Investigating the pedagogical process in physical education teacher education

The study investigated two main questions: the first focused on the factors that enabled and constrained student teachers\u27 engagement of a socially critical pedagogy in physical education teacher education (PETE); the second centered on gaining insight into the usefulness of knowledgeability as a concept for analysing student teachers engagement of a socially critical pedagogy. At the time of writing this thesis empirical analyses of socially critical pedagogies in physical education were rare in the educational literature. The study provided an alternative way of analysing student teachers’ engagement of a socially critical pedagogy in PETE. Alternative in that it avoided recycling and reproducing the dualism between agency and structure (Aronowitz and Giroux, 1985) that is prevalent in much of the physical education literature. Conversational interviews were conducted with four student teachers and their teacher educators throughout the duration of a one-semester PETE unit in an Australian university. Observations were made of the lecture and practical sessions and a document analysis was conducted of all unit learning resources. The analytical frame used in the study was structuration theory (Giddens, 1979, 1984). This framework was useful because it gave primacy to the duality of structure which recognised ‘the structural properties of social systems are both the medium and outcome of practices that constitute those systems’ (Giddens, 1979, p.69). The pedagogical intentions of the teacher educator co-ordinating the PETE unit were to change the orientations of the student teachers towards primary school physical education by encouraging them to adopt different ‘lenses’ through which to examine pedagogical practices. These ‘lenses’ highlighted the questions central to those with socio-critical intentions, eg. power, social injustice and diversity. Data generated from conversations with, and observations of, the student teachers, indicated that the actualisation of the teacher educator\u27s intentions were somewhat limited. Despite this, adopting structuration theory as the explanatory framework for the study proved generative at a number of levels. Broadly, structuration theory was useful because it highlighted the way that student teachers\u27 engagement with a socially critical pedagogy is contingent upon particular (idiosyncratic) dialectics of agency and structure. Using the duality of structure as an analytical tool illustrated the way student teachers\u27 were influenced by structural factors as well as the way these structural factors were in turn constituted by the action of the student teachers. Also, by utilising structuration theory as an explanatory framework, the concept of knowledgeability was identified as a useful concept for analysing student teachers\u27 engagement with a socially critical pedagogy in PETE. What is more, the study highlighted the reflexivity of the self and social knowledge, both characteristics of late modernity, as being integral to the way the student teachers engaged with the socially critical pedagogy of EAE400. Not only did the study highlight the reflexivity of the self but it also provided insight into the reflexivity of social knowledge. Much of the socially critical work in physical education implicitly adopts a linear approach to change. Given the findings of the study it might be useful for future developments to consider change as circular. The thesis concludes by suggesting that given the reflexivity of social knowledge, socially critical perspectives might be more readily engaged if the PETE content was incorporated into student teachers existing knowledge frameworks rather than viewed as a replacement for such frameworks

Intersectional Border(ing)s

This special issue of Political Geography marks a contribution to the fields of feminist geopolitics and border studies by bringing together a series of papers, which use approaches based on Yuval-Davis’ ‘situated intersectionality’ (2015) to explore everyday bordering within and without contemporary Europe. The special issue is comprised of work undertaken by colleagues from across Europe and beyond as part of work package 9 ‘Borders, Intersectionality and the Everyday’ of the EUBorderscapes project (2012-2016). We term our approach to studying borders, borderscapes and bordering processes as ‘situated intersectional bordering’. The main contribution of this approach is that borders and borderings are understood as dialogical constructs and that if we are to understand how they are being made and re-made we must attempt to explore them through the situated gazes of differentially positioned social actors. We therefore suggest a holistic approach to understanding border(ing)s, which is embedded in everyday life. Through the study of the multi-layered complexities of everyday borderings we can ‘approach the truth’ (Hill-Collins, 1990)

Sexual Nature? (Re)presenting Sexuality and Science in the Museum

PublishedJournal Article© 2016 Process Press.The past 15 years have seen dramatic changes in social norms around sex and sexuality in the UK and worldwide. In 2011, the London Natural History Museum (NHM) contributed to these debates by opening the temporary exhibition Sexual Nature, which aimed to provide ‘a candid exploration of sex in the natural world’ whilst also drawing in an under-represented audience of young adults. Sexual Nature provides an opportunity to explore Macdonald's ‘politics of display’ in the mutual construction of (public) scientific knowledge, society and sexuality, at a time of intense contestation over sexual norms. Whilst Sexual Nature both reflected and contributed to major reframings of sexuality and what science can say about it, the assumption that it would be possible to present this topic as morally neutral, reliable and uncontested, in line with traditions of public science, proved to be problematic. The language of the exhibition moved back and forth between human/animal similarity and difference, and between scientific and cultural tropes as the NHM tried to maintain epistemic authority whilst also negotiating the moral boundaries of acceptable sexual behaviour. The topic of sex pushed the museum far beyond its usual expertise in the natural sciences towards the unfamiliar territory of the social and human, resulting in an ad hoc search for, and negotiation with, alternative sources of expertise. Boon et al.’s co-curation approach to exhibition building has the potential to extend the NHM's audience-driven strategy, whilst also producing a more coherent and nuanced exhibition about the science of sex

Making mentoring work: The need for rewiring epistemology

To help produce expert coaches at both participation and performance levels, a number of governing bodies have established coach mentoring systems. In light of the limited literature on coach mentoring, as well as the risks of superficial treatment by coach education systems, this paper therefore critically discusses the role of the mentor in coach development, the nature of the mentor-mentee relationship and, most specifically, how expertise in the mentee may best be developed. If mentors are to be effective in developing expert coaches then we consequently argue that a focus on personal epistemology is required. On this basis, we present a framework that conceptualizes mentee development on this level through a step by step progression, rather than unrealistic and unachievable leap toward expertise. Finally, we consider the resulting implications for practice and research with respect to one-on-one mentoring, communities of practice, and formal coach education

The formation of marine kin structure : effects of dispersal, larval cohesion, and variable reproductive success

The definitive version was published in Ecology 99 (2018): 2374-2384, doi:10.1002/ecy.2480.The spatial distribution of relatives has profound e ects on kin interactions, inbreeding, and inclusive tness. Yet, in the marine environment, the processes that generate patterns of kin structure remain understudied because larval dispersal on ocean currents was historically assumed to disrupt kin associations. Recent genetic evidence of co-occurring siblings challenges this assumption and raises the intriguing question of how siblings are found together after a (potentially) disruptive larval phase. Here, we develop individual based models to explore how stochastic processes operating at the individual level a ect expected kinship at equilibrium. Speci cally, we predict how limited dispersal, sibling cohesion, and variability in reproductive success di erentially a ect patterns of kin structure. All three mechanisms increase mean kinship within populations, but their spatial e ects are markedly di erent. We nd that: (1) when dispersal is limited, kinship declines monotonically as a function of the distance between individuals; (2) when siblings disperse cohesively, kinship increases within a site relative to between sites; and (3) when reproductive success varies, kinship increases equally at all distances. The di erential e ects of these processes therefore only become apparent when individuals are sampled at multiple spatial scales. Notably, our models suggest that aggregative larval behaviors, such as sibling cohesion, are not necessary to explain documented levels of relatedness within marine populations. Together, these ndings establish a theoretical framework for disentangling the drivers of marine kin structure.CCD was supported by a Weston Howland Jr. Postdoctoral Scholarship from WHOI.

On the amino acids of sponges

The distribution of amino acids in 14 sponges was surveyed qualitatively by paper chromatography. Dried acetone-extracted sponge material was treated with 95% alcohol to remove soluble amino acids and peptides. From two sponges this material consisted largely of peptides, five of which were hydrolyzed and examined. From the present data it appears doubtful that any significant correlation exists between the amino acid distribution in sponges and the biological classification of these organisms

Patterns, causes, and consequences of marine larval dispersal

Quantifying the probability of larval exchange among marine populations is key to predicting local population dynamics and optimizing networks of marine protected areas. The pattern of connectivity among populations can be described by the measurement of a dispersal kernel. However, a statistically robust, empirical dispersal kernel has been lacking for any marine species. Here, we use genetic parentage analysis to quantify a dispersal kernel for the reef fish Elacatinus lori, demonstrating that dispersal declines exponentially with distance. The spatial scale of dispersal is an order of magnitude less than previous estimates—the median dispersal distance is just 1.7 km and no dispersal events exceed 16.4 km despite intensive sampling out to 30 km from source. Overlaid on this strong pattern is subtle spatial variation, but neither pelagic larval duration nor direction is associated with the probability of successful dispersal. Given the strong relationship between distance and dispersal, we show that distance-driven logistic models have strong power to predict dispersal probabilities. Moreover, connectivity matrices generated from these models are congruent with empirical estimates of spatial genetic structure, suggesting that the pattern of dispersal we uncovered reflects long-term patterns of gene flow. These results challenge assumptions regarding the spatial scale and presumed predictors of marine population connectivity. We conclude that if marine reserve networks aim to connect whole communities of fishes and conserve biodiversity broadly, then reserves that are close in space (<10 km) will accommodate those members of the community that are short-distance dispersers.We thank Diana Acosta, Alben David, Kevin David, Alissa Rickborn, and Derek Scolaro for assistance with field work; Eliana Bondra for assistance with molecular work; and Peter Carlson for assistance with otolith work.
