Viscoplastic behaviour of porous bronzes and irons

An experimental investigation is presented for the viscoplastic behaviour of porous metals. The interest is in the influence of porosity on the deformation behaviour of such materials under loading at various strain rates. Material samples of bronze with 10% tin and pure iron were fabricated by powder metallurgy technology with porosity ranging from 10 to 40%. The samples were then subjected to a large uniaxial compression under both quasi-static and dynamic loading with the maximum strain rate at 10 s−1. The materials show behaviour in an approximately bi-linear nature for strain up to 0.4. The data will be used to develop simple phenomenological constitutive models, which incorporate the volume fraction as a control factor.

Re-presenting teachers’ experiences of using game based approaches through poetic transcription

This paper provides an overview of poetic transcription and how I used it to re-present physical education teachers’ experiences of teaching games using a game based approach (GBA). Composite narratives derived from a study exploring teachers’ experiences of GBA teaching provided the initial storying of experience with three separate teacher capacities for experience identified; that of a Learner, a Collaborator, and a Catalyst. These narratives were then re-storied as found poems. Discussion within this paper comments on the reflexive action I engaged with to transform interview transcripts into poetic form with specific comment offered as to my rationale for use of poetic transcription as well as the process I undertook to re-see teachers’ experiences of GBA experience. Comment stemming from a comparison of poems is also offered along with what experimentation with poetic transcription enabled me to “do” with my understanding of the experience of GBA teaching.

Recent trends in research literature on game-based approaches to teaching and coaching games

As suggested by Curry and Light in chapter nine, the expanding output of research on games-based approaches (GBAs) over the past decade has not been reflected in expanding utilisation of GBAs in school-based physical education programmes and club-based sport coaching environments. Reasons for this lack of ‘uptake’ are varied and range from a lack of exposure to effective GBA professional development opportunities to the prolonged acceptance of a performative culture often embedded within physical education and youth sport programmes (Harvey and Jarrett, 2012; Dismore and Bailey, 2010). The literature on games teaching published since Oslin and Mitchell’s review of GBAs in 2006 continues to acknowledge the many benefits of using GBAs, but also acknowledges, and to a lesser extent addresses, the key challenges associated with the employment of learner-centred and GBA pedagogies. This chapter provides an overview of post-2005 research trends in the GBA literature to identify and discuss the prominent themes that arose from this meta-analysis.

The role of the libero in volleyball as a paradoxical influence on the game: logical debate and the proposal for a rule change

The purpose of this paper is to bring into focus philosophical and logical concerns relating to specific rules that govern the role of the libero in volleyball. The authors contest that the introduction of the position of the libero in volleyball may have actually undermined the continuing logic of the rules of the game. In addressing these questions the authors offer theoretically based rule-change proposals for the sport of volleyball that could be used to inform future training methods or development programmes at both the participatory and elite levels. Discussion may also inform the development of new tools of analysis (e.g. computer software) or the creation of a new breadth of match simulation resources to enhance athlete performance. These tools and devices could then be presented to volleyball coaches in an effort to resolve the issues that have come to light and further inform the philosophical and logical debates about the role of the libero in volleyball.

A review of the game-centred approaches to teaching and coaching literature since 2006

Background: In 2006, Oslin and Mitchell published a review of the game-centred approaches (GCAs) to teaching and coaching literature highlighting a number of core concepts thought to provide justification for the use of GCAs including (a) its potential to enhance participant motivation, (b) potential for tactical transfer, and (c) development of decision-making skills and effective decision-makers. Oslin and Mitchell also suggested recommendations for future GCA research.Purpose: The purpose of this paper was threefold: (a) to present a review of Anglophone research into GCAs building on the previous review of Oslin and Mitchell published in 2006; (b) to identify new trends in research since 2006; and (c) to investigate the extent to which the initial suggestions and future research directions suggested by Oslin and Mitchell have been addressed.Data collection: GCA literature since 2006 was searched systematically using a three-phase approach. Phase 1 included initial searches of the EBSCO database using terms associated with GCAs and their acronyms (e.g. TGfU (teaching games for understanding), GS (Game Sense), etc.). Phase 2 expanded the search adopting more generic terms from keywords located in the recent literature (e.g. teaching games, tactical development, game performance, etc.). Multiple searches through the EBSCO database were conducted, whereby key terms were cross-referenced until a saturation point was reached. Phase 3 involved removing those publications that were not empirical, peer reviewed, intervention studies or published in English.Findings: Forty-four studies on GCA implementation were identified and the methodological and substantive nature of these studies was examined. The review noted two positive trends: (a) the expansion of research which included the growth of research on GCAs in Europe and Southeast Asia and (b) an increased amount of research in the affective domain. The review found, however, that a number of key challenges remain within GCA research, which include (a) the need for improved articulation of GCA verification procedures; (b) further assessment of tactical awareness development; (c) extended inquiry about GCAs in coaching contexts; (d) more research into ‘newer’ GCAs (i.e. PP (play practice), IGCM (invasion game competence model) and TDLM (tactical decision learning model)); (e) use of longitudinal research designs; (f) inadequate length of GCA induction and training for teachers and coaches, and (g) examination of GCAs in terms of fitness and special populations.Conclusions: GCA pedagogies are of significant importance as they have the potential to promote change within current adult-centric cultures of youth sport and encourage engagement in physical activity over the life course. To meet these needs, it is recommended that GCA research undergo continued expansion with the use of research designs and data collection techniques that aid the examination of different philosophical understandings of GCAs (e.g. ethnographic, phenomenological and psycho-phenomenological). These are paramount to the exploration of ‘who the individual is’ and ‘how the learner is motivated to continue to participate’ and further permit the in-depth, contextual and ecological analysis of GCA interventions that Oslin and Mitchell recommended in their previous review.

Teaching games for understanding (TGFU) as a positive and versatile approach to teaching adapted games

This paper presents a small scale research project that focused on pre-service physical education (PE)teachers’ and sports coaches’ considerations of using Teaching Games for Understanding (TGfU) to teachgames. A research design akin to action research was adopted whereby pre-service PE teachers and sportscoaches (n = 72) completed a one-off 90 minute introduction to wheelchair rugby league utilising a TGfUapproach. Data were generated through end of session whole-class reflections, semi-structured individualinterviews undertaken (n = 3), and post session first-author/primary practitioner reflections. Data analysiswas conducted via inductive coding procedures and revealed three themes: 1) TGfU as a positive pedagogy;2) TGfU as a versatile approach, and 3) significance of content within a PE Teacher Education programme.

Undergraduate sports students' perceptions of a change to game sense pedagogy

This paper contributes to research in the scholarship of teaching by reporting on undergraduate sports students perceptions of their own learning when exposed to a Game Sense learning approach and reflections on my experience of teaching it. A multiple methods approach was utilised to gather data from a four-week games component of a 10-week unit of study with all participants (n = 20; aged 18-21) in their first year of a three-year sports-related undergraduate degree. The games classification system was used to plan session content over the four weeks with each week focusing on a different games classification. Data were organised and coded via inductive coding procedures with analysis conducted concurrently to identify three prominent themes: 1) positive experiences of competition and game play, 2) the range of cognitive and emotional learning opportunities provided by Game Sense pedagogy facilitated improved student engagement and learning, and 3) the challenge of effective teacher questioning to stimulate game play knowledge construction.

Using elicitation interview within a phenomenographic framework : developing the breadth of research designs associated with game based approaches

This paper describes how elicitation interview technique was used within a phenomenographic research design to explore physical education teachers’ experiences of teaching games using a Game Based Approach (GBA). Participants taught in one of two different international contexts, Australia or England, and all had some experience of using a GBA to teach games. The focus of the paper is the presentation and discussion of the unique research design used to generate understanding about GBA teaching experiences as well as extending the examination of GBAs from different philosophical viewpoints. Authors’ reflections on the utilised research design are presented with concluding discussion identifying further research opportunities relating to GBAs in teaching and coaching contexts.

Similar, but not the same: comparing the game based approaches of TGfU and game sense

The development and use of game based approaches (GBAs) across a range of global teaching and coaching settings has expanded significantly over the last two decades. And with each GBA underpinned by similar theories of learning, distinctions between each approach can often be blurred. Arguably, this can lead to teachers' and coaches' blended conceptualisations of different pedagogical approaches. Thus, although similar there is a need for teachers and coaches to recognise that not all GBAs are the same with each model or approach chosen impacting significantly upon learner experiences. Through analysis of literature and presentation of teaching/coaching lesson/session outlines, this paper presents similarities and differences of two game based instructional pedagogies - TGfU and Game Sense - and discusses the need for teachers and coaches to recognise and respond to the contextual differences of each when considering their use.

‘What else can I do?’ Radical suggestions to help physical education teachers successfully implement a game based approach to teach games

As with any new relationship when teachers implement a different or unfamiliar pedagogical approach into the classroom it is often accompanied by a period of unaccustomed behaviour; such as a reluctance for teachers to commit or a wariness from learners to invest or reveal. The challenges that teachers and learners face in the initial stages of this new relationship, if overcome, can be the mainstays of a mutually beneficial learning experience. Yet, as many teachers have experienced, the reverse of this is also true. Failure to adequately invest, plan and commit to the introduction of a new pedagogical approach can bring with it long term consequences that include an unwillingness to ever start a new relationship again.
