如何提高网络环境下形成性评价的反馈质量——北外网院的实践

形成性评价在远程教学中发挥了重要的作用。科学的形成性评价不仅可以帮助学生理清课程学习重点,还可有效地督促学生学习。反馈是形成性评价的重要环节,及时有效的反馈对于远程学习者尤为重要。本文介绍并评估在北京外国语大学网络教育学院(以下简称"北外网院")开展的一项旨在提高形成性评价反馈质量的教学实验。结果表明,实验教师认识到反馈的重要性并能够提供有效反馈。研究提出的基于网络的教师反馈监控机制对于保证和提高远程教学质量的探索将有重要的启示作用。     

Maintaining Research Documents with Database Management Software

Summary

This article reviews the development and delivery of a Higher Education course module as part of a large European University's Integrated Masters Program operating through a regional network of Rural Area Training and Information Opportunities (RATIO) telematic centres. The aim of the project was to provide remote learners living in the southwest of England with computer-supported solutions to access higher education as part of a technology-assisted distance education program. The module represented a shift from traditional educational delivery systems by using instructional courseware via an Internet Web site. Personal communications with module participants were conducted with the use of e-mail and videoconferencing information technology (IT) resources. Out of the original sixteen participants who enrolled in this Masters course module, four actually completed the learning sessions and two submitted final assignments. This article considers the key lessons learned from this attrition rate and shares the mainly positive experiences of the remote tutor and the students engaged in this initiative. The implications regarding the use of the Internet for delivering higher education course modules through online distance learning are discussed in the light of cautions learned from this research project and important practical recommendations for future practice are made.

The Use of Smartphones in Primary Education： Improving Arithmetic Calculations in Pre-service Primary Teacher Training

It is difficult for teachers to track student learning on a daily basis. However, the Intemet and new technologies that students use every day can make this much easier and more accessible. This article intends to make evident that using student response systems, such as Socrative and a smartphone, teachers can get more control of their students＇ pace of learning and their progress. Socrative is a very useful tool that helps teachers track student learning in real time. Socrative software can be downloaded on students＇ smartphones, tablets, or laptops and can facilitate online testing with immediate feedback and access to test results. Students receive immediate feedback as soon as they finish answering test questions. It can also promote cooperative learning when students work in groups discussing coursework. Use of the software can increase motivation, self-esteem, and understanding of concepts discussed in class.

论学习的研究范式与视界

影响人的学习的最重要因素是什么?不同的教学理论对此给出了大相径庭的答案,这是因为它们各自对学习本身持有不同的视界,有的看重预期的学习结果,有的聚焦影响学习过程的各种方法,还有一些则抓住了学习发生的条件.有八种对教育传播与技术领域的理论发展一直产生影响,并且仍在产生强烈影响的最流行研究范式,它们分别是完形心理学、行为主义和新行为主义、发展心理学、文化—历史学派、信息加工理论、认知符号理论、认知资源理论和社会建构主义.一般来说,研究总是在某个特定的范式框架内进行的,但是研究者应该认识到,范式本身会对研究方法和结果产生很深的影响.更重要的是,研究者应该对各种不同的理论与范式持开放的心态,因为新的发现总是出现在不同范式之间的交叠磨合处.     

宽带综合业务数字网(B-ISDN)

宽带综合业务数字网 (B -ISDN)是窄带综合业务数字网 (N -ISDN)发展的高级阶段。它的基本组成部分是一个采用异步转移模式 (ATM)交换的能实现固定比特率 (CBR)和可变比特率 (VBR)的端至端连接的通讯网。B -ISDN的通信服务除了能提供N -ISDN所提供的各种通信服务外 ,还能提供交换型服务和分配型服务 ,并有自己的服务特点。B -ISDN的智能化为它的应用与发展提供了广阔的前景。     

Text Mining 101: What You Should Know

ABSTRACT

Scholars increasingly use text and data mining (TDM) methods to discover trends and relationships within complex digital data sets. In order to support this development in scholarly communication, librarians and publishers need to be knowledgeable about TDM methods, build partnerships with TDM researchers, and address challenges related to licensing and access to large document sets. The presenters of this NASIG session shared their experiences of supporting TDM as a library subject liaison, acquisitions librarian, and publisher representatives. Audience members discussed issues involving TDM of data from multiple publishers, local hosting of data sets and TDM activity by undergraduate students.
