对数字时代远程开放教育规划的再思考     

邓立真  王景政 《云南电大学报》2006,8(4):18-23

在过去30多年里发生的主要技术突破和社会发展是改变环境的主要驱动力,但其他的因素诸如日益增长的学习需求、教育服务的商业化、全球化和经济自由化等也是促成重新定义的原因。从某种程度而言,审视技术、技巧、效率、效果以及实用价值等多方面的问题,是远程教育院校在从事在线远程开放教育事业时所面临且必须应对挑战和抉择。  相似文献

Moving beyond the predictable failure of Ed-Tech initiatives

ABSTRACT

The development of Information and Communication Technology has created waves of excitement about its power to fix educational problems and improve learning results, prompting a succession of policy efforts to integrate digital technology into education. Educators, schools and corporations are increasingly driving these initiatives. This article makes the argument that a narrow vision of digital technology, which both ignores the complexity of education and wastes valuable public resources, is becoming an obstacle to significant improvement and transformation in education. Utilising our research and experience in the field of educational technology, this paper problematises the common elision of ‘technology’ and ‘digital technology’. From this basis, we then critically reflect on various common approaches to introducing digital technology in education under the guise of promoting equality and digital inclusion. These include national government-led programmes, more recent trends for local school-led initiatives, and the role of non-formal education initiatives led by corporations/foundations. Amidst the varying surface-level ‘failure’ and/or ‘success’ of these approaches, we point to limited underpinning ‘information and knowledge society’ logics in framing the application of digital technology to education. As such we conclude by considering the educational challenges for future Ed-Tech initiatives.  相似文献

Splicing the Divide: A Review of Research on the Evolving Digital Divide Among K–12 Students     

Jennifer E. Dolan 《Journal of Research on Technology in Education》2016,48(1):16-37

The digital divide has narrowed with regard to one definition of access to technology—the binary view of the “haves” and “have-nots.” However, use of technology at home and in school is not equitable for all students. According to recent literature, a broader and more nuanced definition of the technological divide is necessary in order to express the ways technology is used or not used. The purpose of this research review is to examine the defining characteristics of technology use by K–12 students, highlighting the complexities of the evolving digital divide. This review integrates findings from empirical studies, theoretical articles, research reviews, and government surveys in the United States in order to present a renewed look at an evolving digital divide, explore the underlying causes of the unequal student use of technology, suggest directions for future research, and provide current implications for practice.  相似文献   

Digital downsides: exploring university students’ negative engagements with digital technology     

Neil Selwyn 《Teaching in Higher Education》2016,21(8):1006-1021

Digital technologies are now an integral feature of university study. As such, academic research has tended to concentrate on the potential of digital technologies to support, extend and even ‘enhance’ student learning. This paper, in contrast, explores the rather more messy realities of students’ engagements with digital technology. In particular, it focuses on the aspects of digital technology use that students see as notably unhelpful. Drawing on a survey of 1658 undergraduate students from two Australian universities, the paper highlights four distinct types of digital ‘downside’. These range from low-level annoyances and interruptions, to ways in which digital technologies are seen to diminish students’ scholarship and study. Against this background, the paper considers how discussions of digital technology might better balance enthusiasms for what we know might be achieved through technology-enabled learning, with the often unsatisfactory realities of students’ encounters with digital technology.  相似文献

电机控制数字信号处理器最小测试指令集的分析和寻找     

严伟  曹家麟  龚幼民 《上海大学学报(英文版)》2005,9(2):147-152

The relativity of instructions of motor control digital signal processor (MCDSP) in the design is analyzed. A method for obtaining a minimum instruction set in place of the complete instruction set during generation of testing procedures is given in terms of the processor presentation matrix between micro-operators and instructions of MCDSP.  相似文献
