Variations in acculturation and Australian physical education teacher education students' receptiveness to an alternative pedagogical approach to games teaching

Background The development of intelligent, thinking performers as a central theme in Physical Education curriculum documents worldwide has highlighted the need for an evolution of teaching styles from the dominant reproductive approach. This has prompted an Australian university to change the content and delivery of a games unit within their Physical Education Teacher Education (PETE) course and adopt a productive student centred approach that is compatible with current curriculum directives. The significance of prospective physical educators’ biographies on their receptiveness to this pedagogical innovation was studied to help recognise and understand potential differences and subsequently guide programme development to help improve the impact of teacher education. Purpose To investigate whether past school and sporting experiences are powerful influences on Australian PETE recruits’ initial perspectives about effective physical education teaching practice and their receptiveness to an alternative pedagogical approach. Participants and Setting 49 first year pre-service PETE students (53% male; 47% female; mean age 18.88 ± 1.57 years) undertaking a compulsory unit on games teaching at an Australian university volunteered to take part in the study and were grouped according to their highest level of representation in games, either school/club (n=13), regional (n=20), or state/national (n=16). Students experienced the constraints-led approach as learners and teachers during an 8-week games unit informed by nonlinear pedagogy and underpinned by motor learning theory. Data collection and Analysis Prior to the commencement of the unit participants completed part A of a two part mixed response questionnaire aimed at gathering data about their physical education and sporting background. The data were summarised using descriptive statistics. Pre and post intervention, participants completed part B responding, via Likert Scale with their opinion of the importance of each sub-component of the traditional reproductive style for an effective games teaching session. This resulted in a traditional reproductive games teaching belief score. For each sub-component, participants were invited to respond in more detail to justify their opinions. A one-way between groups analysis of variance (ANOVA), Tukey’s HSD Post Hoc Test and a two - tailed, paired samples t test were used to analyse the quantitative data. Content analysis was used to analyse the qualitative data. Findings The traditional, reproductive approach was the most frequently reported teaching approach used by the physical education teachers and sports coaches of participants in all groups. Prior to the commencement of the alternate games unit, participants in each representative level group held very strong custodial traditional reproductive games teaching beliefs. After experiencing the alternative games unit there were statistically significant differences in the traditional reproductive games teaching belief mean scores for each group, This combined with participants’ qualitative responses indicated a receptiveness to the alternative pedagogy. Conclusions The results of this present study show that, contrary to previous research undertaken in North America, in Australia, it is possible for PETE educators to change beliefs in order to overcome the constraint of acculturation and provide PETE students with the knowledge, understanding and belief in an alternate approach to teaching games in physical education compatible with curriculum documents.

'Explain in plain English' questions revisited : data structures problems

Recent studies have linked the ability of novice (CS1) programmers to read and explain code with their ability to write code. This study extends earlier work by asking CS2 students to explain object-oriented data structures problems that involve recursion. Results show a strong correlation between ability to explain code at an abstract level and performance on code writing and code reading test problems for these object-oriented data structures problems. The authors postulate that there is a common set of skills concerned with reasoning about programs that explains the correlation between writing code and explaining code. The authors suggest that an overly exclusive emphasis on code writing may be detrimental to learning to program. Non-code writing learning activities (e.g., reading and explaining code) are likely to improve student ability to reason about code and, by extension, improve student ability to write code. A judicious mix of code-writing and code-reading activities is recommended.

Overcoming acculturation: Physical education recruits' experiences of an alternative pedagogical approach to games teaching

Background Physical education teacher education (PETE) programmes have been identified as a critical platform to encourage the exploration of alternative teaching approaches by pre-service teachers. However, the socio-cultural constraint of acculturation or past physical education and sporting experiences results in the maintenance of the status quo of a teacher-driven, reproductive paradigm. Previous studies have reported successfully overcoming the powerful influence of acculturation, resulting in a change in PETE students’ custodial teaching beliefs and receptiveness to alternative teaching approaches. However, to date, limited information has been reported about how PETE students’ acculturation shaped their receptiveness to an alternative teaching approach. This is particularly the case for PETE recruits identified in the literature as most resistant to change. Purpose To explore the features and experiences of an alternative games teaching approach that appealed to PETE recruits’ identified as most resistant to change, requiring a specific sample of PETE recruits with strong, custodial, traditional physical education teaching beliefs, and whom are high achieving sporting products of this traditional culture. The alternative teaching approach explored in this study is the constraints-led approach (CLA), which is similar operationally to TGfU, but distinguished by a neurobiological theoretical framework (nonlinear pedagogy) that informs learning design. Participants and Setting A purposive sample of 10 Australian PETE students was recruited for the study. All participants initially had strong, custodial, traditional physical education teaching beliefs, and were successful sporting products of this teaching approach. After experiencing the CLA as learners during a games unit, participants demonstrated receptiveness to the alternative pedagogy. Data Collection and Analysis Semi-structured interviews and written reflections were sources of data collection. Each participant was interviewed separately, once prior to participation in the games unit to explore their positive physical education experiences, and then again after participation to explore the specific games unit learning experiences that influenced their receptiveness to the alternative pedagogy. Participants completed written reflections about their personal experiences after selected practical sessions. Data were qualitatively analysed using grounded theory. Findings: Thorough examination of the data resulted in establishment of two prominent themes related to the appeal of the CLA for the participants: (i) psychomotor (effective in developing skill), and (ii), inclusivity (included students of varying skill level). The efficacy of the CLA in skill development was clearly an important mediator of receptiveness for highly successful products of a traditional culture. This significant finding could be explained by three key factors: the acculturation of the participants, the motor learning theory underpinning the alternative pedagogy and the unit learning design and delivery. The inclusive nature of the CLA provided a solution to the problem of exclusion, which also made the approach attractive to participants. Conclusion PETE educators could consider these findings when introducing an alternative pedagogy aimed at challenging PETE recruits’ custodial, traditional teaching beliefs. To mediate receptiveness, it is important that the learning theory underpinning the alternative approach is operationalised in a research-informed pedagogical learning design that facilitates students’ perceptions of the effectiveness of the approach through experiencing and or observing it working.

A Journey in the Landscape of Sustainable School Development “A Journey in the Landscape of Sustainable School Development” is a story of the Sorrila School development process. This research deals with a school development project as a process, and as a part of international projects on Education for Sustainable Development, with ENSI (Environment and School Initiatives) being the most important. The main purpose of the study was to analyze the change process as a general phenomenon as well as the learning connected to it. The research describes the development period 2001–2008 at the Sorrila Primary school. The research questions are as follows: 1. What did pupils learn during the research and development period? 2. How did the coordinating teacher develop personally? 3. How were the ENSI targets and other closely linked projects reached? 4. What was the feedback from the pupils, their parents and other teachers at the school? 5. How did the developing process proceed in 2001–2008? The method used was integrating action research, which also had ethnographical elements. Narrative was the form of the data as well as the manner of reporting. The method as a whole was integrating, ethnographical action research as a story. The research data consisted mostly of Knowledge Forum notes written by the teacher-researcher. Knowledge Forum is an Internetbased collaborative knowledge-building programme. Pupils’, parents’ and other teachers’ feedback, newspaper articles and students’ writings complied the data, which consists of material from seven years. Sustainable development was the basis of the school improvement. The targets of the United Nations Decade of Education for Sustainable Development (2005–2014) were part of the development projects. According to the research results the school was seen as part of complex systems where manifold and interactive learning took place. The learning of pupils, teachers and the school as a community can be characterised socioculturally. The school was able to reach a level of collaborative transformative learning. As well as several concrete projects, such as Comenius school project, school development consisted of networking at many levels. Along with the projects and networking, the school was able to apply the pedagogy of connection, by carrying out integrative and cross-disciplinary themes and using various learning and teaching methods. International cooperation was a natural part of the work. A figure of Aunt Green, the role model of the teacher researcher, was an innovation which resembled a change agent. The other role of the teacherresearcher as a coordinator, was important for her own professional development. According to the results the change process, which relied on sustainable school development, led the school along a road of positive renewals. It was not a series of projects but an ongoing process. The objectives of the international projects were accomplished to a great extent during the research period. According to the principles of action research, the main results were put forward in order to help others to develop their schools. Frictions and problems as well as positive experiences and rejecting dualities were seen as change forces. Keywords: education for sustainable development (ESD), sustainable school development, teacher professional development, integrating, pedagogy of connection, transformative learning

"It makes you think anything is possible”: Representing diversity in music theory pedagogy

This paper critiques a traditional approach to music theory pedagogy. It argues that music theory courses should draw on pedagogies that reflect the diversity and pluralism inherent in 21st century music making. It presents the findings of an action research project investigating the experiences of undergraduate students undertaking an innovative contemporary art music theory course. It describes the students’ struggle in coming to terms with a course that integrated composing, performing, listening and analysing coupled with what for many was their first exposure to the diversity of contemporary art music. The paper concludes with suggesting that the approach could be adopted more widely throughout music programs.

Enterprise education: Revisiting Whitehead to satisfy Gibbs

Purpose – This paper seeks to demonstrate that a truly learner-centred enterprise education programme can be developed within a traditional business school environment. Design/methodology/approach – This paper unites the broad teaching philosophy of Alfred Whitehead with that of Allan Gibbs’s enterprise specific teaching philosophies to consider the fitness of the recently developed hic et nunc enterprise framework. This is largely achieved by testing the framework for constructive alignment. Findings – It is argued that the hic et nunc framework is consistent with the philosophies of both Whitehead and Gibb. Further, the framework illustrates a process through which enterprise education programmes can be developed independently of any pressures to conform to more traditional pedagogy. Practical implications – Through careful consideration of the process of constructive alignment, an analytical approach to developing and/or refining an enterprise education program exists. Importantly, it represents an approach that is explicitly learner-centred, and therefore free from the constraints of the environment within which the programme is delivered. Originality/value – This paper brings to life the wonderful ideas of the great philosopher, Alfred Whitehead, combining them with the contemporary ideas of Allan Gibb. In doing so, the complementary nature of their thoughts helps to illustrate the minimal requirements of a learner-centred approach to enterprise education

Práticas colaborativas no ensino de funções: uma aplicação no Programa de Educação de Jovens e Adultos do município do Rio de Janeiro

Esse trabalho apresenta uma experiência com o Ensino Colaborativo (EC) no Programa de Educação de Jovens e Adultos em uma escola da rede municipal de ensino do Rio de Janeiro. Ele visa dar ferramentas ao docente que possibilitem o uso do Ensino Colaborativo, além de explicar e estruturar o uso dessa prática colaborativa no ensino de matemática. O trabalho mostra também um estudo comparativo entre duas turmas do Ensino de Jovens e Adultos de um colégio do munícipio do Rio de Janeiro, na qual o EC foi utilizado em apenas uma delas, e esse estudo, visa caracterizar as diferenças entre o EC e o ensino tradicional. O fato de ter desenvolvido esse estudo do EC no Ensino de Jovens e Adultos se deu pelo fato de ser uma modalidade de ensino cujo público, historicamente, apresenta algumas dificuldades no processo de aprendizagem e também por se tratar de uma modalidade de ensino na qual a diversidade de experiências se torna um diferencial para o desenvolvimento da prática colaborativa. As atividades propostas visam criar um ambiente propício para que a interação entre os alunos e entre professor e aluno(s) ocorra. Cada estudante deve ser capaz de confrontar ideias, dividir conhecimentos e desenvolver ou adquirir habilidades, ou seja, cada um deve buscar o seu desenvolvimento e também o de todos que estão a sua volta. Ao aliar a prática colaborativa com o ensino de funções, foi possível introduzir o conceito básico de função e mostrar aos discentes as diferentes formas de representar uma função e de que maneira o conceito de função está ligado a diversas áreas do conhecimento. Espera-se que com esse trabalho qualquer pessoa que deseje utilizar o Ensino Colaborativo, sinta-se encorajado e embasado para desenvolver tópicos do programa de Matemática utilizando essa prática pedagógica. É importante destacar que todas as estruturações sugeridas podem e devem ser adaptadas a cada realidade e às suas peculiaridades, pois além de ser uma prática que visa melhorar o processo de ensino aprendizagem, o EC pode ser usado como uma ferramenta de análise que permite a todos os indivíduos participantes ter um melhor entendimento da sociedade na qual estão inseridos

Avaliação de desempenho de plataformas de virtualização de redes.

O objetivo desta dissertação é avaliar o desempenho de ambientes virtuais de roteamento construídos sobre máquinas x86 e dispositivos de rede existentes na Internet atual. Entre as plataformas de virtualização mais utilizadas, deseja-se identificar quem melhor atende aos requisitos de um ambiente virtual de roteamento para permitir a programação do núcleo de redes de produção. As plataformas de virtualização Xen e KVM foram instaladas em servidores x86 modernos de grande capacidade, e comparadas quanto a eficiência, flexibilidade e capacidade de isolamento entre as redes, que são os requisitos para o bom desempenho de uma rede virtual. Os resultados obtidos nos testes mostram que, apesar de ser uma plataforma de virtualização completa, o KVM possui desempenho melhor que o do Xen no encaminhamento e roteamento de pacotes, quando o VIRTIO é utilizado. Além disso, apenas o Xen apresentou problemas de isolamento entre redes virtuais. Também avaliamos o efeito da arquitetura NUMA, muito comum em servidores x86 modernos, sobre o desempenho das VMs quando muita memória e núcleos de processamento são alocados nelas. A análise dos resultados mostra que o desempenho das operações de Entrada e Saída (E/S) de rede pode ser comprometido, caso as quantidades de memória e CPU virtuais alocadas para a VM não respeitem o tamanho dos nós NUMA existentes no hardware. Por último, estudamos o OpenFlow. Ele permite que redes sejam segmentadas em roteadores, comutadores e em máquinas x86 para que ambientes virtuais de roteamento com lógicas de encaminhamento diferentes possam ser criados. Verificamos que ao ser instalado com o Xen e com o KVM, ele possibilita a migração de redes virtuais entre diferentes nós físicos, sem que ocorram interrupções nos fluxos de dados, além de permitir que o desempenho do encaminhamento de pacotes nas redes virtuais criadas seja aumentado. Assim, foi possível programar o núcleo da rede para implementar alternativas ao protocolo IP.

Interpersonal Aspects of Thinking Skills in an Intercultural Language Learning Context

Asking and answering certain types of questions are thought to develop thinking skills in all types of classrooms. Previous research has demonstrated that asking higher order questions and answering with elaborated responses are associated with high achievement in first, second, and foreign language contexts. Typically more attention is paid to question frequency or achievements inferred from individual performances than to the dialogues in which asking and answering occurs. This paper argues for a focus on the construction of responses in interaction as an alternative to the investigation of questions, effects of training or individual measurements of performance. Drawing on interactional data from an adult English as a Second Language classroom, it is argued that constructing an answer to a critical question appears to be a highly collaborative and evaluative affair. The thinking skills literature suggests that responding to higher order questions is an individual higher cognitive function, however it is argued in this paper that in attempting to construct evaluative answers language learners are involved not only in a cognitive task, which may or may not be helpful to language learning, but also in a complex social task in which perspectives need to be negotiated, stances taken and identities navigated. It is suggested that higher order thinking cannot be separated from the social and cultural knowledge through which it is brought into being. It is argued that any implementation of thinking skills in an English language teaching context ought to consider interpersonal and social aspects, particularly in intercultural settings.

Collaborative practice:a strategy to improve the relevance of health services research.

Health services research has emerged as a tool for decision makers to make services more effective and efficient. While its value as a basis for decision making is well established, the incorporation of such evidence into decision making remains inconsistent. To this end, strengthening collaborative relationships between researchers and healthcare decision makers has been identified as a significant strategy for putting research evidence into practice.

Analysis of Dependence Tracking Algorithms for Task Dataflow Execution

Processor architectures has taken a turn towards many-core processors, which integrate multiple processing cores on a single chip to increase overall performance, and there are no signs that this trend will stop in the near future. Many-core processors are harder to program than multi-core and single-core processors due to the need of writing parallel or concurrent programs with high degrees of parallelism. Moreover, many-cores have to operate in a mode of strong scaling because of memory bandwidth constraints. In strong scaling increasingly finer-grain parallelism must be extracted in order to keep all processing cores busy.

Task dataflow programming models have a high potential to simplify parallel program- ming because they alleviate the programmer from identifying precisely all inter-task de- pendences when writing programs. Instead, the task dataflow runtime system detects and enforces inter-task dependences during execution based on the description of memory each task accesses. The runtime constructs a task dataflow graph that captures all tasks and their dependences. Tasks are scheduled to execute in parallel taking into account dependences specified in the task graph.

Several papers report important overheads for task dataflow systems, which severely limits the scalability and usability of such systems. In this paper we study efficient schemes to manage task graphs and analyze their scalability. We assume a programming model that supports input, output and in/out annotations on task arguments, as well as commutative in/out and reductions. We analyze the structure of task graphs and identify versions and generations as key concepts for efficient management of task graphs. Then, we present three schemes to manage task graphs building on graph representations, hypergraphs and lists. We also consider a fourth edge-less scheme that synchronizes tasks using integers. Analysis using micro-benchmarks shows that the graph representation is not always scalable and that the edge-less scheme introduces least overhead in nearly all situations.

Robotics and Development of Intellectual Abilities in Children

It is necessary to transform the educative experiences into the classrooms so that they favor the development of intellectual abilities of children and teenagers. We must take advantage of the new opportunities that offer information technologies to organize learning environments which they favor those experiences. We considered that to arm and to program robots, of the type of LEGO Mind Storms or the so called “crickets”, developed by M. Resnik from MIT, like means so that they children them and young people live experiences that favor the development of their intellectual abilities, is a powerful alternative to the traditional educative systems. They are these three tasks those that require a reflective work from pedagogy and epistemology urgently. Robotics could become in the proper instrument for the development of intelligence because it works like a mirror for the intellectual processes of each individual, its abilities like epistemologist and, therefore, is useful to favor those processes in the classroom.

Social development of primary aged children through a movement education program

Unique in Canada, is a university based movement program offered to children aged 1-12 which is diverse and inclusive in its design to foster healthy physical, cognitive, affective and social development. The purpose of this study is to investigate how children's involvement in a weekly movement education program influences their social development. The primary-aged children involved in this research are participants in the university based Saturday morning program, The Children's Movement Program (CMP), in which creative dance, educational gymnastics and developmental games are employed to enhance optimal development. The 15 participants were systematically observed for 8 weeks as they naturally engaged in the program's activities. Interviews were conducted with both children and their caregivers throughout the duration of the program. Particular attention was paid to the perceptions of caregivers regarding the advantages of a program based upon principles of movement education. Results indicate that participation in the program increases children's opportunity to interact socially and address ways in which program content, pedagogy and context encourage social development. A figure was developed with these components to assist teachers in creating inclusive and meaningful movement experiences. 'Content' is referred to as the material to be learned or the desired outcome for the learner. 'Pedagogy' refers to the process in which the student will engage and 'Context' refers to the environment in which the experience occurs (eg. skating rink with playground balls). It is recommended that each is thoroughly addressed individually for its potential in lesson design.
