Rethinking resources and hybridity     

Allison J. Gonsalves  Gale Seiler  Dana E. Salter 《Cultural Studies of Science Education》2011,6(2):389-399

This review explores Alfred Schademan??s ??What does playing cards have to do with science? A resource-rich view of African American young men?? by examining how he uses two key concepts??hybridity and resources??to propose an approach to science education that counters enduring deficit notions associated with this population. Our response to Schademan??s work expands upon his definition of hybridity and its purpose in the science classroom and highlights the tensions inherent in the appropriation of student resources in classroom spaces. This conversation points also to the need for research analyses and pedagogical approaches that simultaneously valorize student resources, allow student opportunities to learn the dominant codes, and provide teacher and student opportunities to transform them. Carol Lee??s notion of ??cultural modeling?? is discussed as a possible framing device to facilitate this kind of research.  相似文献   

A reconceptualisation of ‘knowing Asia’ in Australian education     

Peta Salter 《Discourse: Studies in the Cultural Politics of Education》2015,36(6):781-794

Since 1969, over 60 Australian government and non-government policies, documents, committees, working parties and organisations have explored the need to ‘know Asia’. In schools, this engagement is conceptualised as ‘Asia literacy’ and disseminated in the emerging Australian Curriculum through the cross-curriculum priority ‘Asia and Australia's engagement with Asia’. However, ‘Asia literacy’ often struggles for purchase in Australian education. I argue that finding traction requires disruption of the dominant discourse of ‘Asia’ as a unitary construct and questioning what constitutes ‘Asia’. This article explores how discourse can be reconceptualised to open up space for schools to engage with ‘knowing Asia’.  相似文献   

Proceeding carefully: assisted human reproduction policy in Canada     

Jones M  Salter B 《Public understanding of science (Bristol, England)》2010,19(4):420-434

The Canadian Act Respecting Assisted Human Reproduction and Related Research (AHR Act), which came into effect in 2004, was the culmination of fifteen years of policy development in this often controversial field. Drawing from a series of semi-structured elite interviews and extensive documentary research, we examine the path to policy for the AHR Act. We identified several influences on the Act's development, including: (1) feminist-informed activism which found a balance between rejecting the medical model of reproduction and instituting protections against the commodifying potential of reproductive technologies; (2) Canada's proximity to the United States (and its contrasting structures and stances); (3) the role of professional elites in supporting or resisting the proposed regulations; and (4) the tensions between federal and provincial jurisdiction in the Canadian federalist state. The path to this outcome provides an illuminating study of the tensions between internal and external pressures in the policy process.  相似文献   

Maturity-associated considerations for training load,injury risk,and physical performance in youth soccer: One size does not fit all     

Chris Towlson  Jamie Salter  Jack D. Ade  Kevin Enright  Liam D. Harper  Richard M. Page  James J. Malone 《运动与健康科学(英文)》2021,10(4):403-412

Biological maturation can be defined as the timing and tempo of progress to achieving a mature state. The estimation of age of peak height velocity (PHV) or percentage of final estimated adult stature attainment (%EASA) is typically used to inform the training process in young athletes. In youth soccer, maturity-related changes in anthropometric and physical fitness characteristics are diverse among individuals, particularly around PHV. During this time, players are also at an increased risk of sustaining an overuse or growth-related injury. As a result, the implementation of training interventions can be challenging. The purpose of this review was to (1) highlight and discuss many of the methods that can be used to estimate maturation in the applied setting and (2) discuss the implications of manipulating training load around PHV on physical development and injury risk. We have provided key stakeholders with a practical online tool for estimating player maturation status (^{Supplementary Maturity Estimation Tools}). Whilst estimating maturity using predictive equations is useful in guiding the training process, practitioners should be aware of its limitations. To increase the accuracy and usefulness of data, it is also vital that sports scientists implement reliable testing protocols at predetermined time-points.  相似文献   

The associations between fast bowling technique and ball release speed: a pilot study of the within-bowler and between-bowler approaches     

Salter CW  Sinclair PJ  Portus MR 《Journal of sports sciences》2007,25(11):1279-1285

The inability of the between-bowlers methodology to control parameters external to technique could lead to erroneous significant and non-significant associations being reported between fast-bowling technique and ball release speed. Using Pearson's product - moment correlation, we first examined the effectiveness of a within-bowler methodology to identify associations between technique and ball release speed of an elite semi-open fast bowler over 20 deliveries. These results were compared with associations identified from a between-bowlers methodology in which 20 single-performance trials bowled by elite fast bowlers adopting a semi-open shoulder alignment were collated. Sufficient variation was observed in within-bowler ball release speed to allow f relationships to be identified between technique and ball release speed. Although greater variation in bowling technique parameters was observed in the between-bowlers methodology, no associations were identified between technique and ball release speed. Multiple stepwise regression analysis showed that 87.5% of the within-bowler variation in ball release speed can be attributed to run-up velocity, angular velocity of the bowling arm, vertical velocity of the non-bowling arm, and stride length. The within-bowler methodology provided significant detailed information about the individual bowler that the between-bowlers methodology overlooked, forming the basis of a performance enhancement programme. It is recommended that within-bowler methodology be used in future investigation of technique relationships.  相似文献   

A biomechanical comparison of dominant and non-dominant arm throws for speed and accuracy     

Sachlikidis A  Salter C 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(3):334-344

Training a non-dominant limb may increase a competitor's ability to perform with either side of his or her body and confer an advantage over competitors that use one side of the body exclusively. The aim of this study was to determine the kinematic differences between dominant and non-dominant arm throwing techniques for speed and accuracy in Under-17 and Under-19 high-performance cricketers. Seven participants performed ten throws for each arm (dominant/non-dominant) and condition (speed/accuracy) at a target positioned 10 m in front of them. Three-dimensional kinematic variables were measured using a Vicon motion analysis system. Digital footage was used to calculate stride data, ball speed, and record target accuracy. Data were analysed using repeated-measures analysis of variance and chi-squared tests. The non-dominant arm throws had significantly lower maximum lead knee lift, did not extend the lead knee in the arm acceleration phase, had significantly less elbow flexion before extension, had significantly less shoulder external rotation at the start of the arm acceleration phase, did not have a delay between the initiation of pelvic and upper torso internal rotation, and displayed a less than optimal coordination pattern. A speed-accuracy trade-off existed for the dominant arm throws. No trade-off was identified for the non-dominant arm throws. Through an enhanced understanding of how throwing technique varies between dominant and non-dominant arms, an opportunity exists for a performance-enhancing programme to be implemented so that ambidexterity of the throwing skill can be improved.  相似文献   

The External Pressures on the Internal Governance of Universities     

Brian Salter  & Ted Tapper 《Higher Education Quarterly》2002,56(3):245-256

Governance is a means for realising institutional goals and in an ideal world should enable the institution to respond to the demands of the political environment by regulating its internal affairs accordingly. In the case of universities, not only is that environment increasingly differentiated but so also is the ability of universities to access it. Changes in state funding arrangements, accountability mechanisms, the contribution of the private sector, and the public definition of university education have placed numerous and varied pressures on institutions. Yet there is a studied reluctance by institutions to accept that their ability to respond to these pressures is equally variable, that they should tailor their ambitions to their capacities, and that their internal governance should be adapted using the principle of fitness for purpose. In the main, this is because the dominant ideological themes of higher education do not support the idea of distinct university functions of equal status. Rather, they encourage the erroneous belief that all universities are homogeneous in their functions – or, at least, that all have the potential to be homogeneous.  相似文献   

Decentring the ‘places’ of citizens in national curriculum: the Australian history curriculum     

Kelsey Halbert  Peta Salter 《Curriculum Journal》2019,30(1):8-23

There is debate internationally about the production of curriculum texts and the epistemologies underpinning the knowledge legitimated in national curricula. National History curricula in particular are a source of contention bounded by calls for coherent and unifying national narratives that are inclusive and reflect the complexity of the discipline and historical consciousness of the nation to which they are bound. This paper uses critical spatial theory to highlight the ‘spaces’ and ‘places’ of the Australian Curriculum History (years 7–10) which organise and disorganise representations of identities in and out of the centre of the national narrative. Interrogating the impact of these representations within purported inclusive and cohesive national narratives draws attention to the notions of belonging presented to Australian citizens. We argue that resistance to normative national narratives and colonial legacies presented with place-based identities can reinhabit the curriculum. This reinhabiting and decentring seeks to engage History students with alternative perspectives and articulations to the national narrative, and foster meaningful connections to place and citizenship. Finally, critical place-based education approaches invite an embodied local/global citizen through local and marginalised knowledges.  相似文献

Higher Education as a System: The English Experience     

Ourania Filippakou  Brian Salter  Ted Tapper 《Higher Education Quarterly》2012,66(1):106-122

With particular, although not exclusive, reference to England, this article explores the appropriateness of describing higher education as a system. It has two main purposes: to explore the grounds for labelling English higher education as a system and to argue that, because this is no longer an appropriate label, a different conceptualisation is required. The central argument is that the structure of higher education is formed through the interaction of the state, market and higher education institutions and is, therefore, a shifting political construct. Furthermore, it will be hypothesised that the English (indeed, the British) model of higher education is better described as an increasingly internally differentiated network of sectors rather than as a system.  相似文献
