The Impact of Alternative Routes on the Work and Identities of Teacher Educators: The English Case
We are all teacher educators now: understanding school-based teacher educators in times of change in England
Within the context of the European Commissionâs recent policy gaze on teacher education (European Commission, Improving teacher quality: The EU agenda â lifelong learning: policies and programme. Brussels, April 2010, EAC.B.2. D (2010) PSH, 2010; European Commission, Supporting teacher educators for better learning outcomes. European Commission, Brussels, 2013; European Commission, Strengthening teaching in Europe: new evidence from teachers compiled by Eurydice and CRELL, June 2015. Available from: http://ec.europa.eu/education/library/policy/teaching-profession-practices_en.pdf, 2015), this chapter contributes to an improved understanding of the hybrid, poly-contextualised identities of school-based teacher educators. At a time of systemic change in the education systems of many countries, teachers in schools are increasingly being asked to be responsible for the education and training of future teachers. Within the English backdrop of a rapidly changing landscape for teacher education, we present initial findings from a small-scale study exploring, through interview data, how the knowledge bases and identities of two groups of insiders, university and school-based teacher educators, were perceived by those hybrid teacher educators (Zeichner 2010) working in schools. Our findings reveal differences in school-based teacher educatorsâ views on their work and the work of university-based teacher educators, school-based teacher educatorsâ views on the role educational research has in the work they do and the ways in which different professional pathways (e.g. occupational/university; primary/secondary) influence views on what it means to be a teacher educator
Professional development for professional learners: teachersâ experiences in Norway, Germany and England
Proposals made by the European Commission in 2007 led to the Education Council adopting, for the first time, a European agenda for improving the quality of teaching and teacher education. This article reports on a small-scale longitudinal interview-based study with teachers in England, Norway and Germany demonstrating that while opportunities for professional development are increasing in all three countries, dissatisfaction is expressed by most teachers in relation to its quality and outcomes
Appeals to evidence for the resolution of wicked problems: the origins and mechanisms of evidentiary bias
Wicked policy problems are often said to be characterized by their âintractabilityâ, whereby appeals to evidence are unable to provide policy resolution. Advocates for âEvidence Based Policyâ (EBP) often lament these situations as representing the misuse of evidence for strategic ends, while critical policy studies authors counter that policy decisions are fundamentally about competing values, with the (blind) embrace of technical evidence depoliticizing political decisions. This paper aims to help resolve these conflicts and, in doing so, consider how to address this particular feature of problem wickedness. Specifically the paper delineates two forms of evidentiary bias that drive intractability, each of which is reflected by contrasting positions in the EBP debates: âtechnical biasâ - referring to invalid uses of evidence; and âissue biasâ - referring to how pieces of evidence direct policy agendas to particular concerns. Drawing on the fields of policy studies and cognitive psychology, the paper explores the ways in which competing interests and values manifest in these forms of bias, and shape evidence utilization through different mechanisms. The paper presents a conceptual framework reflecting on how the nature of policy problems in terms of their complexity, contestation, and polarization can help identify the potential origins and mechanisms of evidentiary bias leading to intractability in some wicked policy debates. The discussion reflects on whether being better informed about such mechanisms permit future work that may lead to strategies to mitigate or overcome such intractability in the future
Object Registration in Semi-cluttered and Partial-occluded Scenes for Augmented Reality
This paper proposes a stable and accurate object registration pipeline for markerless augmented reality applications. We present two novel algorithms for object recognition and matching to improve the registration accuracy from model to scene transformation via point cloud fusion. Whilst the first algorithm effectively deals with simple scenes with few object occlusions, the second algorithm handles cluttered scenes with partial occlusions for robust real-time object recognition and matching. The computational framework includes a locally supported Gaussian weight function to enable repeatable detection of 3D descriptors. We apply a bilateral filtering and outlier removal to preserve edges of point cloud and remove some interference points in order to increase matching accuracy. Extensive experiments have been carried to compare the proposed algorithms with four most used methods. Results show improved performance of the algorithms in terms of computational speed, camera tracking and object matching errors in semi-cluttered and partial-occluded scenes
Unseen roots and unfolding flowers? Prison learning, equality and the education of socially excluded groups
The objective of this theoretical article is to critique the notion that adult education, in its current marketised formations, might serve the purpose of rehabilitating learners. To date there has been no detailed interrogation by educationalists of the desirability of rehabilitation as an overarching aim for prison education, or to consider the existing educational philosophies that notions of rehabilitation might cohere with. This article begins to address this gap by engaging with the idea of rehabilitation from a critical adult education perspective. The conceptual framework informing the analysis is critical adult education theory, drawing tangentially on the work of Raymond Williams. The overarching assumption is that education might be understood as the practice of equality, which I employ alongside conceptualisations of empowering adult literacies learning as drawn from writings in the field of New Literacies Studies (NLS). These approaches enable the critique of criminological theory associated with prison learning, alongside the critique of assumptions traceable to NLS. The analysis focuses more specifically on Scotlandâs prison system, where the criminological theory of âdesistanceâ currently holds some sway. I observe that whilst perspectives of criminologists and educationists draw upon similar sociological assumptions and underpinnings, different conclusions are inferred about the purpose and practice of adult learning. Here criminologists' conceptualisations tend to neglect power contexts, instead inferring educational practices associated typically with early years education. I also demonstrate the importance of equality in the context of adult education, if educators are to take responsibility for the judgements they make in relation to the education of socially excluded groups
