Preventative health has become central to contemporary health care, identifying youth physical activity as a key factor in determining health and functioning. Schools offer a unique research setting due to distinctive methodological circumstances. However, school-based researchers face several obstacles in their endeavour to complete successful research investigations; often confronted with complex research designs and methodological procedures that are not easily amenable to school contexts. The purpose of this paper is to provide a practical guide for teachers (both teacher educators and teaching practitioners) seeking to conduct physical activity-based research in Australian school settings, as well as discuss research practices. The research enabling process has been divided into six phases: preparation; design; outcome measures; procedures; participants; and feedback. Careful planning and consideration must be undertaken prior to the commencement of, and during the research process, due to the complex nature of school settings and research processes that exist in the Australian context.

A persistent pattern of exclusion of young people with ‘mental disorders’ from school systems, despite the best intentions of schools and teachers, has prompted a call for a more reflexive understanding of their behaviours. This thesis, by describing how institutionally recognised ways of understanding can result in otherwise avoidable moral collisions and exclusion, produces new insights into the nature and processes of understanding required to promote inclusion. These insights were produced through an intensive qualitative examination of a violent classroom episode, identifying key points in the interaction that could make the difference between misrecognition and recognition, turning exclusion into inclusion.

In this paper, we report the preparation and characterisation of nanometer-sized TiO2, CdO, and ZnO semiconductor particles trapped in zeolite NaY. Preparation of these particles was carried out via the traditional ion exchange method and subsequent calcination procedure. It was found that the smaller cations, i.e., Cd2+ and Zn2+ could be readily introduced into the SI′ and SII′ sites located in the sodalite cages, through ion exchange; while this is not the case for the larger Ti species, i.e., Ti monomer [TiO]2+ or dimer [Ti2O3]2+ which were predominantly dispersed on the external surface of zeolite NaY. The subsequent calcination procedure promoted these Ti species to migrate into the internal surface of the supercages. These semiconductor particles confined in NaY zeolite host exhibited a significant blue shift in the UV-VIS absorption spectra, in contrast to the respective bulk semiconductor materials, due to the quantum size effect (QSE). The particle sizes calculated from the UV-VIS optical absorption spectra using the effective mass approximation model are in good agreement with the atomic absorption data.

A simple, sensitive, and validated method was developed for simultaneous determination of scoparone, capillarisin, rhein, and emodin in rat urine by ultra-performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry (UPLC-MS). The urinary samples were analyzed on an Acquity UPLC BEH C18 1.7 microm 2.1x50 mm column. Scoparone, capillarisin, rhein, and emodin in rat urine were simultaneously analyzed with good separation. The lower limits of detection were 6.0, 9.0, 7.0, and 3.0 ng/mL, and the lower limits of quantification were 20.0, 33.0, 24.0, and 12.0 ng/mL for scoparone, capillarisin, rhein, and emodin, respectively. The intra- and inter-day precisions (RSD) were less than 9%. The intra- and inter-accuracies were found to be in the range of 94.14-104.54% for scoparone, 101.72-107.34% for capillarisin, 95.24-103.59% for rhein, and 101.32-107.82% for emodin at three concentration levels. The absolute recoveries for scoparone, capillarisin, rhein, and emodin were not less than 77.0%. The developed method has been applied to determine scoparone, capillarisin, rhein, and emodin in rat urine after oral administration of Yin Chen Hao Tang preparation, a traditional Chinese medicine formulation widely used in China for treatment of jaundice and liver disorders.

A method for the rapid and simultaneous determination of 6,7-dimethylesculetin (CAS 120-08-1) and geniposide (CAS 24512-63-8) in rat plasma has been developed, using validated high performance liquid chromatography (HPLC) with solid phase extraction (SPE). The HPLC analysis was performed on a commercially available column (200 mm x 4.6 mm, 5 microm) with acetonitrile-methanol-0.1% aqueous formic acid as mobile phase and the UV detection at 343 nm and 238 nm for 6,7-dimethylesculetin and geniposide, respectively. The calibration curves for 6,7-dimethylesculetin and geniposide were linear over the range 0.4-25.6 microg/mL and 1.12-71.68 microg/mL, respectively. The lower limits of quantitation were 0.40 microg/ mL and 1.12 microg/mL, and the lower limits of detection were 0.06 microg/mL and 0.09 microg/ mL, respectively. The intra-day and inter-day precision for 6,7-dimethylesculetin and geniposide were < 5%, whereas the absolute recovery percentages were > 74%. A successful application of the developed HPLC analysis was demonstrated for the pharmacokinetic study of a Traditional Chinese Medicine formula of Yin Chen Hao Tang preparation.

The Australian Government’s current workforce reforms in early childhood education and care (ECEC) include a major shift in qualification requirements. The new requirement is that university four-year degree-qualified teachers are employed in before-school contexts, including child care. Ironically, recent research studies show that, in Australia, the very preservice teachers who are enrolled in these degree programs have a reluctance to work in childcare. This article reports on part of a larger study which is inquiring into how early childhood teacher professional identities are discursively produced, and provides a partial mapping of the literature. One preservice teacher’s comment provides the starting point, and the paper locates some the discourses that are accessible to preservice teachers as they prepare for the early years workforce. An awareness of the discursive field provides a sound background for preparing early childhood teachers. A challenge for the field is to consider which discourses are dominant, and how they potentially work to privilege work in some ECEC contexts over others.

Attention Deficit Hyperactivity Disorder (ADHD) has achieved celebrity status in many Western countries, yet despite considerable effort to prove its existence as a “real” disorder, ADHD still suffers from a crisis of legitimacy. Nonetheless, diagnosis and prescription of medication has grown at a phenomenal rate since the late 1980s, particularly in Western culture. Numerous accounts exist explaining how the ADHD diagnosis functions as a convenient administrative loophole, providing schools with a medical explanation for school failure, medication to sedate the “problem” into submission, or the means to eject children from mainstream classrooms. This book provides a more holistic interpretation of how to respond to children who might otherwise be diagnosed with and medicated for “ADHD”—a diagnosis which, whether scientifically valid or not, is unhelpful within the confine of the school. Training teachers to recognise and identify “ADHD symptoms” or to understand the functions of restricted pharmaceuticals will only serve to increase the number of children diagnosed and the sale of psychoactive medications. Research has shown that such activities will not help those children learn, nor will it empower their classroom teachers to take responsibility for teaching such children well. This book seeks to provide school practitioners with knowledge that is useful within the educational context to improve the educational experiences and outcomes for children who might otherwise receive a diagnosis of ADHD.

Nitrous oxide emissions from soil are known to be spatially and temporally volatile. Reliable estimation of emissions over a given time and space depends on measuring with sufficient intensity but deciding on the number of measuring stations and the frequency of observation can be vexing. The question of low frequency manual observations providing comparable results to high frequency automated sampling also arises. Data collected from a replicated field experiment was intensively studied with the intention to give some statistically robust guidance on these issues. The experiment had nitrous oxide soil to air flux monitored within 10 m by 2.5 m plots by automated closed chambers under a 3 h average sampling interval and by manual static chambers under a three day average sampling interval over sixty days. Observed trends in flux over time by the static chambers were mostly within the auto chamber bounds of experimental error. Cumulated nitrous oxide emissions as measured by each system were also within error bounds. Under the temporal response pattern in this experiment, no significant loss of information was observed after culling the data to simulate results under various low frequency scenarios. Within the confines of this experiment observations from the manual chambers were not spatially correlated above distances of 1 m. Statistical power was therefore found to improve due to increased replicates per treatment or chambers per replicate. Careful after action review of experimental data can deliver savings for future work.
Child-related factors that influence teacher-child relationships using an Australian national sample

This study assessed the extent to which child-related factors had an impact on teacher-child relationships in Australian childcare settings. Analyses used data from Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC). The sample consisted of 1577 two to three year old children (M= 33.9 months, SD=2.93; 51.5% male). Two separate hierarchical multiple regression analyses were conducted to examine the relation between teachers’ perceptions of their relationships with children and (a) gender, (b), indigenous status, (c), language background other than English, (d), socio-economic position, (e) special health care needs, (f) expression and receptive language concerns, (g) psychosocial competence and problems and (h) temperament factors (approach, persistence and reactivity). Results indicated that special health care needs, receptive language concerns and all three temperament scales (approach, persistence and reactivity) significantly predicted conflict in teacher-child relationships. Close relationships were predicted by being female, indigenous status, higher socio-economic position, not having a special health care need and no expressive language concerns.

This paper reports research about school libraries, teacher-librarians and their contribution to literacy development. It presents an evidenced based snapshot, from the principals’ perspective, of 27 school libraries in the Gold Coast area of Australia. These new Australian findings show: • an evidenced based snapshot of school libraries and teacher-librarians, from the principals’ perspective • indications that school NAPLAN scores for reading and writing were generally higher when (a) student to library staff ratios were lower (i.e. better) and (b) the school had a teacher-librarian. The research responds to the Australian Government inquiry into school libraries and teacher-librarians (2010-11) which identified an urgent need for current data about provision and staffing of school libraries and their influence on student literacy and learning. In light of the National plan for school improvement (Australian Government, 2013), the findings are of potential interest to education authorities, school leadership teams, teacher-librarians, teachers and researchers. They offer evidence to inform policy development, strategic planning and advocacy about school libraries and teacher-librarians in supporting the reading, literacy and learning needs of 21st century learners.

International research provides compelling evidence that school libraries and teacher-librarians make a significant contribution to student literacy and learning outcomes. After summarising previous research, this article presents recent research focused on Gold Coast schools. These new Australian findings present an evidenced based snapshot of school libraries and teacher-librarians, from the principals’ perspective. They indicate that school NAPLAN scores for reading and writing were generally higher when student-to-library staff ratios were lower (i.e. better) and when the school employed a teacher-librarian. In light of the National Plan for School Improvement, the findings are of potential interest to education authorities, policy makers, school leadership teams, teacher-librarians, teachers, parents and researchers. They offer evidence to inform policy development and strategic planning for school libraries and professional staffing.

This research study sought to understand why so many early career teachers in an Australian Religious Institute education sector were leaving teaching. Previous studies on early career teacher attrition across all sectors were based on supply and demand theory, as well as contemporary career theory, and identified various factors such as remuneration, student behaviour and school resourcing as influencing factors. These Australian Religious Institute education sector schools take pride in their good standing. The schools in this sector have worked at addressing many of the factors associated with early career teacher attrition yet despite their efforts they are also experiencing attrition of their early career teachers. A case study of the Queensland independent Catholic girls' school sector explored firstly, the construct of being a teacher in these schools, and secondly, the sociocultural discourses giving rise to unique situations contributing to early career teachers making the decision to leave teaching. Eight early career teachers who had left the profession for which they had recently trained, and eight long standing teachers who were still employed in the sector were interviewed to yield a rich data set. The interviews were conducted within a theoretical framework of what it means to be a teacher by Graham and Phelps (2003) and pedagogic identity and pedagogic practice as noted by Bernstein (2000). The distributive rules and the evaluative rules (Bernstein, 2000) provided the analytical framework to confirm that particular discourses, together with the ways in which the early career teachers realised being a teacher, were important factors in the decision not to remain in teaching. It emerged that being a teacher in the Queensland independent Catholic girls' school sector was complex and demanding. Being a teacher required long hours of personal time to realise the demands of teaching, a situation which did not fare well with the early career teachers who struggled to balance the requirements of teaching with their own personal time. Furthermore, evidence was found that the schools had multifaceted sociocultural discourses that the early career teacher research participants struggled to understand. In contrast, long standing teachers had, through time, experience and observation, developed skills that allowed them to navigate these complex discourses and thus remain long term in the sector. Another finding revealed the considerable dichotomy in how the charism of the schools (the unique way Catholic institutions transmit the beliefs and teachings of the Catholic Church) unfolded for students and staff. While these schools transmit their charism effectively to the students, it is ineffectively transmitted to early career teachers. In contemporary times when a majority of teachers in Australia are moving into their 50s and large numbers are retiring or resigning, (Australian Government, 2011; Australian Government Department of Education, 2007b) it is important for the long term viability of the independent Catholic school sector to retain a stable staff. This study demonstrates that if Catholic schools want to retain their unique identity in the education community and sustain their unique charisms, then they must adopt positive practices to support early career teachers.

The accumulated evidence from more than four decades of education research strongly suggests that parent involvement in schools carries significant benefits for students as well as for the success of schools (e.g., Henderson & Mapp, 2002). Governments in Australia and overseas have supported parent involvement in schools with a range of initiatives while parent groups have indicated a strong desire for expanded school roles that include participation in formal educational processes namely curriculum, pedagogy, and assessment. Research has also signalled the need for teachers to engage parents rather than adopt traditional parent-school involvement practices so that parents can participate as joint educators in their children's schooling alongside teachers (Pushor, 2001). Actually improving the quality of contact and relationships between parents and teachers to enable engagement however remains problematic. Coteaching and cogenerative dialoguing originally emerged as an innovative approach in the context of teaching secondary school science. Coteaching brings together the collective expertise of several individuals to expand learning opportunities for students while cogenerative dialogues refer to sessions in which participants talk, listen, and learn from one another about the process (Roth & Tobin, 2002a). Coteaching and cogenerative dialoguing reportedly benefits students academically and socially while rewarding educators professionally and emotionally through the support and collaboration they receive from fellow coteachers. These benefits ensue because coteaching theoretically positions teachers at one another's elbows, providing new and different understandings about teaching based on first-hand perspectives and shared goals for assisting students to learn. This thesis proposes that coteaching and cogenerative dialoguing may provide a vehicle for improving quality of contact and relationships between parents and teachers. To investigate coteaching and cogenerative dialoguing as a parent-teacher engagement mechanism, interpretive ethnographic case study research was conducted involving two parents and a secondary school teacher. Sociological ideas, namely Bourdieu's (1977) fields, habitus, and capitals, together with multiple dialectical concepts such as agency|structure (Sewell, 1992) and agency|passivity (Roth, 2007b, 2010) were assembled into a conceptual framework to examine parent-teacher relationships by describing and explaining cultural production and identity construction throughout the case study. Video and audio recordings of cogenerative dialogues and cotaught lessons comprised the chief data sources. Data were analysed using qualitative techniques such as discourse and conversation analysis to identify patterns and contradictions (Roth & Tobin, 2002a). The use of quality criteria detailed by Guba and Lincoln (2005) gives credence to the way in which ethical considerations infused the planning and conduct of this research. From the processes of data collection and analyses, three broad assertions were proffered. The findings highlight the significance of using multiple coordinated dialectical concepts for analysing the affordances and challenges of coteaching and cogenerative dialogues that include parents and teachers. Adopting the principles and purposes of coteaching and cogenerative dialoguing promoted trusting respectful relationships that generated an equitable culture. The simultaneous processes and tensions between logistics and ethics (i.e., the logistics|ethics dialectic) were proposed as a new way to conceptualise how power was redistributed among the participants. Knowledge of positive emotional energy and ongoing capital exchange conceived dialectically as the reciprocal interaction among cultural, social, and symbolic capitals (i.e., the dialectical relationship of cultural|social|symbolic capital) showed how coteaching and cogenerative dialoguing facilitated mutual understandings, joint decision-making, and group solidarity. The notion of passivity as the dialectical partner of agency explained how traditional roles and responsibilities were reconfigured and individual and collective agency expanded. Complexities that surfaced when implementing the coteaching and cogenerative dialoguing approach were outweighed by the multiple benefits that accrued for all involved. These benefits included the development of community-relevant and culturally-significant curricula that increased student agency and learning outcomes, heightened parent self-efficacy for participating in and contributing to formal educational processes, and enhanced teacher professionalism. This case study contributes to existing theory, knowledge and practice, and methodology in the research areas of parent-teacher relationships, specifically in secondary schools, and coteaching and cogenerative dialoguing. The study is particularly relevant given the challenges schools and teachers increasingly face to meaningfully connect with parents to better meet the needs of educational stakeholders in times of continual, complex, and rapid societal change.

The purpose of this qualitative interpretative case study was to explore how the National Assessment Program – Literacy and Numeracy (NAPLAN) requirements may be affecting pedagogies of two Year 3, Year 5 and Year 7 teachers at two Queensland schools. The perceived problem was that standardised assessment NAPLAN practices and its growing status as a key measure of education quality throughout Australia has the potential to limit the everyday literacy and numeracy practices of teachers to instructional methods primarily focused on teaching to the test. The findings demonstrate how increased explicit teaching of NAPLAN content and procedural knowledge prior to testing has the potential to negatively impact on the teaching of everyday literacy and numeracy skills and knowledge that extend beyond those concerned with NAPLAN. Such teaching limited opportunity for what teachers reported as valued collaborative learning contexts aiming for long-term literacy and numeracy results.
