The whats, whys and wherefores of home education and its regulation in Australia

This paper presents a unique summary of Australian research on home education, and an evaluation of current regulation in an Australian context. It begins with the recognition that home education is a legal alternative to school education in Australia. However it argues that legal definitions of home education do not properly reflect the practice of home education. This is illustrated by an examination of different educational approaches taken by home educators and research on the socialisation of home educated children in Australia. Research on who chooses home education, why people choose home education and the educational outcomes for home educated children is also discussed. Home educating families represent all family types, are found in rural, suburban and city locations, and choose home education for a variety ofreasons. Research indicates that Australian home educated children have positive educational and social experiences and outcomes. The question of whether and ifso the extent to which, home education should be regulated by the state is examined. The authors argue that whilst regulation is acceptable to protect a childr right to education, a more consistent regulatory framework is needed across Australia. It is argued that such aframework should facilitate and encourage children who are being home educated and should be flexible enough to accommodate the variety ofeducational approaches taken to home education.

Study of phase transformation and work hardening phenomenon during drilling of Ti-5553 and Ti-64

Titanium 5553 is a recently developed modification of Russian near-β titanium alloy VT-22 which has applications and potential particularly in the aerospace industry for such key components as landing gear. However, indications are that Ti-5553 has poorer machinability characteristics than other Ti alloys and a comprehensive and far-reaching analysis is a necessary research imperative. This paper presents the result of phase transformation and work hardening during drilling of Ti-5553 compared with Ti-64. The aim of this research work is to optimise the machining condition for Ti-5553, in which the β to a phase transformation, together with material work hardening could be fully understood. Analysis of machinability indicators, such as subsurface micrograph and hardness of drilled samples and drilling forces and torques, demonstrated that Ti-5553 generally has poorer machinability characteristics than Ti-64 and to some extent this variation has been quantified to allow for further and more detailed investigation.

The diffusion of policy in contexts of practice : flexible delivery in Australian vocational education and training

Significant changes have occurred over the last decade within the Australian Vocational Education and Training (VET) system. Not least amongst these has been a shift from a predominantly traditional face-to-face classroom model of programme delivery to more flexible models informed by the needs of clients. To lead this revolution, in 1991 the Australian Commonwealth and State Ministers for Training established the Flexible Delivery Working Party. A series of reports followed that sought to develop a policy framework, including a definition of flexible delivery, and its principles and characteristics. Despite these efforts, project funding and national staff development initiatives, several difficulties have been experienced in the ‘take-up’ of flexible delivery; problems that we argue are related to how the dissemination of innovative practice is conceived. Specifically, the literature and research on the diffusion of innovations points to the efficacy of informal social networks ‘in which individuals adopt the new idea as a result of talking with other individuals who have already adopted it’ (Valente, 1995, p. ix). Following a discussion of these issues, the article concludes by arguing the need for research of innovative practice transfer within VET in Australia, using qualitative case study in order to develop an in-depth and rich description of the process, and facilitate greater understanding of how it works in practice.

Prescribed fluid consumption and its effects on the physiology and work behaviour of Australian wildland firefighters

The present study examined firefighters' ability to consume a prescribed fluid volume (1200 ml · h-1) during a wildland fire suppression shift and compare the effect of this additional fluid prescription with self-paced drinking on firefighters' hydration status and plasma sodium concentration post shift and their heart rate, core temperature and physical activity during their shift. Thirty-four firefighters were evenly divided into two drinking groups: self paced and prescribed. Prescribed drinkers did not meet the required 1200 ml·h-1 intake, yet they consumed twice the fluid drank by the self-paced group. No differences were noted between groups in plasma sodium levels or hydration status before or after their shift. Prescribed fluid consumption resulted in significantly lower core temperature between two and six hours into the shift. This did not coincide with lower cardiovascular strain, greater physical activity when compared to the self-paced drinking group. Additional fluid consumption (above self-paced intake) did not improve firefighter activity or physiological function (though it may buffer rising core temperature). It seems that wildland firefighters, at least in mild to warm weather conditions, can self-regulate their fluid consumption and work behaviour to leave the fireground hydrated at the conclusion of their shift.

Narrative structure analysis with education and training videos for e-learning

This paper deals with the problem ofstructuralizing education and training videos for high-level semantics extraction and nonlinear media presentation in e-learning applications. Drawing guidance from production knowledge in instructional media, we propose six main narrative structures employed in education and training videos for both motivation and demonstration during learning and practical training. We devise a powerful audiovisual feature set, accompanied by a hierarchical decision tree-based classification system to determine and discriminate between these structures. Based on a two-liered hierarchical model, we demonstrate that we can achieve an accuracy of 84.7% on a comprehensive set of education and training video data.

Family-centred practice : empowerment, self-efficacy, and challenges for practitioners in early childhood education and care

Family-centred practice has been included in the Victoria, Australia Early Years Learning and Development Framework as a key practice principle for professionals working across all early years programs in that state. While this model of partnership for engaging and collaborating with families has long been used in the early intervention sector, the efficacy of adopting this model more widely across the wider early childhood education and care sector has not been explored. This article presents a discussion on family-centred practice as a model for engaging with families in the care and education of their children. Through an analysis of the underlying philosophy and an examination of the core principles and characteristics, the article explores family-centred practice as it sits within a broader theory of partnership. This analysis identifies that while there are essential principles and characteristics that position the model within a partnership framework, it is the notion of empowerment, an underpinning philosophy guiding the model, that adds another dimension to the way practitioners in early childhood education and care settings collaborate with families. In examining the broader early childhood context, the capacity of many early childhood practitioners to effectively implement empowering behaviours is challenged.
