随着网络技术的日臻成熟、Internet的迅速延伸及校园网络的普遍建立,网络教育得到了越来越广泛的应用。但目前的网络教学系统普遍存在智能性差、交互手段匮乏、知识结构松散、资源共享度不高等一系列弊端。本文以多Agent技术为基础,提出了一个新的基于多Agent的智能网络教学系统模型,并讨论了系统中各部分的主要功能及实现本系统的部分关键技术。  相似文献   

Teaching and learning in microsystems engineering     

Resham S. Dhariwal  Marc P.Y. Desmulliez 《European Journal of Engineering Education》2005,30(3):341-352

Whereas research in MicroSystems Technology (MST) has grown rapidly over the last twenty years, the education of engineers at postgraduate level is still in its infancy. The number of dedicated MST research institutions, companies and university laboratories worldwide has grown at a dramatic rate and all require trained individuals who can be immediately operational in the workplace. With the possible exceptions of Germany and Switzerland, the authors of this article believe that the training requirements for such scientists, engineers and technicians have not been satisfactorily addressed as yet. Realising the need for adequate training in MST, the British funding agency for research in science and engineering, the EPSRC (Engineering and Physical Sciences Research Council) awarded a substantial grant to Heriot-Watt University in order to set up a Masters Training Package (MTP). The context of this grant, the syllabus developed for this Master of Science as well as its implementation are presented in this article. Advantages and drawbacks of block-based delivery of the course are presented from a pedagogical point of view for the different categories of students (full-time students, part-time students and company delegates).  相似文献

用教育技术引领教育改革——论我国教育技术的定位(二)     

张祖忻 《现代教育技术》2007,17(7):5-10,18

教育技术是一项解决教育问题的系统技术,可用于推动教育、教学的各个层面上的改革。但二十多年来,由于认识受限,定位不当,我国这一领域的工作偏重于硬件设施建设与服务、教育媒体制作、教学方法改革等方面,且这些活动大部分在战术层面上开展,教育技术没有发挥更大的作用。当前,我们应关注在战略层面上实施教育技术,追求“效果、效率和效益”,即教育绩效,这是我国穷国办大教育的国情所要求的。战略优先,战术配合,战略战术互动,促进教育整体改革,落实科学发展观,这应成为信息化进程中我国教育技术高起点新发展的指导思想,成为我国教育技术学科知识体系构建研究的基本思路。用教育技术引领教育改革,在宏观层面上应重视需要的评估和系统规划,确保“做对的事情”;在中观层面上要推广教学系统设计,在微观层面上要加强对研究成果的运用,确保“把事情做对”。目前我国教育技术界电教人员或计算机科学人员的工作仅是教育技术的一个组成部分,教育技术也是各级教育管理者和广大教师的共同事业。  相似文献   

Relational Maintenance in the Digital Age: Implicit Rules and Multiple Modalities     

Jen Eden  Alice E. Veksler 《Communication quarterly》2016,64(2):119-144

The present project utilized a mixed methods approach to examine how individuals use CMC to maintain proximal relationships. Nine different communication channels were examined concurrently to elucidate how frequently mediated relational maintenance is used and to examine what participants reported in terms of motives for use and avoidance of particular channels. Findings indicate that participants in proximal relationships are hyper-aware of the amount of intimacy implied by a particular communication channel and strategically engage channels to suit their needs. We propose that relationships will be difficult to maintain if people violate the implicit rules that appear to govern channel selection.  相似文献   

信息技术与课程整合的教学模式研究之二——“传递—接受”教学模式   总被引：2，自引：0，他引：2  

何克抗  吴娟 《现代教育技术》2008,18(8):8-13

该文是系统研究"信息技术与课程整合教学模式"系列研究论文的第二篇。这组系列研究论文对信息技术与课程整合实施过程中广大教师必须面对的重要问题——"对信息技术环境下教学模式的内涵与特征应如何正确认识、以及对这类教学模式应如何有效实施"作了较深入的探讨;该文则着重对课内整合模式中的主要代表之一"传递—接受教学模式"进行研究,并从该模式的产生背景、内涵与特征、实施步骤及实施案例等几个方面做出比较深入的阐述。  相似文献   

Educational Research for Policy and Practice in Japan – With Particular Reference to Youth Education     

Taro Numano  Yoshiyuki Nagata  Mariko Ichimi Abumiya 《Educational Research for Policy and Practice》2002,1(1-2):35-50

Based upon the Fundamental Law of Education, Japanese school education system has long been a source of pride for the country as a result of the high school participation rate, the homogeneity of compulsory education throughout the country. However, the confidence of the people in its schools is now showing severe signs of strain and fatigue. In recent years, there have been many reports about the growing seriousness of a number of educational problems having to do with young people in their childhood and adolescence. Since the mid-1970s, a number of problems have been highlighted. They include violent behavior, juvenile crimes, bullying, refusal to attend school, dropping out at secondary level of education, and corporal punishment. Against the above background, based on recommendations from such advisory bodies as the Central Council for Education and the National Commission on Education Reform, the Ministry of Education, Culture, Sports, Science, and Technology (MEXT) has adopted a range of policies and launched a series of educational reform programmes. For instance, what is called “Rainbow Plan”, based on the final report submitted by the National Commission on Education Reform, provides the country with basic guidelines for the educational reform in the near future. Roles of educational research for making policies have been of significance. Research initiated by the National Institute for Educational Policy Research (NIER) and the National Federation of Educational Policy Research Institutes (NFERI) is an example of contributions to the development of educational qualities in the country. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

对李约瑟<中国科学技术史》若干问题的消解     

王汝发 《广西师范大学学报(哲学社会科学版)》2003,39(2):139-142

已故英国名科学史家李约瑟博士对中国科学技术史进行了深入探讨，其所的《中国科学技术史》对中国古代科学技术作出了实事求是的总结与概括，并提出了一些极有启发性的独创见解，对世界了解中国，消除误解与偏见作了极好的宣传。他对中国科学技术史的研究不存在“拔高”或“说好话”的倾向。他的《中国科学与明》被译成《中国科学技术史》并无不妥。否定“李约瑟难题”缺乏理论根据。  相似文献   

现代远程教育技术在北京农村科技推广与信息服务中的实践研究   总被引：1，自引：0，他引：1  

郭建鑫  孙素芬 《现代教育技术》2003,13(3):22-26

农民作为现代农业的主体,提高其文化素质的、现代农业科技知识和技能水平以及市场经营能力,将直接影响到农村经济发展进程和效果。传统的农业科技推广模式与传播途径已经无法满足农村经济发展对科技和劳动力素质的要求。北京农村远程信息服务工程中心在研究分析北京农村居民采用农业科技的行为特征和学习障碍的基础上,率先在全国将现代远程教育技术引入农业科技推广与信息服务工作,建立起以覆盖北京地区为主的农村远程信息服务系统。该文对系统研究应用过程中涉及问题进行分析介绍,以供参考。  相似文献   

论邓小平发展观中的"科技"思想     

牛佳 《内蒙古师范大学学报(哲学社会科学版)》2007,36(6):110-113

邓小平的发展观是邓小平理论的重要组成部分，是涵盖了建设有中国特色社会主义的发展道路、发展动力、发展关键、发展模式、发展目标、发展战略、发展的依靠力量等各个方面比较完备的理论体系。邓小平的科技思想在这个理论体系中得到了充分的体现。笔者就发展的关键——科学技术是第一生产力，发展的目标和战略——科学技术的现代化，发展的模式——科学技术的自主创新，发展的依靠力量——科技人才等四个方面进行了粗浅的论述。邓小平发展观中的科技思想，对于当前和今后的社会主义现代化建设，具有十分重要的指导意义。  相似文献
