Making sense of learner and learning Big Data: reviewing five years of Data Wrangling at the Open University UK     

Bart Rienties  Simon Cross  Vicky Marsh  Thomas Ullmann 《Open Learning》2017,32(3):279-293

Most distance learning institutions collect vast amounts of learning data. Making sense of this ‘Big Data’ can be a challenge, in particular when data are stored at different data warehouses and require advanced statistical skills to interpret complex patterns of data. As a leading institute on learning analytics, the Open University UK instigated in 2012 a Data Wrangling initiative. This provided every Faculty with a dedicated academic with expertise data analysis and whose task is to provide strategic, pedagogical and sense-making advice to staff and senior management. Given substantial changes within the OU (e.g. new Faculty structure, real-time dashboards, two large-scale adoptions of predictive analytics approaches, increased reliance on analytics), this embedded case study provides an in-depth review of lessons learned of five years of data wrangling. We will elaborate on the design of the new structure, its strengths and potential weaknesses, and affordances to be adopted by other institutions.  相似文献   

Transformative and emancipatory literacy to empower     

Vicky Duckworth  Lyn Tett 《International Journal of Lifelong Education》2019,38(4):366-378

ABSTRACT

This paper draws on sociological and critical educational frames, particularly Bourdieu’s concept of symbolic violence, in order to contest the dominant model of literacy education that is driven by the premise of a ‘knowledge economy’. Instead it foregrounds the political, social, and economic factors that marginalise learners. Data from two projects: an ethnographic study in a Further Education (FE) College in England and a study of community-based literacy programmes in Scotland, are probed to show how literacy classes can offer spaces to challenge symbolic violence and facilitate learners to reclaim identities of success. These changes are illustrated from the learners’ views of the contrasts between their experiences of school education and literacy programmes that use transformative and emancipatory approaches. Our research demonstrates how critical education can open up spaces for a more equitable approach based on the co-production of knowledge. It is argued that making changes to policy and practice could inform and shape the literacy curriculum and its pedagogy if adult literacy can disentangle itself from instrumental approaches driven by neoliberal fusion and instead create critical space for contextualised and emancipatory learning.  相似文献   

Primary physical education subject leadership: along the road from in-house solutions to outsourcing     

Gerald Griggs  Vicky Randall 《Education 3-13》2019,47(6):664-677

The modern primary school is a complex institution containing a growing community of individuals and organisations with potentially competing agendas. Within this environment, subject leaders are typically looked upon for advice and guidance within a given subject area such as Physical Education. Yet for those endeavouring to provide Physical Education subject leadership within primary schools, the challenge has grown significantly over the last two decades amidst an ever-changing policy landscape. This paper is for and about primary Physical Education subject leadership; the purpose of which, to plot primary Physical Education's policy journey and explore the implications of reform in shaping the subject leader's role. The paper addresses the current lack of guidance for the subject leader and examines the professional knowledge, skills and experience required to do the role effectively.  相似文献   

Chronic flexibility gains: effect of isometric contraction duration during proprioceptive neuromuscular facilitation stretching techniques     

Rowlands AV  Marginson VF  Lee J 《Research quarterly for exercise and sport》2003,74(1):47-51

The aim of this study was to assess the effect of to isometic contraction durations during propiceptive neuromuscular facilitation stretching on gains inflexion at the hip. Forty-three women (M age = 20.0 years, SD = 1.3) were assigned to one of three groups: 5-s isometric contraction (5-IC), 10-IC, and control. Flexibility was assessed at baseline and Weeks 3 and 6. Analysis of covariance, controlling for pretest differences, showed a significant interaction, F(2, 33) = 44.1, p < .001. Flexibility was significant lower in the control group relative to the 5-IC and 10-IC groups and in the 5-IC group relative to the 10-IC group at 3 and 6 weeks (3 weeks = 101.2 +/- 1.4 degrees, 114.3 +/- 1.5 degrees, 120.5 +/- 1.3 degrees; 6 weeks = 103.0 +/- 1.4 degrees, 126.1 +/- 1.6 degrees, 133.3 +/- 1.4 degrees for control, 5-IC and 10-IC groups, respectively). A longer contraction time led to greater increases in flexibility.  相似文献   

Indigenous students' persistence in higher education in Australia: contextualising models of change from psychology to understand and aid students' practices at a cultural interface     

Andrew Day  Vicky Nakata  Martin Nakata  Gregory Martin 《高等教育研究与发展》2015,34(3):501-512

The need to address the substantial inequities that exist between Indigenous and non-Indigenous Australians in higher education is widely recognised. Those factors that affect the performance of Indigenous students in tertiary education have been reasonably well documented across different institutions, disciplines, and programme levels but there has, to date, been less consideration of the processes by which Indigenous students either persist or desist in higher education. This paper aims to present a conceptual understanding of academic persistence that can inform the delivery of tailored academic support interventions to Indigenous students who are at high risk of leaving higher education.  相似文献   

Digital body preservation: Technique and applications     

Vicky Vandenbossche  Joris Van de Velde  Stind Avet  Wouter Willaert  Stian Soltvedt  Noeska Smit  Emmanuel Audenaert 《Anatomical sciences education》2022,15(4):731-744

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.  相似文献   

Reading nonfiction text on an iPad in a secondary classroom          下载免费PDF全文

Victoria Cardullo  Vassiliki “Vicky” I. Zygouris‐Coe  Nance S. Wilson 《Journal of Research in Reading》2017,40(Z1):S190-S208

The intent of this research was to investigate the experiences of eighth grade readers as they read nonfiction text on an iPad for academic purposes. We investigated reading strategies that students use to support their reading as well as what role iPad features played in the reading process. New literacies, metacognition and transactional theories informed the framework. Multiple data sources were used to triangulate findings and included (a) retrospective think alouds, (b) student iPad survey, (c) pre and post study student interviews, (d) Metacognitive Awareness of Reading Strategies Inventory and (e) student observations. Data for the collective case study participants focused on the identification of proficient readers who displayed confidence, competency, and control over text. Themes identified in the collective case studies included (a) reading comprehension strategies, (b) nonfiction features and (c) iPad features to support their reading of nonfiction on the iPad.  相似文献   

Internal and external focus of attention in a novice form sport     

Lawrence GR  Gottwald VM  Hardy J  Khan MA 《Research quarterly for exercise and sport》2011,82(3):431-441

In the current experiment, we examined optimal focus for novices during a movement sequence in which performance was measured on accurate movement form/technique. A novel gymnastics routine was practiced under either an internal skill-relevant, internal skill-irrelevant, external, or no attention focus. Retention and transfer tests were then completed. During acquisition, adopting an internal irrelevant focus significantly improved performance, whereas an external focus degraded performance. There were no significant group differences in the retention and transfer tests. This suggests that learning of movement form/technique did not benefit from a specific focus of attention. The results are interpreted via an attentional capacity viewpoint and the notion that form tasks do not always contain obvious movement effects central to common coding and the constrained action hypothesis.  相似文献

Addressing 21st-century crises through children’s literature: picturebooks as partners for teacher educators     

Patricia A. Crawford  Sherron Killingsworth Roberts  Vicky Zygouris-Coe 《Journal of Early Childhood Teacher Education》2019,40(1):44-56

ABSTRACT

Teacher educators might consider using high-quality picturebooks as partners to help teacher candidates understand and navigate today’s painful world realities. From a critical perspective, these books also have the potential to reflect and shape empathy and action in regard to these difficult situations. This piece includes a rationale for using picturebooks to address human crises, findings related to a study of 21st-century representations of crises in picturebooks, and implications for sharing these books as pedagogical partners to engage with teacher candidates. To this end, we conducted a content analysis of recent 21st-century fictional picturebooks depicting human crises. Topics related to refugee status, poverty, homelessness, and hunger were analyzed to reveal common themes across these books related to persistence, courage, caring, and hope. Teacher educators who are eager to address 21st-century disasters, many of which are presented in sensitive and accessible ways in recent touchstone picturebooks, can find a ready and capable partner in these powerful picturebooks to help readers understand and navigate these human crises.  相似文献
