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   

Objectivity as standardization in data-scientific education policy,technology and governance     

Ben Williamson  Nelli Piattoeva 《Learning, Media and Technology》2019,44(1):64-76

ABSTRACT

New data-driven technologies appear to promise a new era of accuracy and objectivity in scientifically-informed educational policy and governance. The data-scientific objectivity sought by education policy, however, is the result of practices of standardization and quantification deployed to settle controversies about the definition and measurement of human qualities by rendering them as categories and numbers. Focusing on the emerging policy agenda of ‘social and emotional learning and skills,’ this paper examines the practices of ‘objectivity-making’ underpinning this new field. Objectivity-making depends on three translations of (1) scientific expertise into standardized and enumerable definitions, (2) standardization into measurement technologies, and (3) the data produced through measurement technologies into objective policy-relevant knowledge, which consolidates a market in SEL technologies. The paper sheds light on knowledge-making practices in the era of big data and policy science, and their enduring reliance on the precarious construction of objectivity as a key legitimator of policy-relevant scientific knowledge and ‘evidence-based’ education governance.  相似文献   

马克思的社会有机体论与社会发展标准     

贺晴 《渭南师范学院学报》2011,26(3):20-22

马克思的社会有机体理论认为社会是由人的实践所引起的各种因素相互制约有机联系的整体。它揭示出人是社会的主体,社会发展的标准就是使社会有机体良性运行,马克思的社会有机体理论深化了唯物史观关于社会发展标准理论,并为落实科学发展观奠定了理论基础。  相似文献   

马克思的历史进步尺度思想对“和谐发展”的启示     

李春生 《襄樊学院学报》2011,32(9):32-35,40

科学发展与社会和谐的结合就是"和谐发展"。马克思的历史进步尺度思想对"和谐发展"有多方面的启示:生产力的发展归根到底会促进人的发展;生产力的发展程度是人的发展程度的标识;"共同富裕"是生产力与人"和谐发展"的归宿;主体创新能力是科学发展的可持续力。唯有实现"和谐发展",才能真正实现生产力发展与人的自由全面发展这两个社会进步尺度的有机的内在统一。  相似文献

Metaphors we’re colonised by? The case of data-driven educational technologies in Brazil     

Giselle Martins dos Santos Ferreira  Luiz Alexandre da Silva Rosado  Márcio Silveira Lemgruber  Jaciara de Sá Carvalho 《Learning, Media and Technology》2020,45(1):46-60

ABSTRACT

This article discusses issues concerning the spread of data-driven educational technologies in Brazil. Here, as elsewhere, educational technology continues to be promoted optimistically as the bearer of a panacea for historically-rooted social problems. Whilst some of these technologies have indeed contributed to important widening-participation programmes in the last two decades, widespread advocacy of technological ‘solutionism’, reflected in gradually stronger policy demands for efficiencies to be improved through ‘innovation’, has supported a relentless marketisation of the country’s educational systems. As transnational corporations position themselves to take control of key areas of these systems, threatening to restructure the whole sector, data-driven educational technologies provide the latest example in a series of ‘new’ ideas offered in an ever-expanding market. Based on the notion of ‘conceptual metaphors’, which encapsulate specific ways of perceiving, thinking and relating with the world, this article examines key metaphors underpinning discourses surrounding data-driven educational technologies in Brazil. In particular, the article analyses ways in which these specific metaphors may be promoting perspectives that ignore difference and obscure broader questions concerning education, thus contributing to the reproduction of previously existing problems and supporting new forms of colonisation.  相似文献
