Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science. 相似文献

Australia has declared its ambition to be within the ‘top five’ in the Programme for International Student Assessment (PISA) by 2025. So serious is it about this ambition, that the Australian Government has incorporated it into the Australian Education Act, 2013. Given this focus on PISA results and rankings, we go beyond average scores to take a close look at Australia's performance in PISA, examining rankings by different geographical units, by item content and by test completion. Based on this analysis and using data from interviews with measurement and policy experts, we show how uninformative and even misleading the ‘average performance scores’, on which the rankings are based, can be. We explore how a more nuanced understanding would point to quite different policy actions. After considering the PISA data and Australia's ‘top five’ ambition closely, we argue that neither the rankings nor such ambitions should be given much credence. 相似文献

ABSTRACTInternational large-scale assessments and comparisons (ILSAs) in education have become significant policy phenomena. How a country fares in these assessments has come to signify not only how a nation’s education system is performing, but also its future prospects in a global economic ‘race’. These assessments provoke passionate arguments at specialist conferences and in scholarly journals and they are just as passionately debated in the media. Within academe, ILSAs are researched by sociologists and psychometricians, policy experts and statisticians. This multidisciplinary, multi-voice discussion has not always served to highlight the complexity of the issues involved. Instead, discussions across various groups of actors have often led to a polarisation of views and a hardening of stances. Large-scale comparisons have deeply divided academic opinion with regard to their validity, usefulness and use. The divergence in ontological commitments, methodologies and paradigms of research makes discussions among one set of scholars almost incomprehensible to another. New theories, concepts and vocabularies are urgently required to engage productively with this important phenomenon. Borrowing concepts from Science and Technology Studies (STS) and the history and sociology of numbers, I argue that understanding such comparative exercises as socio-technical assemblages would move the critique of large-scale comparisons in education in more productive directions. 相似文献

The conjunction of equity and market logics in contemporary education has created new and different conditions of possibility for equity, both as conceived in policy discourses and as a related set of educational practices. In this editorial introduction, we examine how equity is being drawn into new policy assemblages and how, in the context of marketisation, equity is evolving and being enacted in new ways across education sectors. Different conceptions of equity are considered, including the increasingly influential human capital perspective promoted by the Organisation for Economic Cooperation and Development (OECD). We argue that, separate from critiques of neoliberalism and its deleterious effects on equity in education, it is necessary to analyse carefully the increasing rationalisation of equity agendas in economic terms, the associated effects on education governance and policy-making, as well as on the work of educational institutions and educators. Providing an overview of the contributions to this Special Issue, we direct particular attention to the multiple, complex and often contradictory effects of the current education reform agenda in Australia, which has prioritised equity objectives and intensified performance measurement, comparison and accountability as means to drive educational improvement and reduce disadvantage. 相似文献

The influence of television news over public opinion is tracedto the ‘accessibility bias’ in processing information.In general, the argument stipulates that information that canbe more easily retrieved from memory tends to dominate judgments,opinions and decisions. In the area of public affairs, moreaccessible information is information that is more frequentlyof more recently conveyed by the media. Four different manifestationsor the accessibility bias in public opinion are described includingthe effects of news coverage on issue salience, evaluationsof presidential perfomance, attributions of issue responsibility,and voting choices. 相似文献

The drag flick is the preferred method of scoring during a penalty corner in field hockey. Performing the drag flick requires a combination of strength, coordination and timing, which may increase susceptibility to injuries. However, injury prevalence in drag flickers has not previously been investigated. Therefore, this study compared the injury prevalence and severity of lower limb and lower back injuries between drag flickers and non-drag flickers in field hockey. A total of 432 local, national and international adult field hockey players (242 males, 188 females) completed an online questionnaire to retrospectively determine the 3-month prevalence and severity of ankle, knee, hip and lower back injuries. Of this group, 140 self-identified as drag flickers and 292 as non-drag flickers. The results showed that drag flickers had significantly higher prevalence of hip (OR: 1.541; 95% CI: 1.014, 2.343) and lower back injury (OR: 1.564; 95% CI: 1.034, 2.365) compared to non-drag flickers. No significant differences were observed between drag flickers and non-drag flickers in injury prevalence at the ankle and knee. There were no significant between-group differences in injury severity scores. Overall, the prevalence of hip and lower back injuries was significantly higher in drag flickers compared to non-drag flickers. 相似文献

ABSTRACT While the use of numbers in governance has a long history, the kinds of numbers we now produce enable a range of new possibilities for monitoring, regulation and policy decision-making. Global policy actors are now calling for a steep increase in investment in education data. The growing trust in numbers has been critiqued by education policy scholars and social scientists, who have pointed to the reductionist nature of numbers and the dangerous decontextualisation of information which are leading to detrimental policies. The entry of big data poses even more complex epistemological and ontological challenges, many of which we do not fully understand as yet. This paper acknowledges these challenges, and at the same time speculates that big data might afford unique possibilities for new relational theories that may lead to better policy decision-making. 相似文献
