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

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

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 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

在西方哲学中,逻辑和知识的关系是一个根本问题。理论理性的根本问题之一就是运用逻辑阐明人类知识的来源及其性质。逻辑是思想的语法形式。西方传统的形式逻辑是关于判断及其诸形式的学说,即命题逻辑或陈述逻辑,其核心是述谓判断。康德把经验直观的内容(质料)排除在逻辑之外,胡塞尔则认为逻辑的东西必须到直观内在体验中寻找其隐秘的起源,这就把逻辑的东西的范围延伸到了前述谓经验的领域,并试图通过澄清逻辑的起源方式以便对述谓判断的本质作出解释,找到真正通往真理本身之起源的道路。  相似文献

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
