Analysis of detection performance in spectrum sensing optimisation for long sensing periods

Spectrum sensing optimisation techniques maximise the efficiency of spectrum sensing while satisfying a number of constraints. Many optimisation models consider the possibility of the primary user changing activity state during the secondary user's transmission period. However, most ignore the possibility of activity change during the sensing period. The observed primary user signal during sensing can exhibit a duty cycle which has been shown to severely degrade detection performance. This paper shows that (a) the probability of state change during sensing cannot be neglected and (b) the true detection performance obtained when incorporating the duty cycle of the primary user signal can deviate significantly from the results expected with the assumption of no such duty cycle.

goDesign travelling design workshop program for regional secondary students

goDesign Travelling Workshop Program for Regional Secondary Students was an initiative of Queensland University of Technology (QUT) and the Design Institute of Australia (DIA) Queensland Branch, which aligned with the DIA unleashed: Queensland design on tour 2010 Exhibition. It was designed be delivered by university design academics in state secondary schools in Chinchilla, Mt Isa, Quilpie, Emerald, Gladstone and Bundaberg between February and September 2010, to approximately 95 secondary students and 24 teachers from the subject areas of visual art, graphics and industrial technology and design. A talk by a visiting design practitioner whose work was displayed in the exhibition, also features in the final day of the program in each town, and student work from the workshop was displayed in the exhibition alongside the professional design work. The three-day workshop is a design immersion program for regional Queensland Secondary Schools, which responds to specific actions outlined in the Queensland Government Design Strategy 2020 to ‘Build Design Knowledge and Learning’ and ‘Foster a Design Culture’. Underpinned by a place-based approach and the integration of Dr Charles Burnette’s IDESIGN teaching model, the program gives students and teachers the opportunity to explore, analyse and reimagine their local town through a series of scaffolded problem solving activities around the theme of ‘place’. The program allows students to gain hands-on experience designing graphics, products, interior spaces and architecture to assist their local community, with the support of design professionals. Students work individually and in groups on real design problems learning sketching, making, communication, presentation and collaboration skills to improve their design process, while considering social, cultural and environmental opportunities. The program was designed to facilitate an understanding of the value of design thinking and its importance to regional communities, to give students more information about various design disciplines as career options, and provide a professional development opportunity for teachers. Advisory assistance for the program was gained through Kelvin Grove State College, Queensland Studies Authority and QMI/Manufacturing Skills Queensland Manager, Manufacturing & Engineering Gateway Schools Project.

Learning by design workshop

The Learning by Design Workshop Program 2010, a part of the Queensland Government Unlimited: Designing for the Asia Pacific Event Program, was a one-day professional development design thinking workshop run on October 9, 2011 at The Edge, State Library of Queensland for self-selected public and private secondary school teachers from the subject areas of Visual Art, Graphics and Industrial Technology and Design. Participants were drawn from a database of Brisbane and regional Queensland schools from the goDesign and Living City Workshop Programs. It aimed to generate leadership within schools for design-led education and creative thinking and give teachers a rare opportunity to work with professional designers to generate future strategies for design-based learning. Teachers were introduced to the concept of design thinking in education by international keynote speakers CJ Lim (Studio 8 Architects) and Jeb Brugmann (The Next Practice), national speaker Oliver Freeman (NevilleFreeman Agency) and three Queensland speakers, Alexander Loterztain, David Williams and Keith Holledge. Inspired by the Unlimited showcase exhibition Make Change: Design Thinking in Action and ‘Idea Starters’/teaching resources provided, teachers worked with a professional designer (from a discipline of architecture, interior design, industrial design, urban design, graphic design or landscape architecture) in ten random teams, to generate optimistic ideas for the Ideal City of tomorrow, each considering a theme – Food, Water, Transport, Ageing, Growth, Employment, Shelter, Health, Education and Energy. They then discussed how this process could be best activated and expanded on to build interest and knowledge in design thinking in the classroom. Assisted by illustrators, the teams prepared a visual presentation of their ideas and process from art materials provided. The workshop culminated in a video-taped interactive design charette to the larger group, which is intended to be utilised as a toolkit and praxis for teachers as part of the State Library of Queensland Design Minds Website Project.

Generation workshop 2010

The Generation Workshop Program 2010, a part of the Queensland Government Unlimited: Designing for the Asia Pacific Event Program, consisted of two one-day intensive design thinking workshops run on October 7-8, 2011 at The Edge, State Library of Queensland, for 100 senior secondary students and 20 secondary teachers self-selected from the subject areas of Visual Art, Graphics and Industrial Technology and Design. Participants were drawn from a database of Brisbane and regional Queensland private and public schools from the goDesign and Living City Workshop Programs. The workshop aimed to facilitate awareness in young people of the role of design in society and the value of design thinking skills in solving complex problems facing the Asia Pacific Region, and to inspire the generation of strategies for our future cities. It also aimed to encourage the collaboration of professional designers with secondary schools to inspire post-secondary pathways and idea generation for education. Inspired by international and national speakers Bunker Roy (Barefoot College) and Hael Kobayashi (Associate Producer on "Happy Feet" film for Australia's Animal Logic), the Unlimited showcase exhibition Make Change: Design Thinking in Action and ‘Idea Starters’/teaching resources provided, students worked with a teacher in ten random teams, to generate optimistic strategies for the Ideal City of tomorrow, each considering a theme – Food, Water, Transport, Ageing, Growth, Employment, Shelter, Health, Education and Energy. Each team of 6 was led by a professional designer (from the discipline of architecture, interior design, industrial design, urban design, graphic design or landscape architecture) who was a catalyst for driving the student creative thinking process. Assisted by illustrators, the teams prepared a visual presentation of their idea from art materials provided. The workshop culminated in a video-taped interactive design chatter to the larger group, which will be utilised as a toolkit and praxis for teachers as part of the State Library of Queensland Design Minds Project. Photos of student design work were published on the Unlimited website.

Transforming habitus: Changing self, changing school

Since 2004, Australian Indigenous (Aboriginal and Torres Strait Islander) students at a low socioeconomic area Australian urban secondary school have used participatory action research to investigate issues of disengagement and absenteeism among their peers. Their research revealed that Indigenous students, who made up about 8% to 10% of the school’s population lacked a sense of belonging to the school. The researchers also revealed an apparent official disregard of the academic or sporting achievements of Indigenous students and, more disturbingly, their presence within the school. The young researchers followed up their findings with action to address the issues. These actions have resulted in a positive change of culture across the whole school, with Indigenous students now able to express pride in their heritage and feel some degree of ownership of the school.

Disobedient Citizens : Press Depictions of Striking School Teachers in NSW and Anti-Vietnam War Demonstrators in NSW and Victoria in 1968

Across Australia in 1968, students demonstrating against the Vietnam War engaged in confrontational behaviour. The metropolitan daily newspapers,the most important source of news for most people, enthusiastically reported the scenes. The demonstrations were exciting. Sensational headlines and photographs captured the interest of readers and influenced their opinions. But radical opposition to government policies at the time was not limited to university students opposing the Vietnam War. Teachers had become increasingly critical of conditions in schools, with Victorian secondary school teachers having stopped work on a number of occasions since 1965. In October 1968, both primary and secondary school teachers in New South Wales participated in eastern Australia’s first state-wide teachers’ strike. As Sydney’s Sun commented on 1 October 1968, “The teachers’ strike threw the ... education system into chaos ... A huge proportion of the State’s 2764 schools were silent and empty.” Similarities with the anti-war demonstrations were obvious. Although not as confrontational, the New South Wales teachers’ strike was a publicity-seeking action. This examination of the teachers’ more restrained, but more effective, approach to challenging government policies provides a new voice and vision to our understandings of the diverse nature of radicalism in Australia in the 1960s.

Front page schools, back page schools : a case study of factors perceived to affect academic performance in five Papua New Guinea secondary schools

Papua New Guinea has reformed its colonial established education system and made huge investments with the help of donors to achieve equal access and quality education for all its citizens. Despite this national aspiration and these policy reforms and investments, secondary schools that enrol grade 9 students who are relatively equal in education ability show huge disparities in their grade 10 academic performances. This study examined perceptions of students, teachers and principals regarding factors affecting the disparity in academic performance in the context of a developing country. The central question for the study is: What are the perceptions of students and teachers of the factors that affect disparities in secondary schools' academic performance? This qualitative case study involved two high and three low academic performing secondary schools in Western Highlands Province of Papua New Guinea. Primary data were collected through focus groups and semi-structured interviews involving 112 participants. Students and teachers are key participants in this study, as it intends to find out the realities of schools, yet they are an under-researched group. A postcolonial and sense of community conceptual framework was developed for the analysis of the participants. perceptions. In addition, scholarship on school effectiveness and equity in education informed the interpretation of the findings. Three themes were evident in participants. views. First, participants expressed their view that differences in academic performance were related to the adequacy and equitability of resources. The inequities in resource inputs led some of them to coin the metaphor of .back page and front page. schools. Second, many expressed the view that deficiencies in implementing bilingual education, given the difficulty of catering for 800 vernacular languages, contribute to poor English proficiency and subsequent poor academic performance. Finally, participants believed that, in order to have a positive school culture, it is necessary for educators to recognise and respect contemporary students. identities, communal/tribal membership and needs. This study has implications for national education policy on resource allocation to address equality and equity, bilingual education and teacher education. Moreover, as the study found that high academic performance in this context is also influenced by intra-school social relationships, these relationships need to be nurtured. When appropriately nurtured, they become an important factor in sustaining quality education for all secondary school students. This thesis has laid the foundations for further research and invites further investigations into policy and implementation of school reforms aimed at improving academic achievement.

Educational stress among Chinese adolescents : individual, family, school and peer influences

Educational stress is common among school children and adolescents, especially in Asian countries. This study aims to identify factors associated with perceived educational stress among students in China. A cross-sectional questionnaire survey was conducted with 1627 students (Grades 7–12) from six secondary schools in rural and urban areas of Shandong Province. A wide range of individual, family, school and peer factors were associated with stress measured using the Educational Stress Scale for Adolescents (ESSA). Rural school location, low school connectedness, perceived poor academic grades, female gender, older age and frequent emotional conflicts with teachers and peers were among the strongest correlates, and most of them are school- or study-related. Unexpectedly, family and parental factors were found to have little or no association with children’s perceived educational stress. These findings may offer directions for interventions in secondary school settings.

Broadening horizons : an emerging research agenda modelling design led innovation across secondary education

A re-examination of design education at all levels is needed to ensure global economic competitiveness and social and environmental sustainment. This paper presents an emerging research agenda modelling design led innovation approaches from the business sector to secondary education curriculum. To do this, a review of literature is provided and current knowledge gaps surrounding design education are detailed. A regional secondary school design immersion program is outlined as a future research case study using action research. A framework and recommendations for developing and delivering pedagogical approaches for 21st century skill outcomes in secondary education are briefly introduced and future research objectives are overviewed and discussed.

Greek or not : the use of symbols and abbreviations in mathematics

The use of symbols and abbreviations adds uniqueness and complexity to the mathematical language register. In this article, the reader’s attention is drawn to the multitude of symbols and abbreviations which are used in mathematics. The conventions which underpin the use of the symbols and abbreviations and the linguistic difficulties which learners of mathematics may encounter due to the inclusion of the symbolic language are discussed. 2010 NAPLAN numeracy tests are used to illustrate examples of the complexities of the symbolic language of mathematics.

'These are my photos of when I was little' : Locating Media Arts in the Primary School Curriculum

‘Media Arts’ has been included as a fifth area of the Arts for the Australian Curriculum which will become mandatory learning for all Australian children from pre-school to Year Six (Y6) from 2014. The current curriculum design is underpinned by an approach familiar to media educators who combine creative practice and critical response to develop students’ media literacies. Media Arts within the Australian Curriculum will place Australia at the forefront of international efforts to promote media education as an entitlement for all children. Even with this mandated endorsement, however, there remains ongoing debate about where to locate media education in school curricula. Historically, media education in Australia has been approached through diverse curriculum activities at the secondary school level. These include subject English’s critical literacy objectives; vocationally oriented media and technology education or ICTs education; and Arts courses using new media technologies for creativity. In this chapter we consider the possibilities and challenges for Media Arts, specifically for primary school student learning. We draw on empirical evidence from a research project that has trialled a Media Arts curriculum with students attending a primary school in a low socio-economic status and culturally diverse community on the outskirts of Brisbane, Queensland.

Developing capabilities for social inclusion : engaging diversity through inclusive school communities

The effort to make schools more inclusive, together with the pressure to retain students until the end of secondary school, has greatly increased both the number and educational requirements of students enrolling in their local school. Of critical concern, despite years of research and improvements in policy, pedagogy and educational knowledge, is the enduring categorisation and marginalization of students with diverse abilities. Research has shown that it can be difficult for schools to negotiate away from the pressure to categorise or diagnose such students, particularly those with challenging behaviour. In this paper, we highlight instances where some schools have responded to increasing diversity by developing new cultural practices to engage both staff and students; in some cases, decreasing suspension while improving retention, behaviour and performance.

School libraries, teacher-librarians and their contribution to student literacy development in Gold Coast schools

This is the first research focusing on Gold Coast school libraries and teacher- librarians. It presents a detailed picture of library provision and staffing at a representative group of 27 government and non-government schools at the Gold Coast. It shows links between employment of a teacher-librarian and higher NAPLAN reading and writing scores. And it presents the principals’ generally positive views about teacher-librarians’ contribution to reading and literacy at their schools. The findings respond in part to the recent government inquiry’s call (House of Representatives, 2011) for research about the current staffing of school libraries in Australia, and the influence of school libraries and teacher-librarians on students’ literacy and learning outcomes. While the study has focused on a relatively small group of school libraries, it has produced a range of significant outcomes: • An extensive review of international and Australian research showing impacts of school libraries and teacher-librarians on students’ literacy and learning outcomes • Findings consistent with international research showing: - An inverse relationship between lower student to EFT library staff ratio and higher school NAPLAN scores for reading and writing - Schools that employ a teacher-librarian tend to achieve school NAPLAN scores for respective year levels that are higher than the national mean It is anticipated that the study’s findings will be of interest to education authorities, school leadership teams, teacher-librarians, teachers and researchers. The findings provide evidence to: • inform policy development and strategic planning for school libraries that respond to the literacy development needs of 21st century learners • inform school-based management of school libraries • inform curriculum development and teacher-librarian practice • support further collaborative research on a State or national level • enhance conceptual understandings about relationship(s) between school libraries, teacher-librarians and literacy/information literacy development • support advocacy about school libraries, teacher-librarians and their contribution to literacy development and student learning in Australian schools SLAQ President Toni Leigh comments: “It is heartening to see findings which validate the critical role teacher-librarians play in student literacy development and the positive correlation of higher NAPLAN scores and schools with a qualified teacher-librarian. Also encouraging is the high percentage of school principals who recognise the necessity of a well resourced school library and the positive influence of these libraries on student literacy”. This research arises from a research partnership between School Library Association of Queensland (SLAQ) and Children and Youth Research Centre, QUT.

Pre-service Physical Education teachers and concerns regarding their ability to successfully facilitate school-based physical activity promotion strategies

Regular physical activity (PA) in youth has numerous immediate and long-term health benefits. With several studies indicating low levels of youth PA globally, schools settings have become increasingly critical settings for youth health promotion strategies. The role of physical education (PE) teachers has long been considered central to the facilitation of such strategies. However, PE teachers have a selfreported lack of knowledge, skills, understanding, and competence to successfully implement these strategies. Tertiary education programs are fundamental to adequately preparing, and shaping the attitudes and philosophies of future PE teachers towards their involvement within these programs. The aim of this investigation was to explore the beliefs and perceptions of future secondary school PE teachers, regarding their potential roles in future school-based programs designed to promote student PA. Fifty-seven (21 males and 36 females) pre-service PE teachers completed a series of open-ended survey questions concerning their perceptions towards participating in school-based PA promotion programs both as preservice during practicum, and prospectively as practising teachers. Responses were analysed thematically. Participants responded both positively and enthusiastically to both questions. Concerns regarding time, and the intention or expectation to participate in such programs were also key themes for pre-service and practicing teacher participation respectively. Critically in this study, participants did not identify any limitations which may impact upon their ability to successfully promote youth PA in school settings. This may indicate that participants have misconceptions regarding their ability to fulfil this role, or conversely, the deficiency of current PE teachers regarding school-based PA promotion has been recognised by the tertiary institution, and addressed to adequately prepare its students. School-based PA promotion is an integral element of pre-service PE teacher education, and ongoing professional development of practicing PE teachers. This trend is expected to continue in the future, in order to address ongoing public health concerns.

Physical activity promotion as a school priority : what do parents think?

The demands and responsibilities placed on schools in contemporary education systems are vast. However, with growing obesity levels and physical inactivity, the prevention of chronic disease has focused on youth populations, with schools playing the focal educative asset in this strategy. Parents play a decisive role in their child’s educational setting, and as fee and tax payers, are ultimately a consumer. Parents (82 males and 208 females) of secondary school children were recruited from three private (n=151) and two government schools (n=150) in Brisbane, Australia. The mean (standard deviation) age was 44.57 (6.21) years. Participants responded to a series of questions about physical activity at their child’s school, in addition to completing the International Physical Activity Questionnaire. Data were analysed using descriptive statistics, frequency distributions and logistic regressions. Parents were deemed sufficiently physically active if they participated in at least 150 minutes of moderate-to-vigorous physical activity per week. Overall, 83 (59.7%) parents from private and 60 (50.8%) parents from government schools were deemed sufficiently physically active. Concerning whether physical activity promotion should be a priority at their child’s school, 111 (73.5%) parents from private schools either agreed or strongly agreed, as opposed to 97 (64.7%) parents from government schools. Logistic regressions indicated that the concept of physical activity promotion being prioritised at schools was dependent on whether the child attended a private school (OR =1.34, z = 2.30, p = 0.02), and whether the participant was sufficiently active (OR =.71, z = -2.48, p = 0.01). Physical activity promotion within schools may provide substantial future benefits on a population scale. The demands on schools may need to be addressed to meet the needs of students and the desires of their parents.
