Freehand 3D Scanning in a Mobile Environment using Video

This work is motivated by two important trends in consumer computing: (i) the growing pervasiveness of mobile computing devices, and (ii) the users’ desire for increasingly complex but readily acquired and manipulated information content. Specifically, we develop and describe a system for 3D model creation of an object, using only a standard mobile device such as a smart phone. Our approach applies the structured light projection methodology and exploits multiple image input such as frames from a video sequence. In comparison with previous work, a significant further challenge addressed here is that of lower quality input data and limited hardware (processing power and memory, camera and projector quality). Novelties include: (i) a comparison of projection pattern detection approaches in the context of a mobile environment – a robust method combining colour detection and a phase congruency descriptor is evaluated, (ii) a model for single view reconstruction which exploits epipolar, coplanarity and topological constraints, (iii) the use of mobile device sensor data in the iterative closest point algorithm used to register multiple partial 3D reconstructions, and (iv) two heuristics for determining the order in which buffered single view based reconstructions are merged. Our experiments demonstrate that visually appealing results are obtained in a speedy manner which does not require specialist knowledge or expertise from the user.

Virtual worlds in Australian and New Zealand higher education: Remembering the past, understanding the present and imagining the future

3D virtual reality, including the current generation of multi-user virtual worlds, has had a long history of use in education and training, and it experienced a surge of renewed interest with the advent of Second Life in 2003. What followed shortly after were several years marked by considerable hype around the use of virtual worlds for teaching, learning and research in higher education. For the moment, uptake of the technology seems to have plateaued, with academics either maintaining the status quo and continuing to use virtual worlds as they have previously done or choosing to opt out altogether. This paper presents a brief review of the use of virtual worlds in the Australian and New Zealand higher education sector in the past and reports on its use in the sector at the present time, based on input from members of the Australian and New Zealand Virtual Worlds Working Group. It then adopts a forward-looking perspective amid the current climate of uncertainty, musing on future directions and offering suggestions for potential new applications in light of recent technological developments and innovations in the area.

Ways in which theory and practice are integrated in the pre-service teacher education practicum

This paper reports on a study into pre-service teachers’ perceptions about their professional development during practicum. The study examined to what extent, and how effectively, one group of pre-service teachers was able to integrate theory and practice during a three-week practicum in the first year of their degree. Data for this mixed methods study were drawn from one cohort of first-year students undertaking the Master of Teaching (MTeach), a graduate-level entry program in the Faculty of Education at an urban Australian university. Although there is a strong field of literature around the practicum in pre-service teacher education, there has been a limited focus on how pre-service teachers themselves perceive their development during this learning period. Further, despite widespread and longstanding acknowledgement of the “gap” between theory and practice in teacher education, there is still more to learn about how well the practicum enables an integration of these two dimensions of teacher preparation. In presenting three major findings of the study, this paper goes some way in addressing these shortcomings in the literature. First, opportunities to integrate theory and practice were varied, with many participants reporting supervision and scheduling issues as impacting on their capacity to effectively enact theory in practice. Second, participants’ privileging of theory over practice, identified previously in the literature as commonly characteristic of the pre-service teacher, was found in this study to be particularly prevalent during practicum. Third, participants overwhelmingly supported the notion of linking university coursework assessment to the practicum as a means of bridging the gap between, on the one hand, the university and the school and, on the other hand, theory and practice. The discussion and consideration of findings such as those reported in this paper are pertinent and timely, given the ratification of both the National Professional Standards for Teachers and the Initial Teacher Education Program Standards by the Australian Federal Government earlier this year. Within a number of the seven Professional Standards, graduate teachers are required to demonstrate knowledge and skills associated with both the theory and practice of teaching and with their effective integration in the classroom. To be nationally accredited, pre-service teacher education programs must provide evidence of enabling pre-service teachers to acquire such knowledge and skills.

Teaching in the iWorld: developing a repertoire of pedagogical discourse around the usage of touch screen devices in early years classrooms

 Touch-screen devices have been enthusiastically adopted by schools across Australia and Canada. Their ease of use means that they are accessible by very young children, and these children often have free access to these devices in their home, however the devices tend to be ‘domesticated’ in the school context (O’Mara and Laidlaw, 2011). In the short period of their availability, a plethora of educational applications have been developed for these devices. This paper addresses emergent themes from our 2011-2013 Canadian/Australian project, Literacy learning in playful spaces: using multi-modal strategies to develop narrative with young learners, funded by the Canadian Social Sciences and Humanities Research Council (Insight Development Grant). In our analysis of the discourse around the introduction of portable touch screen devices into school literacy classes (published texts, teacher interviews, classroom observations), we noted that much of the public discourse is slanted towards the idea of “teacher-proofing” the curriculum. Initially the teachers we have been working with saw the apps themselves as complete, as doing all the work and the discourse around the devices was around what apps are “best”, and “is there an app for that?” It was only with more experience and time that teachers were able to harness the range of affordances of the devices—their capacity for recording audio, video, pictures etc., and start to categorise the apps themselves. In this paper we suggest ways in which current literacy models might be used to develop a repertoire of pedagogical discourse around these devices, providing language and framings for teachers to think about how these new tools might best be used to enhance literacy teaching and learning.

Consumer involvement in the tertiary-level education of mental health professionals: a systematic review

A systematic review of the published work on consumer involvement in the education of health professionals was undertaken using the PRISMA guidelines. Searches of the CINAHL, MEDLINE, and PsychINFO electronic databases returned 487 records, and 20 met the inclusion criteria. Further papers were obtained through scanning the reference lists of those articles included from the initial published work search (n = 9) and contacting researchers in the field (n = 1). Thirty papers (representing 28 studies) were included in this review. Findings from three studies indicate that consumer involvement in the education of mental health professionals is limited and variable across professions. Evaluations of consumer involvement in 16 courses suggest that students gain insight into consumers' perspectives of: (i) what life is like for people with mental illness; (ii) mental illness itself; (iii) the experiences of admission to, and treatment within, mental health services; and (iv) how these services could be improved. Some students and educators, however, raised numerous concerns about consumer involvement in education (e.g. whether consumers were pursuing their own agendas, whether consumers' views were representative). Evaluations of consumer involvement in education are limited in that their main focus is on the perceptions of students. The findings of this review suggest that public policy expectations regarding consumer involvement in mental health services appear to be slowly affecting the education of mental health professionals. Future research needs to focus on determining the effect of consumer involvement in education on the behaviours and attitudes of students in healthcare environments.

Mono-cultural approach in multicultural education: mapping the contours of multicultural early childhood education in New Zealand

There has been an increase in research activities in multicultural early childhood education in New Zealand. This article provides a critical review of these activities. This is an attempt to unravel the aspirations and complexities associated with the educational policies and practices with children of culturally diverse backgrounds. The conclusion from this literature review is that despite the multicultural principles that support democracy and equitability in education in New Zealand, a monocultural approach is still pervasive in multicultural early childhood classrooms.

Education revolution or just plain revolting? Aboriginal prisoner education in Western Australia

The current Australian Federal government has voiced a commitment to an 'education revolution' and set targets for 'closing the gap' in education attainment for Aboriginal people. Unfortunately, this revolution appears to have bypassed prison education altogether with no mention of it in the publicly available policy documents. This is regrettable given the large numbers of Aboriginal people in custody and begs the question 'Are our incarcerated Indigenous citizens going to be excluded from any potential benefit of the 'revolution'?'

The place of place-based education in the Australian primary geography curriculum

The idea for this paper emerged from a recent qualitative investigation which examined the ways in which six Australian primary teachers conceptualised geography and geography teaching (Preston, 2014b). A finding of this research was a strong correlation between the breadth of geographical understandings and the years of experience and age of participants. For early career teachers, conceptions of geography were narrowly confined to information-oriented perceptions. Whereas, the two teachers, with more than 30 years in primary schools, portrayed much more complex understandings. Their conceptions depicted geography as process-oriented and in relational terms, that is, understandings of geography that recognise the interactions and interdependence of people and environments (Bradbeer, Healey, & Kneale, 2004). Both these experienced teachers were also committed to place-based, inquiry approaches to geography teaching and had been using placebased methodologies long before it became a new movement in education (Morgan, 2009, p. 521 ). This prompted me to question why geography education seldom features in discourses of place-based education and to contemplate the oft-cited argument (at least in the United States) that the recent focus on curriculum standards is incompatible with locally responsive curriculum (Jennings, Swidler, & Koliba, 2005).
In order to answer these questions, I explore the intersections and divergences between place-based education and geography education in the Australian context. Drawing on Smith's (2002) and Gruenewald's (2003) conception of place-based education, and the new. Australian geography curriculum document, I argue that primary geography education has strong synergies with place-based education methodologies and aims. I further suggest that a geographical perspective can augment placebased education to enrich and broaden students' understandings of the complex interactions between and within places. This argument is balanced with a critical examination of the practice of geography education acknowledging that the tradition of fieldwork might benefit from placebased education approaches that enable more embodied, socially engaged interactions with places. Thus, I contend, place-based education and geography education are mutually supportive and each can extend the other. The paper concludes with a reflection on the challenges in Australia in preparing primary teachers for the implementation of the new (place-based) geography curriculum.

How do postgraduate qualifications in medical education impact on health professionals?

Background and Purpose: The number of degree-awarding programmes in medical education is steadily increasing. Despite the popularity and extensive investment in these courses, there is little research into their impact. This study investigated the perceived impact of an internationally-renowned postgraduate programme in medical education on health professionals’ development as educators.

Methods: An online survey of the 2008–12 graduates from the Centre for Medical Education, University of Dundee was carried out. Their self-reported shifts in various educational competencies and scholarship activities were analysed using non-parametric statistics. Qualitative data were also collected and analysed to add depth to the quantitative findings.

Results: Of the 504 graduates who received the online questionnaire 224 responded. Participants reported that a qualification in medical education had significantly (p&thinsp;<&thinsp;0.001) improved their professional educational practices and engagement in scholarly activities. Masters graduates reported greater impact compared to Certificate graduates on all items, including ability to facilitate curriculum reforms, and in assessment and feedback practices. Masters graduates also reported more engagement in scholarship activities, with significantly greater contributions to journals. These qualifications equally benefited all participants regardless of age. International graduates reported greater impact of the qualification than their UK counterparts.

Conclusion: A postgraduate medical education programme can significantly impact on the practices and behaviours of health professionals in education, improving self-efficacy and instilling an increased sense of belonging to the educational community.

Accountability and yardstick competition in the public provision of education

This paper explores the institutional change introduced by the public disclosure of an education development index (IDEB, Basic Education Development Index) in 2007 to identify the e ect of education accountability on yardstick competition in education spending for Brazilian municipalities. Our results are threefold. First, political incentives are pervasive in setting the education expenditures. The spatial strategic behavior on education spending is estimated lower for lame-ducks and for those incumbents with majority support at the city council. This suggests a strong relation between commitment and accountability which reinforces yardstick competition theory. Second, we nd a minor reduction (20%) in spatial interaction for public education spending after IDEB's disclosure | compared to the spatial correlation before the disclosure of the index. This suggests that public release of information may decrease the importance of the neighbors` counterpart information on voter`s decision. Third, exploring the discontinuity of IDEB`s disclosure rule around the cut-o of 30 students enrolled in the grade under assessment, our estimates suggest that the spatial autocorrelation | and hence yardstick competition | is reduced in 54%. Finally, an unforeseen result suggests that the disclosure of IDEB increases expenditures, more than 100% according to our estimates.
