact testing, pneumatic impact testing, and BAM testing as the most common terms. The test methodology will be described in greater detail throughout this document but in summary it consists of pressurizing a test article (valve, regulator, etc.) with gaseous oxygen within 15 to 20 milliseconds (ms). Because the driven gas1 and the driving gas2 are rapidly compressed to the final test pressure at the inlet of the test article, they are rapidly heated by the sudden increase in pressure to sufficient temperatures (thermal energies) to sometimes result in ignition of the nonmetallic materials (seals and seats) used within the test article. In general, the more rapid the compression process the more "adiabatic" the pressure surge is presumed to be and the more like an isentropic process the pressure surge has been argued to simulate. Generally speaking, adiabatic compression is widely considered the most efficient ignition mechanism for directly kindling a nonmetallic material in gaseous oxygen and has been implicated in many fire investigations. Because of the ease of ignition of many nonmetallic materials by this heating mechanism, many industry standards prescribe this testing. However, the results between various laboratories conducting the testing have not always been consistent. Research into the test method indicated that the thermal profile achieved (i.e., temperature/time history of the gas) during adiabatic compression testing as required by the prevailing industry standards has not been fully modeled or empirically verified, although attempts have been made. This research evaluated the following questions: 1) Can the rapid compression process required by the industry standards be thermodynamically and fluid dynamically modeled so that predictions of the thermal profiles be made, 2) Can the thermal profiles produced by the rapid compression process be measured in order to validate the thermodynamic and fluid dynamic models; and, estimate the severity of the test, and, 3) Can controlling parameters be recommended so that new guidelines may be established for the industry standards to resolve inconsistencies between various test laboratories conducting tests according to the present standards?

A Delphi study on the critical sustainability criteria and indicators for Australian road infrastructure projects

With increasing media exposure and evidence of environmental impacts, it is increasingly recognized that incorporating sustainability principles in construction works is both crucial and beneficial. However a recent survey reveals that among stakeholders of infrastructure projects such as roads, there is no common understanding on what constitutes sustainability in real-life projects. Sustainability has been interpreted widely and differently and as a result, sustainability outcomes are not tangible at the project level or often neglected. Under such conditions, policies and strategies on sustainability remain largely ideological and cannot be sufficiently reflected in the actual project delivery. The major difficulty of this sustainability pursuit lies in the lack of consensus among the experts on sustainability criteria and indicators. To move ahead, these criteria and indicators are to be agreed upon. This paper reviews the sustainable infrastructure development, its criteria and indicators, focusing on road infrastructure context. It goes on to introduce a Delphi study, an integral part of a QUT research, aimed at identifying critical sustainability criteria and indicators for Australian road infrastructure projects. It paves the way for further identification of solutions for each critical indicator at a subsequent stage. The criteria, indicators and solutions will be encapsulated into a decision making framework for the enhancement of sustainability deliverables. By doing so, the research will promote more integrated thinking of and consistent approaches to the sustainability agenda in road and highway infrastructure projects in Australia.

'Homes for Life' : a critical ecological study of an independent living project

In this paper, an ‘ecological’ lens is applied to an independent living project aiming to provide ‘homes for life’ for adult children with disabilities. The qualities of the project as ecological praxis are highlighted along with the implications for an open-ended enquiry into ecologies for and of the interior. In terms of the ecological concern for intimate modes of being, interior design is shown to be well placed through its association with environments in which people spend most of their life and through powerful concepts such as ‘interiority’ and ‘home’ which link to fundamental existential notions of ‘self ’ and ‘identity’. However, despite the interior being a significant generative force, this has not happened to the exclusion of other disciplines. Ignoring territorial urges to claim areas and concepts as one’s own, the paper describes how the project has actively encouraged design disciplines to trespass in each other’s territories. Ecologies for and of the interior, while recognising the need for discipline emphasis, also demand an integrated and collective approach through what is in effect transdisciplinary practice.

Setting a new agenda: Developing an Aboriginal and Torres Strait Islander women's health strategy

The Australian National Aboriginal and Torres Strait Islander Women’s Health Strategy was developed to reflect the health priorities of Aboriginal and Torres Strait Islander women, as identified by Aboriginal and Torres Strait Islander women themselves. This article describes the process used by the Australian Women’s Health Network to develop the strategy. The women involved in the research used the talking circle method and engaged with Aboriginal and Torres Strait Islander women through a process referred to as ‘talkin’ up’, where women ‘talk back’ to one another about issues that matter to them. In this article, we describe the power of the talkin’ up process, as a way for Aboriginal and Torres Strait Islander women to identify their own issues, discuss them in context and talk in a culturally safe environment. The strategy which emerged from this process is an accurate reflection of the issues that are important to Australian Indigenous women and highlights the improvements needed in Aboriginal and Torres Strait Islander women’s health to strengthen and underpin women’s health, Indigeneity and their sense of well-being as Aboriginal and Torres Strait Islander women.

Voices of experience : opportunities to influence creatively the designing of school libraries

Using a critical ethnographic approach this study investigates the potential for multiple voices of experience, of educators, designers/architects, education facility planners and students/learners, to influence creatively the designing of school libraries. School libraries are considered as social and cultural entities within the contexts of school life and of wider society. It is proposed that school library designing is a social interaction of concern to those influenced by its practices and outcomes. School library designing is therefore of significance to educators and students as well as to those with professionally accredited involvement in school library designing, such as designers/architects and education facility planners. The study contends that current approaches to educational space designing, including school libraries, amplify the voices of accredited designers and diminish or silence the voices of the user participants. The study is conceptualised as creative processes of discovery, through which attention is paid to the voices of experience of user and designer participants, and is concerned with their understandings and experiences of school libraries and their understandings and experiences of designing. Grounded theory coding (Charmaz) is used for initial categorising of interview data. Critical discourse analysis (CDA, Fairclough) is used as analytical tool for reflection on the literature and for analysis of the small stories gathered through semi-structured interviews, field observations and documents. The critical interpretive stance taken through CDA, enables discussions of aspects of power associated with the understandings and experiences of participants, and for recognition of creative possibilities and creative influence within and beyond current conditions. Through an emphasis on prospects for educators and students as makers of the spaces and places of learning, in particular in school libraries, the study has the potential to inform education facility designing practices and design participant relationships, and to contribute more broadly to knowledge in the fields of education, design, architecture, and education facility planning.

How do the learning outcomes of students compare in units with different levels of practical work? A comparative study about the relation between Problem-­Based Learning and assessment approaches

The literature supporting the notion that active, student-centered learning is superior to passive, teacher-centered instruction is encyclopedic (Bonwell & Eison, 1991; Bruning, Schraw, & Ronning, 1999; Haile, 1997a, 1997b, 1998; Johnson, Johnson, & Smith, 1999). Previous action research demonstrated that introducing a learning activity in class improved the learning outcomes of students (Mejias, 2010). People acquire knowledge and skills through practice and reflection, not by watching and listening to others telling them how to do something. In this context, this project aims to find more insights about the level of interactivity in the curriculum a class should have and its alignment with assessment so the intended learning outcomes (ILOs) are achieved. In this project, interactivity is implemented in the form of problem- based learning (PBL). I present the argument that a more continuous formative feedback when implemented with the correct amount of PBL stimulates student engagement bringing enormous benefits to student learning. Different levels of practical work (PBL) were implemented together with two different assessment approaches in two subjects. The outcomes were measured using qualitative and quantitative data to evaluate the levels of student engagement and satisfaction in the terms of ILOs.

(Un)doing gender : ways of being in an age of uncertainty

Children’s literature has conventionally and historically been concerned with identity and the often tortuous journey to becoming a subject who is generally older and wiser, a journey typically characterised by mishap, adventure, and detours. Narrative closure in children’s and young adult novels and films typically provides a point of self-realisation or self-actualisation, whereby the struggles of finding one’s “true” identity have been overcome. In this familiar coming-of-age narrative, there is often an underlying premise of an essential self that will emerge or be uncovered. This kind of narrative resolution provides readers with a reassurance that things will work for the best in the end, which is an enduring feature of children’s literature, and part of liberal-humanism’s project of harmonious individuality. However, uncertainty is a constant that has always characterised the ways lives are lived, regardless of best-laid plans. Children’s literature provides a field of narrative knowledge whereby readers gain impressions of childhood and adolescence, or more specifically, knowledge of ways of being at a time in life, which is marked by uncertainty. Despite the prevalence of children’s texts which continue to offer normative ways of being, in particular, normative forms of gender behaviour, there are texts which resist the pull for characters to be “like everyone else” by exploring alternative subjectivities. Fiction, however, cannot be regarded as a source of evidence about the material realities of life, as its strength lies in its affective and imaginative dimensions, which nevertheless can offer readers moments of reflection, recognition, or, in some cases, reality lessons. As a form of cultural production, contemporary children’s literature is highly responsive to social change and political debates, and is crucially implicated in shaping the values, attitudes and behaviours of children and young people.

Some reflections about P2M : the place of the mirror

The purpose of this paper is to provide some insights about P2M, and more specifically, to develop some thoughts about Project Management seen as a Mirror, a place for reflection…, between the Mission of organisation and its actual creation of Values (with s: a source of value for people, organisations and society). This place is the realm of complexity, of interactions between multiple variables, each of them having a specific time horizon and occupying a specific place, playing a specific role. Before developing this paper I would like to borrow to my colleague and friend, Professor Ohara, the following, part of a paper going to be presented at IPMA World Congress, in New Delhi later this year in November 2005. “P2M is the Japanese version of project & program management, which is the first standard guide for education and certification developed in 2001. A specific finding of P2M is characterized by “mission driven management of projects” or a program which harness complexity of problem solving observed in the interface between technical system and business model.” (Ohara, 2005, IPMA Conference, New Delhi) “The term of “mission” is a key word in the field of corporate strategy, where it expresses raison d’être or “value of business”. It is more specifically used for expressing “the client needs” in terms of a strategic business unit. The concept of mission is deemed to be a useful tool to share essential content of value and needs in message for complex project.” (Ohara, 2005, IPMA Conference, New Delhi) “Mission is considered as a significant “metamodel representation” by several reasons. First, it represents multiple values for aspiration. The central objective of mission initiative is profiling of ideality in the future from reality, which all stakeholders are glad to accept and share. Second, it shall be within a stretch of efforts, and not beyond or outside of the realization. Though it looks like unique, it has to depict a solid foundation. The pragmatic sense of equilibrium between innovation and adaptation is required for the mission. Third, it shall imply a rough sketch for solution to critical issues for problems in reality.” (Ohara, 2005, IPMA Conference, New Delhi) “Project modeling” idea has been introduced in P2M program management. A package of three project models of “scheme”, “system” and “service” are given as a reference type program. (Ohara, 2005, IPMA Conference, New Delhi) If these quotes apply to P2M, they are fully congruent with the results of the research undertaken and the resulting meta-model & meta-method developed by the CIMAP, ESC Lille Research Centre in Project & Program Management, since the 80’s. The paper starts by questioning the common Project Management (PM) paradigm. Then discussing the concept of Project, it argues that an alternative epistemological position should be taken to capture Page 2 / 11 the very nature of the PM field. Based on this, a development about “the need of modelling to understand” is proposed grounded on two theoretical roots. This leads to the conclusion that, in order to enables this modelling, a standard approach is necessary, but should be understood under the perspective of the Theory of Convention in order to facilitate a situational and contextual application.

Critical thinking about the uses of research

One of the promises of New Labour was that government policy would be grounded in 'evidence based research'. In recent years some academics have come to question whether the government has delivered on this promise. Professors Reece Walters and Tim Hope offer two contributions to this debate, arguing that rather than the 'evidence base', it is political considerations that govern the commissioning, production and dissemination of Home Office research. As the first monograph in our 'Evidence based policy series' Critical thinking about the uses of research carries a thought provoking set of arguments.

Can sociologists do critical research

This work offers a critical introduction to sociology for New Zealand students. Written in an accessible narrative style, it seeks to challenge and debunk students' assumptions about key elements of their social worlds, encouraging them to develop a "critical imagination" as a tool to identify broader social themes in personal issues.

Quality metrics for assessing security-critical computer programs

Existing secure software development principles tend to focus on coding vulnerabilities, such as buffer or integer overflows, that apply to individual program statements, or issues associated with the run-time environment, such as component isolation. Here we instead consider software security from the perspective of potential information flow through a program’s object-oriented module structure. In particular, we define a set of quantifiable "security metrics" which allow programmers to quickly and easily assess the overall security of a given source code program or object-oriented design. Although measuring quality attributes of object-oriented programs for properties such as maintainability and performance has been well-covered in the literature, metrics which measure the quality of information security have received little attention. Moreover, existing securityrelevant metrics assess a system either at a very high level, i.e., the whole system, or at a fine level of granularity, i.e., with respect to individual statements. These approaches make it hard and expensive to recognise a secure system from an early stage of development. Instead, our security metrics are based on well-established compositional properties of object-oriented programs (i.e., data encapsulation, cohesion, coupling, composition, extensibility, inheritance and design size), combined with data flow analysis principles that trace potential information flow between high- and low-security system variables. We first define a set of metrics to assess the security quality of a given object-oriented system based on its design artifacts, allowing defects to be detected at an early stage of development. We then extend these metrics to produce a second set applicable to object-oriented program source code. The resulting metrics make it easy to compare the relative security of functionallyequivalent system designs or source code programs so that, for instance, the security of two different revisions of the same system can be compared directly. This capability is further used to study the impact of specific refactoring rules on system security more generally, at both the design and code levels. By measuring the relative security of various programs refactored using different rules, we thus provide guidelines for the safe application of refactoring steps to security-critical programs. Finally, to make it easy and efficient to measure a system design or program’s security, we have also developed a stand-alone software tool which automatically analyses and measures the security of UML designs and Java program code. The tool’s capabilities are demonstrated by applying it to a number of security-critical system designs and Java programs. Notably, the validity of the metrics is demonstrated empirically through measurements that confirm our expectation that program security typically improves as bugs are fixed, but worsens as new functionality is added.

Teaching undergraduate students community nursing : using action research to increase engagement and learning

Nurses play a pivotal role in responding to the changing needs of community health care. Therefore, nursing education must be relevant, responsive, and evidence based. We report a case study of curriculum development in a community nursing unit embedded within an undergraduate nursing degree. We used action research to develop, deliver, evaluate, and redesign the curriculum. Feedback was obtained through self-reflection, expert opinion from community stakeholders, formal student evaluation, and critical review. Changes made, especially in curriculum delivery, led to improved learner focus and more clearly linked theory and practice. The redesigned unit improved performance, measured with the university's student evaluation of feedback instrument (increased from 0.3 to 0.5 points below to 0.1 to 0.5 points above faculty mean in all domains), and was well received by teaching staff. The process confirmed that improved pedagogy can increase student engagement with content and perception of a unit as relevant to future practice.
